You forgot to mention that the BMW boxer engines has a gyroscopic effect that actually provides more stability to your lean angles, ride one and you'll know.
I love the BMW Boxer engines, you are just reading specs. The feel; of a boxer is unique and worthy of much more praise than you offered. Try taking a 1200 gs across the USA, without using the Interstate.
It's extremely wide, making very clunky design, getting in the way, much more likely to be damaged, and limited lean angle. Makes more sense in a car, except it makes changing spark plugs excessively difficult. Can also have issue with excessive oil leaking into cylinder when sitting a while since pistons are sideways.
@@xeridea Would be better if you actually knew anything about them. My R1100S has a lean angle of 49 degrees. With the optional longer shock, it is 52 degrees
When riding a BMW with the boxer engine, you'll touch your pegs or drag your knee long before the cylinders contact. BMW has made rr bikes that use the boxer configuration.
My R80 leaned further than any Triumph I ever rode, and had about the same clearance as my Commando. I don't think the guy who made this video has ever ridden a Boxer.
I disagree with YammieNoob's statement that Boxer engines are hard to repair and maintain. Having previously owned an oil head boxer engine I can tell you they are WONDERFUL maintenance-wise. Valve adjustments are a snap. Easily done from a footstool in your driveway with no special tools. And any number of Airhead boxer owners can tell you stories of doing more major repairs at rally campsites. Then there is the longevity....it is NOT uncommon to hear of boxers going well over the 200,000 mile mark with only routine maintenance.
Yes boxer engine is easily accessible to work on. Had a 90 degree V twin, not easy to get to rear cylinder. Would never buy a V twin again unless it was a transverse mounted engine like on a Moto Guzzi. V4 must be hassle to work on but then again most V4 owners will never work on that engine themselves.
Boxers are very easy to maintain. The spark plugs or valves are easier to get to than with any other engine. They are super reliable, great sounding and the feeling while riding is unique. And NO! The lean angle is NOT limited by the cylinders. Its limited by the foot pegs. And I can say that by experience, because I drive a air cooled R 1200 R.
There have been two and they no longer exist for the good reason that they were complicated unreliable fuel-sucking pieces of junk. They really were a Wankel of an idea..
Love inline twins, my F800 has the flatest torque curve in the world. Yeah a triple or a V Twin would be a bit more exciting but my daily commute is nearly 80 miles each way and it's perfect for this job. That said I'd swap it for a Superduke R if I had the money.
V-twin con: 1. rear cycl cooling. 2. Added cost of maint for valve adjustments. Neither applies to east-west V-twins like Moto-Guzzo. Boxer pro: valve adjustment and main. Heads and valve covers exposure is a huge pro.
Rear cylinder cooling isn’t as big a deal as it’s made out to be. The cylinders are offset and the rear gets plenty of airflow. Valve adjustment point is totally valid though lol.
Yam,Yammy, yam,yam… Even though a boxer engine has some incredible limitations, it can be one of the smoothest best sounding engines you Ken put on a bike! Even though at about 50° you may not really need a kickstand, you can ride that bike hard down any twisty road if you truly know how to corner. Dynamic turns my bro!

blyat, western spy, no one have truly lived, until the have fallen asleep in a ural or Dnepr sidecar, after drinking a whole bottle of babushka´s kvass XD
I just purchased a Dnepr that's the military R-72 version of the Ural. The Ural was made for the Civilian market, and still is. My Dnepr had just 164 Km when I got it. Whoever built the top end at the factory was Vodka drunk! The right cylinder had zero compression and was not firing at all. It took a month to get parts from Russia but parts are dirt cheap. After fixing both cylinders I have it running perfectly. Being the military version it's slower than the Ural bike's by about 15 mph but who wants to go fast with a sidecar attached anyway? I love it because I've always been an attention whore and my Dnepr meets all expectations!
@@Rune2650 Back in 1939 BMW built R71's for their commercial and civilian customers. The military required different specifications than the R71 bikes. BMW didn't want to use the same model for both, which would cause confusion. They designated the military version of the R71 an R72. The Russians did the same giving their military spec bikes M72. The R72's had frames made of tubbing twice as thick as the R71 making them heavier and a spinning type oil filter fitted on the end of the crankshaft that was cleaned and reused instead of using disposable filter's in the R72 and M72 engine's. The R72 also had lower gearing and heavier load capacity as well. The R72 and M72 military grade motorcycles were truly different machines than the R71 bikes. You don't see any R72's today because the few that survived the war were destroyed at the end of the war.
I haven't owned a non-boxer car or motorcycle since I traded the K100RT for an R1100RT in 1995. No engine type is perfect, but boxers are perfect for me.
I thought of the K100/K1100 and laughed, when he said that inline-4s sacrifice lower center of gravity. What do you call that hunk of iron hanging below the frame? No hate though. The K bikes of yore are all but forgotten to many.
@@KalebWR I loved my K100RT but it was just so fuel hungry, somewhere around 45 mpgUK. The R1100RT is better in every way: same power, lighter, 60 mpgUK, better weather protection, more nimble, much better acceleration in lower gears (lower rotating mass). It's just missing a little top speed past 200 km/h that you never use.
@@timjohnson1199 Strange, the K75 are usually thought of as a lighter, more nimble model than the K100/1100. Smoother on the hands as well (bar vibration). You must be used to a very nimble bike, indeed.
Have a 1170cc R9T oilhead. The torque (~90 ft lbs) is only 4 away from Yammie's vaunted Hayabusa. He missed talking about the other benefits of the boxer- at 180 degrees the piston vibration is nil. Because of the low center of gravity it corners wonderfully.
Some of us still ride 2 stroke road bikes. I ride a 1977 CZ 350-472.1 twin nearly everyday as a commuter / run around. Weight = 291 Pounds. 343cc churning out 28 HP @ 5,250 RPM with 38 Pounds / Foot torque @ 3,800 RPM. (Makes the KTM 690's 43 Pounds / Foot not look so impressive now huh??!!). 2 strokes have a far longer service life (if not made in Japan) than 4 strokes and so will continue to exist so long as owners can find something to fuel them with.
@@CZ350tuner It uses twice as much fuel as he KTM to get anywhere and has half the low end torque. The fact that you quoted a 1977 bike as an example really says it all, two strokes are done.
V Twins can be pretty smooth and very powerful if they're 90 degree V twins. Smooth because a 90 degree V or L twin achieves perfect primary balance and powerful because the stroke is less than the bore diameter (over square). These V or L twins are commonly referred to as Crotch Rockets. Harley Davidson uses one of the worst and most inefficient designs, that being a push rod, 45 degree V with a stroke longer than the bore diameter (under square), take that along with large displacement and you have an engine design that will self destruct at anything over 6000 rpm. Those V Twins are commonly referred to as Crotch Tractors. ;)
In addition to the wankel rotary engine many have mentioned, there is also the rotary piston engine. Think of a boxer engine, but with 3 to 6 cylinders spaced evenly around the crankshaft, which has only one crank throw with an unusual connecting rod setup. They are popular in airplanes due to efficient air cooling, but there have been a few bikes with them. Then you have the Honda V3 and V5 race bikes. Having an odd number of cylinders allowed the engine to be narrower between the rider's knees while cramming in as many cylinders as they could. There is also the Horex VR6 engine which has such a narrow vee angle that it only uses one head. This configuration yields an engine that isn't as long as an inline six or as wide as a V6. Basically it allows you to put a 6 cylinder in the same space as a typical 4 cylinder. They also sound amazing! The only real downside is that the cylinder head is very complicated and can sometimes have sealing issues.
So many misconceptions in one video. A few: 1. Max torque depends on one thing really: displacement. Harley Davidson V2s are among the worst engines when it comes to torque/displacement ratio. Sportbikes are the best (just do the calculations). With lower torque it may be easier to get better torque (and power) at lower rpms, and that may be what confuses people about torque. 2. The lean angle on BMW boxers are never (well, I don't know about the 1200C models) limited by the cylinder heads. It might appear so but is is the footpins, central stand or. sometimes, the exhaust system that limit lean angle. For the R1X00GS models it's the footpegs. I think this is true even for the GSA models with the construction scaffolding added around the cylinders. 3. When you compare six cylinder inline engines, do not mention the Honda CBX in the same sentence as BMW K1600 other than for educating purposes. The Honda CBX is almost wider than it's long due to the engine. The CBX engine is ridiculously wide and on top of it they added some generator or something at the ends. The BMW K1600 is narrower than the four cylinder K1200 engine that preceded it and could probably power a sportsbike without appearing ridiculously wide. Almost.
"The CBX engine is ridiculously wide and on top of it they added some generator or something at the ends". INCORRECT only Honda's 4 cylinder engines of that time had an AC generator and a "something" on the end of their cranks. I do agree that the two bikes are very different what with the BMW having a 31 year tech. advantage. It seems to me that some people look back a little too favorably on those old CBX as the bikes did have their problems. Among those being that little issue of the con rods exiting the engine.
BMW makes the absolute best motorcycle imo. I have 1 and it's far superior to anything else I have ever owned. Their reliability is legendary. How many other bikes regularly get hundreds of thousands of miles? Very very few
7:00 I have to agree about the Triple being the best of all worlds. I moved up to a Tracer 9 GT & the triple engine is smooth, powerful, torquey & has great gas mileage. I'm hooked.
One MAJOR point was missed with the boxer engines (since I ride a boxer BMW): torque output is nearly maxed almost ALL rpm range! Also their very low center of gravity makes them very easy to handle. Makes it a great touring bike where you can pack half your house on it .. oh and don't forget your wife! Honda Goldwings also use these engines because of the same reason and just remember what Jay Leno said: "Horsepower sells a vehicle, but torque always wins a race".
Ducati and Suzuki use a 90 degree v twin design , Harley doesn't, big difference. Very smooth design with no counterbalances needed. The Suzuki SV 650 v twin is a great bike at a great price. Yes , I own one!
@@kirarittberg5088 The differences between a Ducati V-twin and a HD V-twin go much deeper than cylinder angle. It's basically like comparing a Ferrari V8 to a Ford Crown Victoria V8.
Awesome video ........how about Guzzi's V Twin mounted sideways ,rotary engines and factory turbo's from the late 80's (engines that failed in bikes segment?). Also how about a similar segment on primary drive methods e.g. belt versus chain versus shaft and the pro n cons of each.
7:24 The best way to balance out a 900cc inline triple is add an opposing 900cc triple set of cylinders. With a power stroke every 120...... WAIT, OH YEAH! That would be a Valkyrie engine.
@@theoldman8877 Indeed! That Honda model (IIRC it was something like CR-X ?) is the only other transverse-v I've ever seen - not nearly as pretty as the Guzzi tho...
Wow... there are a suprising number of vocal Guzzisti in here. Although... Notably an Italian inspiration. I love my Nevada. I also love my R75, which made me frown when I saw the clickbait.
BMW has been putting opposed engines in their motorcycles since 1923. What could they possibly know ? This guy gets off on listening to himself rattle off a bunch of specs like he's some kind of m/c guru..............
I love in-line 3-cylinders, but is it true that they get better gas mileage? By the specs, a lot of 2020 in-line 4's claim higher gas mileage. Are they fudging the numbers?
Worth noting that some of the modern parallel twins have a "dead" 3rd cylinder that is just a counter weight. A good example is the 800cc BMW twin. They wanted to retain the firing order and smoothness of their opposed twin. Solution, make both pistons go up and down together and have a counter weight that run opposite between them. Since both pistons hit TDC together, the smooth 360 degree firing is retained, and there is virtually no vibration. I recently moved from the DFW TX area to northern NJ. Most of the roads around here are 45 mph and lined with trees. I would have never thought I'd own less than a 1000 CCs again, but up here, a smaller bike makes a ton of sense. A great deal came up on an F800GT, it was great fun on the roads around here, so I bought it. I was pretty amazed how much this motor did feel like the older opposed twins.
Same story for the V8. And I think the V12. That is why those are so popular: they are faster because they have no extra weight rotating to correct unbalance. Opening the throttle, you do not want extra rotating weight. Simple. First I thougt the 90° V4 and V6 are balanced too, but that is wrong. Perhaps a 2 stroke V6 would... Check it yourself! Just like those crossplane crankcases, it is all about torque and power delivery, all engines are different. Just ride the Kawasaki ER or Versys 180° twin. And compare it to the Yamaha MT-07 270° twin. Both very good, and so different. Before you buy a parallel twin, you'd better know how many degrees are involved. Or simply ride it and feel if you like it. I was kind of addicted to the TDM 900, a tourer 270° twin. Now it's a single piston for me.
@@voornaam3191 Keller is working on an 90° V3, which uses one 320 cc piston opposite two 165 cc slugs, using a "big bang" firing order. His goal is a balanced, smaller package that has the positive attributes of the inline 3,4 and the V twin. Anyone interested in 14,000 rpm and low end torque?
@@johntempest267 Great idea. That big bang firing order really works. I've been thinking about modifying a V engine, usually it is a 270° firing order, but you could turn the camshafts, adjust the ignition and make it a 90° firing order. Like the big bang. You might need a stronger clutch and all. Or limit the revs, to keep everything standard and still get that big bang feeling. But actually doing, well, not enough guts for it. It might cost me a bike. And I have no spare money available. But it might be a funny project... Just think about it, for a parallel twin you'd need new modified camshafts. You need tools for that, suppose you could get camshafts for machining your own design of cams. But for a V twin, you have two sets of camshafts and a chain. That way adjusting the valves for ignition 90° after the other cilinder is easy. But if there are balance shafts, things get complicated. So you absolutely need a proper 90° twin, a 70° twin (like in Honda Transalp) is more complicated, I'd ruin its balance.
@@voornaam3191 Having access to state of the art 3d printers and Clemson University's super computer is helpful. This motor exists as a mock up and digital virtual at present. Casts for the cases is complete. Last I heard, they're tweaking the crankshaft to try various stroke length combinations to get harmonic characteristics ironed out. It's amazing this can be done virtually. This obviously will affect displacement, so he says it's a 600 to 650 cc design. All of this is way above my pay grade, but (as a SV 650 pilot) it fascinates me.
For me I want to know about bearings. When you have a twin like a Yamaha xs 650 you can ride the cam on six ball bearings . When you have a inline four the cam runs on the head without even babitt bearings. I like the center of gravity low so give me a pushrod engine.
On my NC700X the twin cylinders are tilted forward and there's only a single cam for the 8 valves. With the gas tank under the seat it makes for a nice, low CG.
another huge advantage of boxers is they are way more serviceable, valve clearance adjustment or plug replacement, i.e. are way easier to do. In my current 4l engine bike, replacing the spark plugs is a pain in the arse, it takes me over an hour, in a boxer engine that would take 10 minutes tops.
Yo, Yammie.... you missed a couple of points about the inline 6 configuration, ie that 1, the engine is perfectly balanced therefore will not find a better type for smoothness, but more importantly 2, the SOUND of an inline 6.... which is a truly sensual sound to any sort of petrolhead.
Yeach... funny that apparently hardly anyone in the comment section seems to note that. I came up on this guy's videos today and fter watching 3 I think it's a crap. Click bite title and a lot of biased claims delivered as if it was the ultimate truth. Not subscribing, not checking other.
The BMW F650 has a single cylinder engine, produces 52 ft pound of torque at low revs and is amazingly balanced and doesnt vibrate like crazy through the bars :)
You missed out the Guzzi transverse V-twin, and, the less well known experimental 3-cylinder W engine, a V with an extra cylinder in the middle. I won't mention radials.
I would like to point out that the Harley Davidson low redline is not driven by the fact that they are V-twins, but by their absolutely ridiculous piston and conrod sizes. the CX500 and CX650 engines from Honda have redlines at 10,000 RPM, and will quite happily pass 11,000 before valve float sets in.
Yammie REAL Question: Can you do a video based on motorcycle jackets VS Style jackets when riding a motorcycle? Last few weeks I used a fashion leather jacket to ride with. I noticed that for some weird reason the Right arm shoulder of the jacket started to wear out. I looked at an old fashion jacket I used to wear when riding and the Right should on that one was also becoming distressed. On both jackets the left arm side is completely fine. I couldnt find an answer online. My tradition biker jackets are fine however. Could you help me solve this mystery please? Thanks a lot. Your Fan!
Side note: Twisted road gets **30% for the cost of the rental**, so if you're thinking about listing the bike for rent it might not be worth the risk giving something unique to a squid with a death-wish.
In the Barber MC Museum they have a V12 Kawasaki made from the mating of 2 Kawasaki inline 6cyl engines. It's estimated to have between 200-300HP! When I saw it, all I could think was: "someone had way too much time on their hands..." VERY interesting, though. And the Museum is a "must-see" for all motorcycle folks.

Some of us still ride 2 stroke road bikes. I ride a 1977 CZ 350-472.1 twin nearly everyday as a commuter / run around. Weight = 291 Pounds. 343cc churning out 28 HP @ 5,250 RPM with 38 Pounds / Foot torque @ 3,800 RPM. (Makes the KTM 690's 43 Pounds / Foot not look so impressive now huh??!!).
2 strokes have a far longer service life (if not made in Japan) than 4 strokes and so will continue to exist so long as owners can find something to fuel them with.
@@CZ350tuner It uses twice as much fuel as he KTM to get anywhere and has half the low end torque.
The fact that you quoted a 1977 bike as an example really says it all, two strokes are done.
With new technology they might be back.
Fake news: maintenance on a BMW boxer is a breeze, except what is not mentioned here: changing the clutch disk.
Well.....After seeing what it takes to get to the alternator on a 1250GS.....BMW really made a mess of a maintenance friendly engine if you ask me.
V Twins can be pretty smooth and very powerful if they're 90 degree V twins. Smooth because a 90 degree V or L twin achieves perfect primary balance and powerful because the stroke is less than the bore diameter (over square). These V or L twins are commonly referred to as Crotch Rockets. Harley Davidson uses one of the worst and most inefficient designs, that being a push rod, 45 degree V with a stroke longer than the bore diameter (under square), take that along with large displacement and you have an engine design that will self destruct at anything over 6000 rpm. Those V Twins are commonly referred to as Crotch Tractors. ;)
In addition to the wankel rotary engine many have mentioned, there is also the rotary piston engine. Think of a boxer engine, but with 3 to 6 cylinders spaced evenly around the crankshaft, which has only one crank throw with an unusual connecting rod setup. They are popular in airplanes due to efficient air cooling, but there have been a few bikes with them.
Then you have the Honda V3 and V5 race bikes. Having an odd number of cylinders allowed the engine to be narrower between the rider's knees while cramming in as many cylinders as they could. There is also the Horex VR6 engine which has such a narrow vee angle that it only uses one head. This configuration yields an engine that isn't as long as an inline six or as wide as a V6. Basically it allows you to put a 6 cylinder in the same space as a typical 4 cylinder. They also sound amazing! The only real downside is that the cylinder head is very complicated and can sometimes have sealing issues.
the rotary piston engine you speak of is called a raidial engine.
@@XchanelgamersHD Radial! I knew there was another name for it, but I couldn't remember. Thanks!
Needs a propeller to help I move.
ktm / husqvarna did a great job adding a second balancer shaft on the 690 in 2017. I bought the ktm 690 smc 19' and love it. can't wait for spring
So many misconceptions in one video.
A few:
1. Max torque depends on one thing really: displacement. Harley Davidson V2s are among the worst engines when it comes to torque/displacement ratio. Sportbikes are the best (just do the calculations). With lower torque it may be easier to get better torque (and power) at lower rpms, and that may be what confuses people about torque.
2. The lean angle on BMW boxers are never (well, I don't know about the 1200C models) limited by the cylinder heads. It might appear so but is is the footpins, central stand or. sometimes, the exhaust system that limit lean angle. For the R1X00GS models it's the footpegs. I think this is true even for the GSA models with the construction scaffolding added around the cylinders.
3. When you compare six cylinder inline engines, do not mention the Honda CBX in the same sentence as BMW K1600 other than for educating purposes. The Honda CBX is almost wider than it's long due to the engine. The CBX engine is ridiculously wide and on top of it they added some generator or something at the ends. The BMW K1600 is narrower than the four cylinder K1200 engine that preceded it and could probably power a sportsbike without appearing ridiculously wide. Almost.
"The CBX engine is ridiculously wide and on top of it they added some generator or something at the ends". INCORRECT
only Honda's 4 cylinder engines of that time had an AC generator and a "something" on the end of their cranks. I do agree that the two bikes are very different what with the BMW having a 31 year tech. advantage. It seems to me that some people look back a little too favorably on those old CBX as the bikes did have their problems. Among those being that little issue of the con rods exiting the engine.
Also Engine torque =/= rear wheel torque. It's also all about gearing
I was just talking to one of my friends about the boxer he's thinking of getting himself a GS adventure 1250

I'm curious about your opinion on the horizontal Vtwin- MotoGuzzi style motor. Thoughts?
7:00 I have to agree about the Triple being the best of all worlds. I moved up to a Tracer 9 GT & the triple engine is smooth, powerful, torquey & has great gas mileage. I'm hooked.
Whats up with the unrelated stock footage in your videos ?
One MAJOR point was missed with the boxer engines (since I ride a boxer BMW): torque output is nearly maxed almost ALL rpm range! Also their very low center of gravity makes them very easy to handle. Makes it a great touring bike where you can pack half your house on it .. oh and don't forget your wife! Honda Goldwings also use these engines because of the same reason and just remember what Jay Leno said: "Horsepower sells a vehicle, but torque always wins a race".
A thumbs up 👍 for the V Twin Ducati. Took a while to get used to but I’m in love 🥰
I watch tons of moto vids. I must say, I like yours the best because your so darn entertaining. Keep em comin.
V- twin
Pros: Ducati uses it
Cons: Harley Davidson uses it.
*Perfect*
Ducati and Suzuki use a 90 degree v twin design , Harley doesn't, big difference. Very smooth design with no counterbalances needed. The Suzuki SV 650 v twin is a great bike at a great price. Yes , I own one!
@@kirarittberg5088 did you even watch the video ?
Yammie left out Aprilia on who uses V-Twins

Great v twins
@@kirarittberg5088 The differences between a Ducati V-twin and a HD V-twin go much deeper than cylinder angle.
It's basically like comparing a Ferrari V8 to a Ford Crown Victoria V8.

Boxers come in 2, 4 & **6** cylinder arrangements.
Awesome video ........how about Guzzi's V Twin mounted sideways ,rotary engines and factory turbo's from the late 80's (engines that failed in bikes segment?). Also how about a similar segment on primary drive methods e.g. belt versus chain versus shaft and the pro n cons of each.

How would you not consider sound as a pro in the Inline 6 engines?
I own a '98 Honda Valkyrie with 6 into 6 after market exhaust and it sounds so sweet when wound up...like a 6 cylinder race car. I love the sound.
What’s with this title ? I thought this video is all about that upcoming hideous BMW Cruiser !
7:24 The best way to balance out a 900cc inline triple is add an opposing 900cc triple set of cylinders. With a power stroke every 120...... WAIT, OH YEAH! That would be a Valkyrie engine.
I mean, nobody -needs- six cylinders to move big bikes. But it's smooth bruh. Real smooth.
I want to see some of the crazy engines, like the V8s and rotaries.
Rotarys are a fucking thing
8v have been done several times, most well known Boshog if I recall correctly.
Thomas LeMay even moto guzzi built a 500cc v8 motorcycle
The only production V8 i can think of is the Morbidelli 850
Yes. There should be a video on the craziest and most baller engines out there. Factory, or aftermarket.
you are way too caught up in hp. not everyone that rides wants to break the sound barrier.
what about Moto Guzzi with their version of v-twin (kinda almost v-twin boxer)
I always thought of the Guzzi as a bent boxer
90 degree v decent power and great torque
Honda also built the liquid cooled 500cc v twin mounted just like the Motoguzzi.
@@theoldman8877 Indeed! That Honda model (IIRC it was something like CR-X ?) is the only other transverse-v I've ever seen - not nearly as pretty as the Guzzi tho...
The Moto Guzzi is a boxer twin with perky.......cylinders.

Wow... there are a suprising number of vocal Guzzisti in here. Although... Notably an Italian inspiration. I love my Nevada. I also love my R75, which made me frown when I saw the clickbait.
BMW has been putting opposed engines in their motorcycles since 1923. What could they possibly know ? This guy gets off on listening to himself rattle off a bunch of specs like he's some kind of m/c guru..............
The moto Guzzi transverse v twin is amazing as well. Vibrates a lot but ton of character
I use a -2 in line configuration, yes, a negative twin!!!!
I love in-line 3-cylinders, but is it true that they get better gas mileage? By the specs, a lot of 2020 in-line 4's claim higher gas mileage. Are they fudging the numbers?
You left out the cross-plane crank 3 in the MT-09.
Couldn’t get comfortable on the V4 Honda Magna, but that engine ... multiple personalities ... one minute=cruiser; keep twisting the throttle=beast.

there not, had one and it was good.
Everyone just waiting for that triumph street triple / daytona love from Yammi Noob.
6 mins 34 seconds of waiting and wasn't disappointed !!
Worth noting that some of the modern parallel twins have a "dead" 3rd cylinder that is just a counter weight.
A good example is the 800cc BMW twin. They wanted to retain the firing order and smoothness of their opposed twin. Solution, make both pistons go up and down together and have a counter weight that run opposite between them. Since both pistons hit TDC together, the smooth 360 degree firing is retained, and there is virtually no vibration.
I recently moved from the DFW TX area to northern NJ. Most of the roads around here are 45 mph and lined with trees. I would have never thought I'd own less than a 1000 CCs again, but up here, a smaller bike makes a ton of sense. A great deal came up on an F800GT, it was great fun on the roads around here, so I bought it. I was pretty amazed how much this motor did feel like the older opposed twins.
Back in 70's a R100S won the Castrol six hour race outright against 1000 cc Japanese,4 cylinder bikes.
90° V twin aren't unbalanced.
If their not 90°, it requires a balance shaft, or it's a Harley.
Same story for the V8. And I think the V12. That is why those are so popular: they are faster because they have no extra weight rotating to correct unbalance. Opening the throttle, you do not want extra rotating weight. Simple.
First I thougt the 90° V4 and V6 are balanced too, but that is wrong. Perhaps a 2 stroke V6 would... Check it yourself! Just like those crossplane crankcases, it is all about torque and power delivery, all engines are different. Just ride the Kawasaki ER or Versys 180° twin. And compare it to the Yamaha MT-07 270° twin. Both very good, and so different. Before you buy a parallel twin, you'd better know how many degrees are involved. Or simply ride it and feel if you like it. I was kind of addicted to the TDM 900, a tourer 270° twin. Now it's a single piston for me.
@@voornaam3191
Keller is working on an 90° V3, which uses one 320 cc piston opposite two 165 cc slugs, using a "big bang" firing order. His goal is a balanced, smaller package that has the positive attributes of the inline 3,4 and the V twin.
Anyone interested in 14,000 rpm and low end torque?
@@johntempest267 Great idea. That big bang firing order really works.
I've been thinking about modifying a V engine, usually it is a 270° firing order, but you could turn the camshafts, adjust the ignition and make it a 90° firing order. Like the big bang.
You might need a stronger clutch and all. Or limit the revs, to keep everything standard and still get that big bang feeling.
But actually doing, well, not enough guts for it. It might cost me a bike. And I have no spare money available. But it might be a funny project...
Just think about it, for a parallel twin you'd need new modified camshafts. You need tools for that, suppose you could get camshafts for machining your own design of cams. But for a V twin, you have two sets of camshafts and a chain. That way adjusting the valves for ignition 90° after the other cilinder is easy. But if there are balance shafts, things get complicated. So you absolutely need a proper 90° twin, a 70° twin (like in Honda Transalp) is more complicated, I'd ruin its balance.
@@voornaam3191
Having access to state of the art 3d printers and Clemson University's super computer is helpful.
This motor exists as a mock up and digital virtual at present. Casts for the cases is complete.
Last I heard, they're tweaking the crankshaft to try various stroke length combinations to get harmonic characteristics ironed out. It's amazing this can be done virtually.
This obviously will affect displacement, so he says it's a 600 to 650 cc design.
All of this is way above my pay grade, but (as a SV 650 pilot) it fascinates me.
Could we get some more vids of you off-roading?

What do you say about cbr 650 rr?
For me I want to know about bearings. When you have a twin like a Yamaha xs 650 you can ride the cam on six ball bearings . When you have a inline four the cam runs on the head without even babitt bearings. I like the center of gravity low so give me a pushrod engine.
On my NC700X the twin cylinders are tilted forward and there's only a single cam for the 8 valves. With the gas tank under the seat it makes for a nice, low CG.
another huge advantage of boxers is they are way more serviceable, valve clearance adjustment or plug replacement, i.e. are way easier to do. In my current 4l engine bike, replacing the spark plugs is a pain in the arse, it takes me over an hour, in a boxer engine that would take 10 minutes tops.
Yo, Yammie.... you missed a couple of points about the inline 6 configuration, ie that 1, the engine is perfectly balanced therefore will not find a better type for smoothness, but more importantly 2, the SOUND of an inline 6.... which is a truly sensual sound to any sort of petrolhead.
CLICKBAIT you never spoke about the “big boxer” that you pictured????
