Square Four Motocycles !!!

- In this video, you will see interesting motorcycles that are powered by a four-cylinder engine with a square piston arrangement. Throughout the history of motorcycles, the "square four" engine was used in very few motorcycles.
Many thanks to all bikers and motorcycle fans who contributed their videos to our motorcycle channel. If you have a motorcycle at home that you built yourself, or an old, interesting or unusual motorcycle that you would like to show, please send me short videos from your camera or mobile phone to: We Transfer - jawatinomoto@gmail.com
I will process your videos and publish them on our motorcycle UA-cam channel - Jawa Tino
first time seeing the kwacker prototype, thanks
Shame they made the side panel triangular, but it would have been tricky making a square one fit, I suppose.
a reasonable cruiser, with a heat problem built in. i think they started with a 600, maybe oil-cooled?
Loved the Suzuki, so much exhaust smoke it blinded the competition.
I really liked the green Ariel Square Four 1000. The entire bile looked looked bigger and beefier than the average British Motorcycle is it?
Ariel sounds are kind of unique huh? Very cool. I didn’t know the Suzuki was a square four, because I’ve never seen the engine. Great video, always educations, Thanks
Ariel sound, the best!
I just love the sound of the Ariel
👍
G'day Bro.
This was a cool vid ,nice to get a technical breakdown ,
Bike looked pretty nice too ..
Respect
I liked that Kawaka 750 Square four - Never saw one before. I had the original Honda 750/4 - great bike - loved it.
It would have been awesome if they had produced it, but I guess they chose not to compete against their new Z-1 that came out the same year as this prototype.
Excellent, I know of the Ariel square four, but never the other machines.
Thanks for sharing
Always wondered how the Ariel down pipes were connected to the engine block
Loved the Ariel from the first time I ever saw one. All rare, and I'd love to have any of them.
A Suzuki ganhou muita corrida com esse motor!!!
That is an awesome example. Priceless in my opinion. Ariel. Beautiful!🏍💎
👍
Real bikers wear boots and pants Smart ones wear helmets common sense is not that common anymore
Why is it that you need to keep revving the stationary engine, a decent idle is really cool, and a good revving is what's required on the road. Small fingers perhaps ??
Motorbikes have small to no flywheels so there is very little to help them carry the idle as it were, unlike a normal everyday car which has a decent size to smooth out the pulses and the idle. However, both motorbikes and racing cars are designed to be ridden and the latter also has virtually no flywheel so that the engine can rev freely and the response to throttle inputs is almost instantaneous, an important feature in racing. Hope that helps.
The Ariel Square Four, or "Squariel" as it was known, is one of my favourite bikes of the classic British period. My friend production raced a couple of RG500s at a time when it was sold here in Canada, but not south of the border in the US, which should have given Canadian riders an advantage when racing in the US, but it didn't because it turned out that the RG was only mediocre on a test track. No matter, once when a small group of us were out chasing curves in an area I was very familiar with, we traded bikes and I got to ride the RG. It remains the most memorable 45 minute ride of my life. It may not have been a winner on track, but on curvy roads the power, the brakes, and the handling were out of this world at the kinds of speeds that today would lose me my license for many years. And it was comfortable, too !
Oh, you lucky dog!
Edward Turner's square four design was very different to the one shown. His was OHC, iron barrelled and undercooled. This is a 4G, aluminium barrelled and pushrod operated valves. Could be a mk2.
I can't find anything about who redesigned the engine but I suspect Val Page would have been in charge.
One of the sales reps who came to where I worked had an RG500, scary and thirsty bike when it hit the power band.
So many square fours! Had no idea.
Yamaha also made four cylinder two stroke also failed do to emission laws a video on this would be great. Gl750 I believe
Is there an advantage to Ariel's configuration compared the others?
Thanks, I really enjoy the video!!!
Very different motor. Very steam punk looking bike. Cool !
That last bike is rare!
Squar four doesn’t have the original frame I see
Series 2 with a swing arm frame when the last Sq4 was Anstey Link!
interesting video 👍767
Bring back the Square 4s!!!
👍
I was born in 58 as a youngster I remember playing on Dads dead Ariel square four under our house make Brm brm noises.
Awesome, thanks!!
Did the aerial have a problem with the rear two cylinders running hot.
HERMOSA !
I think the original square four was overhead camshaft.
Beautiful Squarial !!!
awesome sound
Noisy valve train. WOW!!
Man sollte das Video unbedingt bis zum Ende ansehen , die Idee von einem schmal bauenden 4 Zylinder Motor ist schön u attraktiv, wir sehen aber, daß sich in Line 4 durchgesetzt hatte .
Bessere Kühlung usw. - anyway ... sehr interessant, schönes Video
Liquid and oil cooling the way to go.
That square fours that Suzuki and Kawasaki made. must have not been a very good motorcycles. because I never heard of any of them winning races. and I've never seen one before.
😂
Lol
Barry Sheene, Schwantz would disagree.
Ariel Square 4 back in the day I got to ride one for five minutes it was a great bike, never could afford one in those days.
I was told they had one draw back! not good for riding in the city as the back cylinders would over heat and seize up. No idea if it was true or not.
Had to jet for it. Had a 1958.
Yes, very true, I had a mate with one back in the 60s and he had lots of trouble with the back cylinders seizing or a partial seize, even when it was going well it was not a fast bike.
@@hullygully1135 Good looks and good sound, though. Produced for 28 years!
Yes, but water cooling would fix that. I heard it was a very smooth bike, and made a great touring bike.
Jim you must see this one
The Yamaha RD500/RZ500 was more of a square ‘V’.
Mechanically awesome stuff but the downright noisiest mechanical moving parts inside them especially being they used straight cut gears to conjoin the 2 crankshafts together. Definitely not the best solution for coupling but I guess when it comes down to space gear drive is the way to go, just don't understand why they wouldn't have used angle cut teeth over straight? Just in surface area and noise reduction alone the difference is superior in contrast. Otherwise everything else is pretty cool to see how they run!
But then you have big end loads and need some sort of thrust bearing = weight.
Also overlooked, these 2T square fours fire as twins, the continuous power with 90° firing intervals was almost unrideable by continuously unsticking the rear tyre.
The reason for 4 cyl 2T's was port area vs swept volume to give best engine breathing, without the regs they'd have been doing 6's and 8's.
Honda went further and made "Drone" engines with all the firing pulses within 65° ~ 70° to help with tyre traction. Good for over 200hp.

Fast Skeeter sprayers.
I would like to,know what chassis that first Square Four was built on. No original Square Four ever had a swing arm.
The first Ariel Square Four before it was redesigned was meant to go into the Ariel 250 frame. The frame was too small and flimsy so they put it in the slow / 500 frame instead. There are two prototype Square force in swingarms and the National Motorcycle Museum. My uncle rode around one of his buddies had an iron Barrel Square for and it sees so hard in the back cylinders it broke both connecting rods. Aluminum head for pipe model with better in that regard but I don't know how much
Though very special indeed, there is also something called " sound experience"....and for me the 4-stroke 4-square sounds really terrible. Almost the same as the early flat 4 engines, as they came in the Goldwing, back in the day.
Gold wing was water cooled!

Why uploading all the same stuff all over again?
Most of these clips were already in at least 20 previous videos.

11:41 A disgusting photoshopping!
05:15 Er jagt da 100 mal den Motor hoch und meint er hätte Ahnung. 🙂
That engine is real ugly
😂
Sorry, my friend... But the only REAL MOTORCYCLE of the batch is the Ariel Square Four. The other modern "thingies" just for racing and "sewing" machine lovers... Keep on with the real oldies!
Good looks and good sound! Produced for 28 years!
