This channel inspired me to drop my career in health insurance to pursue a mechanical engineering degree 3 years ago. I’ve never looked back. I’ll send you a thank you card when I graduate in a year. Thanks RF9
Until you realize how much the starting pay for a BS in Mech E compared to actuarial science. You can make more money on tik tok videos than studying engineering. The world is topsy turvy.
That's some good stuff man more power to you
@@ronaldm4392 Are you saying the starting pay for a BS in Mechanical engineering is not much?
Congrats man! I’m a junior right now in Mech E too and am ready to get out 😂
Salute!
As a mechanical engineer I love to see how clearly and concisely you explained all those material properties. Well done!
It's honestly amazing how he is able to explain those things in the simplest language. He forgoes just the right amount of details so it is understandable by laymen but still accurate enough.
This video was like sitting through a condensed and interesting version of my aviation mechanic trade school all over again, very much agreed that it's an excellent watch.
p.s. copper grease all the threads and go slightly easier when tightening up
I like to see all that stuff as a regular dickhead as well tbh.
Yeah actually. This was a semester worth of machine design in 10 minutes.
He just explained several engineering classes in 10 minutes lol
When a channel can get motorcycle enthusiasts to watch a video on metallurgy, there’s more to that channel than just motorcycle videos. This channel never disappoints.
This channel about motorcycles got me, a guy who doesn't care about motorcycles, to watch a video about metallurgy. I just love how they can bring this absurdly high quality and outdo themselves everytime. Never ever missed a video.
It is a safe space for steel. And cast iron. I am ok with both.
I have no specific interest in motorcycles, but the Smart Helmet video brought me here, and I subscribed right here. This channel is great.
This, engineering explained, and driving 4 answers.
Best channels on UA-cam.
Metallurgical Engineer here. I'm glad for everything you've put up, from beginning to end. There is so much to be said regarding why steel is a great engineering material, and we often forget the many reasons (and perks) why.
Steel is real
As a fresh metallurgist/ material engineer I can say you explain the subject better than most of the instructor at universities.
Was thinking the same thing, and he answered pretty much all the questions I've had for a while, while he was at it.
If only professors would use real world examples instead of only delving into abstract theoretical gibberish all the time. Aerospace engineer here. You would be surprised at how many things I learned for real AFTER I got out of college and had to deal with the real world.
@@flechette3782 absent minded professors
If all education topics had an internet parallel where related UA-cam videos and other internet posts were linked, a lot of it would outcompete most teachers.
But instead internet education is just more copyrighted-protected self-published content, rather than a consolidation of what's already out there.
I'm a knifemaker / bladesmith and agree 100% with you!
"I am the monster,not for creating this 45 year old steel that cost 500$...... but for helping create a world that asks for more."
We deffinatelly ask for more!Well done brother.
I would love if there was a kit with the subassemblies like in the video with the engine as one, exhaust, suspension, frame, tires, wires, tank, guages, brakes, and so on. It would be cool to be able to put together a kit like that and save a bunch of money in the process. Maybe something like a cheap honda 350cc single cylinder as the engine.
@@charliemaybe Totally agree! I've been searching and searching for a beginner bike build kit and can't seem to find one.
@@experienceforge You run into problems with it if you want to make it modular. cant have the same frame for multiple engines, because you need to align the engine to the rear bracket. Also producing multiple sizes of engine becomes expensive quick, so no one is making the kit because its not profitable. I say the best thing to if you want to build a bike is to build a "cafe racer" or "scrambler" type of thing from an old carbed motorcycle. Stripped down basic mechanics, minimal electronics. You can make a dirt bike, scrambler, cafe, even faired bike if you want to mess around with fiberglass. Take everything apart, remove everything thats not essential and build it back together.
I am wondering if he means that he is a monster for creating a world that asks for more ( more bikes like this one) or (more advanced bikes even though it is not neccessary)....
Because in one way or another he does both and maybe I missed something because english is not my first language
@@experienceforge The thing is there's a lot of precision involved in a motorcycle. It's dubious enough with a car, and there have been "kits" for those that didn't require a bunch of knowledge and/or learning along the way...
BUT with motorcycles, because they utilize the gyroscopic effect and depend so much on alignments and balance and so forth, even at the factories, there's a fair amount of micro-adjustments that have to be made to fit each component to the greater system...
You're going to have to start relatively simple on something relatively forgiving, like an older and smaller cc carb'ed bike or two, and work together the cafe racer or scrambler from what you can find in scrap yards, garage and barn finds and then of course, shops. As you learn more about the inner tinkerings, you can get more advanced.
There just isn't profit in something as dubiously complicated AND precise as a motorcycle when you consider the variations a public market is going to demand. The least bit out of alignment between engine and wheels and you have a bike severely "right handed" or "left handed" making it tricky and dangerous because leaning one direction pivots you right around at speed, and the other way barely does anything...
Many of us started on mini-bikes with a welded steel frame and a Briggs and Stratton or Tecumpseh 5 HP engine mounted on them... and then got out welders and angle grinders and went about "customizing" them, which was as frequently PHENOMENAL as it was "A TERRIFYING MISTAKE"... BUT you live and you learn (hopefully)... ;o)
Hi Ryan, I am a mechanical engineer that practiced for over 30 years in aerospace. You have all my respect for explaining those important concepts in understandable ways. I wish I had started my degree with this video 👍🏻
Hehe, I didn’t understand
"I am the monster, not for creating this 45 year old steel that cost 500$...... but for helping create a world that asks for more." this is by far one of the finest videos I've seen. matter of fact even the previous top gear can't reached this level. daaamn son you deserve an Oscar Well done
The point is that Top Gear guys had to learn the text by heart, and this guy seems to know exactly what he is talking about 🙂 Very well done, as usual
Top Gear are entertainers making entertainment. Fortnine is a physicist making sense of a topic that is close to his heart. A long long shot from the Top Gear pulp.
The motorcycling physicist is going crazy with the upload schedule.
We'll take anything
That’s the “Artistic Motorcycling Physicist” I think. You need to get his degrees in a row! Les in UK
That's what happens when sponsors knock on your door and offer you the dollar.
Einstein said: "If you can't explain it simply, you don't understand it well enough", so clearly Ryan has mastery of the subject matter of every damn video he's ever made. Another entertaining, perfectly clear, succinct explanation of an interesting topic.
This...
Einstein would subscribe. 👍
I am Einstein, and I approve this message.
@@bendgeddes This is actually pretty interesting, I also really believe he would!
This is only channel on YT with comments this awesome.
Ryan, in case no one’s said it outright: if baked in sponsor spots are what allows you to make videos, they are absolutely worth it. No other channel’s uploads get me as excited to watch as yours do. Plus now I have a new razor to try out.
Even the ads are a good watch!
and the sense of humour!. Watching a guy with a money-counting machine while Ryan was introducing the new razor was hilarious!
Yep, me too! Or in 16-21 days, anyway.
The advert progress bar makes it fine to watch too.
also, it's an ad for something guys interested in motorcycles actually could like - not some random mobile game.
As having been a materials/metallurgical engineer, LOVED this. Some 30 years ago had similar discussions with friends that raced bicycles. Aluminum matrix (once a thing) & carbon frames very brittle & even caused more injury to riders than just road rash. And these materials were not repairable--so if you can't afford new frames if you crash, steel often a better option. Similar for motor bikes--steel easier to repair or modify anywhere. But options are great that filter down from racing--where weight and performance are super critical--down to bragging rights for regular folk...
It's scary how good Ryan's videos are
I don't know what's better, the production quality or the research. Both are top notch.
He could easily sell these to some streaming network, but instead we get it here, on youtube, for free. Pretty damn awesome.
Like Jermey Clarkson, but with motorcycles :)
You do know he isn’t the one making them…he narrates/acts…but he’s not producing.
@@user-yi3ox8wy4k If it ain't on the page, it ain't on the stage.
Why is it that one guy on UA-cam and his small team produces a more captivating and informative 10 minute video than all of Hollywood can in 2 hours?
Knowledge + Passion + Communication skills > greed
Being authentic will always produce something of value that lasts.
@@MichaelPohoreski That's some wisdom right there.
Inspiration and passion.
Because he is A L I V E
Vice grip garage is similar
Man. As an engineer and a motorcycle enthusiast. I'm so glad the direction this channel is headed
Just here to echo literally every other comment, by saying"Thank you! " for giving us the best motorcycle content on the web. Team Fortnine is on a different level! It feels like you're tricking my brain into learning effortlessly. Production values are through the roof, yet somehow constantly improving.
Thanks so much!
Boo! What colour(s) should we paint it?
I'm a fan of the old school Kawasaki red. My girlfriend picked up a 50th anniversary Z650 this year and it looks fucking sweet.
Anything but hot pink simply won't do
Yellow and black
A light blue would be, spooky…
white frame lime green tank and fairings
This channel is the ultimate instaclick for me. I had no idea someone could trigger an emotional response over helmet reviews or whatever this new video is about. Yep, I'm already feeling it before I've actually watched it. Talk about conditioning your audience!
I guess what I mean is thank you.
Yes, perfectly stated - I think Ryan's videos are the only ones on UA-cam that I click on without any prior interest in the material.
Love how you managed to make a non Halloween subject into an interesting themed release, nice breeze of fresh air from the Halloween specific specials most put out
Automotive metallurgist here, and maybe 90% of my work is in gasoline engines and fasteners, so this is very relevant to my interests! A few updates in automotive metallurgy: You quote the yield strength of steel fasteners at 800 MPa, but for an exposed fastener, we can now safely use a metric property class 12.9U (austempered/bainitic) with a dip-spin or spray applied zinc flake anticorrosion coating (such as Magni 565) with a yield strength of approximately 1100 MPa. Yield strengths much higher than that are possible with steel fasteners (such as PC15.9U around 1350 MPa) but those are for use inside sealed powertrain components like engines and transmissions where we don't have to worry about hydrogen embrittlement from road salt and acid rain. Second big update: After decades of trying to perfect Nikasil spray coatings and Alusil aluminum castings with silicon matrix bearing surfaces, the automotive industry has all started moving to a new engine block technology that finally outperforms iron blocks and iron liners: Ultra-thin steel liners sprayed in molten form onto the bores of aluminum blocks. Turns out, it actually reduces galling, abrasive wear, and friction losses over iron bores while increasing cooling rate, reducing hot spots, and allowing higher compression/boost without detonation. I expect we'll see this all over the motorcycle industry within 5 years.
I recently graduated with my Mech E degree, so my theory is good, but practical application knowledge, lacking. This was one of your most satisfying videos because I understood the science and saw the application. 10/10 video again
As a Mechanical Engineer with a M.Eng. degree, I have to confess due to the particularities of my job I find my extensive hobby work in fabrication across a broad spectrum of fields is a skill set that I use more so than the teachings of the degrees themselves. As one of my professors told me long ago, the program teaches you how to think and learn as its primary skill set.
This makes me love and appreciate my and other bikes more. The amount of thought and expertise that goes into choice of metal is something I never even thought of. So cool. Ryan and the team are the only ones that can combine engineering, metallurgy, motorcycling and halloween in one video and have the result come out fascinating.
True. The video is so good I almost thought about switching to the single blade razor company that sponsored the video, even though I'm a Gillette five blade man. Maybe I even should?
@@raylopez99 😆
Only Ryan could make an ad as enjoyable as the rest of the video.
The next time someone asks me about mechanical properties I am going to make them sit down and watch this video three times. There was a LOT of great factual information packed into this 10:02 minutes of video. You could literally stop it every minute and have a 2 hour lecture on what you just mentioned. LOVE it.
You can click any video on UA-cam and possibly hear something you've never heard before. You watch FN's videos because you know you'll learn something you've never tried to understand before. Beautifully delivered.
There is no one on UA-cam that even comes close to Ryan's videos. He sets the bar so high that most youtubers don't even know it's there.
I can confirm, and totally agree. I am a lifelong motorcyclist and I make vids about restoring old fighter jet engines. I bow at the altar of Fortnine, for I am not worthy!
Ryan's videos are the best I know of, in any subject or category.
It’s odd how good his videos are you’d never expect it from a motorbike UA-camr
You posted this comment 3 minutes after the video was released. Stop d riding for likes.
@@j1j1j1j1j1 he could have watched the first few minutes/been a viewer for a while? No need to get toxic.
No argument, Ryan is epic. Do you subscribe to "Bart?" He's actually been stepping up his game pretty good. Nice personality and seems to have pretty good integrity. More into the history than the science and physics where Ryan reigns Supreme though.
You are an excellent communicator. You really have a knack for making potentially hard to understand subjects accessible and entertaining at the same time.
He's like the NDT of motorcycles
Fantastic stuff here Ryan. I work on aircraft and it's a huge mix of different metals for different applications down to a science. Love to see it explained here clear and concisely.
I always end up watching your videos multiple times. The way you explain everything so clearly and concisely really isn't what compels me to rewatch, because I don't need to in order to fully understand what's been said. What is extremely satisfying though is the production quality and the INSANE attention to detail. Amazing cinematography, stellar lighting, witty script-writing full of character, and of course this time of year the spooky Halloween touch. Once again, I am handsomely rewarded by my decision to subscribe. Bravo.
He explains everything so well.
The only thing I wish that he would do more is explain the equations on the board.
Fascinating. Just last weekend I discussed with a friend why motorcycles are all so heavy and whether a little more expensive materials wouldn't make them significantly lighter. Now I see there were a lot more variables to the equation we didn't have on our list and it is not just price pressure making manufacturers choose predominantly steel.
carbon is the answer, but it's not easy! (or cheap)
Yes, video is great, but i am amazed how seamlessly incorporated that advertisement was. I can't remember when was the last time i didn't skip commercial. Great job guys!
That steel never fatigues is one of those things we take for granted but is a completely understated pillar of modernity. It's like the properties of water that make life possible, steel makes (modern) life possible.
Thank you for getting me into motorcycling. Commuting on two wheels has literally changed my life
Two videos in a week? We’ve been blessed
I’ve been watching F9 for years and I’ve never seen a video so accurately done in terms of material science. I’m in my second year of Mechatronics Engineering and you described all the concepts flawlessly!
Stellar production as always! You have a gift for explaining technical topics to laypeople without talking down, cheers!
Beautifully creative and informative.
The effort the F9 team put into these vids does not go unnoticed.
I dont have a motorcycle myself yet, but the cinematography and how you deliver information, it's all really good quality, and it keeps me coming back for more
when you get your first, it's not like riding a bike (bicycle) [well] get a small dirt bike, it is[n't], the same. A bicycle you push the left handle forward to turn right (think about it). A dirt bike, you push the left handle forward to turn right, but at higher speeds. A street bike, you push the left handle foreword to turn left (and the heavier the bike fells in a corner, the more gas you give it, or battle the weight) A street bike, you don't pull the handle. You'll kill yourself.
Side note: if Ryan stands behind a sponsor, it's definitely worth a look
I have had the Henson razor for a while and it does work very well
Another owner here, it's an excellent razor highly recommend
While I've never used that brand, I do use old fashioned safety razors, and just from seeing them in the video I'm confident they're better than anything Gillette makes.
Dude. How do you know SO MUCH about ENGINEERING, while also knowing SO MUCH about art, literature, culture, and history, AND be able to present your thesis so clearly and cleverly? GENIUS!
Ryan is one of the most intelligent, if not the single most intelligent people on UA-cam, across all the car and motorcycle channels. And that's saying a lot, because there's some serious geniuses. But I feel like Ryan knows a lot about everything, not a little about everything. He's a rare... What's that word they used to use? People like Nikola Tesla, and the original engineers who knew about everything. Today it's strongly discouraged to know too much stuff, the school system wants you to only know about one thing, which is why people don't have common sense or a wide variety of engineering knowledge.
One of the highest quality UA-cam channels in existence
Inarguably the best motorcycle content on the internet. Congratulations Team F9, you never cease to amaze.
I almost didn't watch due to the title seeming a bit boring... then I reminded myself that this is F9. Watched, liked, still haven't been let down. Thank you!
I don't come to this channel to just learn more about motorcycles...I come to this channel to witness art! The production is just * chef's kiss *
Love the content Ryan, as a 3-decade cycle guy and Trials lover you do such great work!
As an industrial designer I can confirm that the knowledge in this video was as intense and concentrated as the amount of sugar in a soda can!!!
I will watch this man review a blender. The pinnacle of motorcycle content
youve been poping up and down on my recomended, never subscrived, until now, as a Masters student in engineering i can tell you this was the fastest and one of the best classes in material selection i've ever had
You nailed this. More insight in your UA-cam video than in my Mechanical Engineering education.
New FortNine?? Yes!!
Lost for words! Every video, without fail, is a masterpiece of cinematography, content, and entertainment! What I learn from this channel outstrips any other media I watch. Great work again ... and last time ... and the time before ... and!!!
Ryan is amazing. He called back to the hockey scene he played right before speaking with "what’s annoying at the blue line is fatal at the red line", which is also a double entendre.
In hockey, the blue line of the opponent is frequently where offsides is called meaning it can be annoying. But the red line signifies crossing into enemy territory, meaning it’s more dangerous, and if the defense does not do their job, can result in a fatal blow.
Of course the other meaning is that the motorcycle pushed to the red line is alluding to motogp as previously mentioned.
Cheers, Ryan❤
This is absolutely top shelf content. Every damn time. If you can find anything better produced on the platform, you're probably wrong.
Aerospace/mech eng student speaking here: your ability to meaningfully communicate tough concepts is so admirable and refreshing.
The writing is exquisite as always. The story telling is so efficient -using hammer sounds synced with the bending of the forged rod absolutely communicated how forging/toughening is accomplished without ever having to verbally describe the process.
As someone who's equally passionate about engineering design and visual storytelling, I have such appreciation for your thoughtfully constructed, fantastically educational work. Nevermind the Halloween visual motif and the syncronized late release time.
Koodos to all involved.
It's a joy to learn something new, and even more so to feel things that have previously been confusing or obtuse come into clarity. You routinely tie information to application; in other words, you communicate both new knowledge and how it's used. and that makes those new facts feel like you're sharing them with me. Like offering a fishing pole with a fishing lesson. It's like offering me an opportunity to see the world for myself, and make it my own.
As a life long fan of education and writing, and as relatively new fan of motorcycles: thank you for your years of work.
I've always thought of my bikes as a collection of parts that creates the whole. Having done a fair bit of wrenching and rebuilding of bikes myself, this video made me realize that I rarely question the materials that parts are made from. My main focus is usually the 3 'F's, form, fit & function. Unlike the adage about how sausage is made, I DO care and want to know what goes into creating my motorcycles. Thanks, Ryan & team for another fantastic episode of NOVA on motorcycles!
I appreciate the way you guys have integrated the advertisements. I can watch it if it's something I'm interested in, but I can skip ahead with precision if it's something I'm not.
Always excellent content. 💪🏼
Fortnine tossing around more knowledge is always cool.
the first time I've actually sat through a mid content add roll in ages. Well done!
I love how your videos are both entertaining and educational. Well done as always. Keep up the great work.
Absolutely brilliant episode! Everything from information presentation, photography, sound; mood, humor! Simply LOVE IT! My hat down to the team.
My friends and I would always debate what frames are better on our dirt bikes. Always the Yamaha steel frames vs Honda aluminum frames. Thanks for clearing up the differences. Also you inspired me to start my own channel and work on dirt bikes, atvs, motorcycles. Thanks
Once again, fantastic in every regard already described!! As an athletic trainer and health educator with 21+ years working in outpatient physical therapy, I’m happy to see Ryan returned physical health and fitness.
One of the best videos yet. Absolutely brilliant combination of information and entertainment (as per usual) 😊
...the dude counting money in the background during the sponsor part... man, these guys' humor is incredible :)
Such great content. I love the nerdy side to your work, it’s nice to know the how’s and why’s. The art direction is also routinely as good as it gets. Thanks for all the teams effort! Your inspiration for me to finally learn to ride at 50. Yes groan away!!! Let age be no barrier, we all, through the grace of god, get their eventually! Thanks again.
This video helped me understand metal properties in 10 minutes than my entire welding school for one year
Also, it blows my mind with how top notch the quality of your content is, how it's meant for motorcyclists but even interests non-cyclists like myself that you "only" have 1.6 million subs... This has been a 10 million+ quality channel for a long time, is motorcycling THAT niche of a topic?
I’ve been a tech for 22 years and I gotta give a nod to your ability to convey complex ideas to total laymen. As always it’s a delight to watch your videos.
Absolutely one of the finest videos you and your team have made.
Another gem of knowledge. I'd like to hear more on one area, the galvanic issues with stainless steel fasteners and other various metals. Regardless, even the sponsor portions are well done, so even the advertisements aren't horrible.
Keep going.
Huh. After so many years of watching youtube, finally a sponsor for a video that I actually kind of want to buy.
I learned the hard way to NEVER use stainless steel on exhaust headers, or any hot component. At high temperatures, the chromium can slowly defuse in to the nearby mild steel and essentially solder itself in to place. Requiring everything to be drilled out and helicoiled. Stainless fasteners also don’t like impact guns. While building a rear rack, 2 sets ended up seizing half way through the threads.
It's not just heat that fuses stainless fasteners to stainless parts but also shocks/vibrations through galling (cold welding). The rule in mechanical assembly is to use dissimilar metals (it can both be stainless steel but then you need an austenitic and a martensitic one). Using helicoil is a good practice and not just for repair. In the space industry, we use stainless helicoils on aluminum parts which are then bolted with titanium bolts covered in MoS2 (it helps against galvanic corrosion by decreasing the potential difference between titanium and aluminium). For stainless steel parts that need stainless steel bolts, we use silicon bronze helicoils. Impact guns are a big no no and more like a last ditch effort for loosening a heavily rusted bolt.
You can spray everything with copper spray. I am pretty sure that's the way to fix the problem. They also sell copper paste that you coat the entire bolt. Or if it's a low strength application, just coat the entire bolt in teflon pipe compound rated for 500F and oil and gas resistant. They also make high temperature thread lockers. Thread locker forms an insulating barrier of plastic between parts, preventing corrosion.
Great job on your research. That's a lot of legit engineering explained clearly and concisely!
I'm confused. Google says titanium is like steel in the fatigue limit area. That's just question, not any sort of criticism, BTW. I freaking love your videos, man. Seriously, this is some of the best content available.
This is a perfect 10-minute overview/refresher on materials engineering. Well done!
You guys are the pinnacle of motorcycle content on UA-cam. Thank you guys for that and keep up the great work!
Purely brilliant! I enjoyed every minute. Even the ad break
The way you explain things makes concepts click in my brain that I have struggled to understand for years. My husband can explain something to me 10 times and I’ll watch a 10min Fortnine video and understand it instantly. Thank you 🙏🏻
Your explanation of the reasons various metals and materials is top notch. I think this video would be good to have in a materials science course! Awesome video!
Another masterpiece. Clear, concise, and very informative.
Motorcycle content doesn't get better than this!
I think this is your best, most instructive video. Really changed the way I see a lot of things...
This channel is legit - you just earned yourself a subscriber. Love it. Keep up the great work, guys.
my brain melts when i try to figure out how you put this all together. goddammit Ryan youve done it again. Fort nine for president.
This is for sure the weirdest take on a Halloween special I've seen so far.
It going to be strange for anyone who watches it later, not knowing what date it was released
What a fantastic video! The cinematography was amazing, and so informative too
You guys are killing it. Another lesson I didn't know I needed, but glad I got. Cheers!
At 12:08 am, my insomnia is rewarded!!!
Thank the Gods of UA-cam and Canadian moto-journalists!
This channel is so freaking good!
Literally just got out of my mechanical metallurgy class, todays lecture was on material selection and then I get home and see this in my subscriptions feed, likely a repeat of todays lecture. Cost, performance manufacturability, and availability. I’m betting it’s the exact same lecture but in 10 minutes instead of an hour and 15. Gonna have to compare notes after watching lol.
NO WAY I just bought a 1978 KL250 a month ago, never thought I'd see the bike featured on this channel!! thought they were way too obscure! love it!
As a metallurgist.. this video is fun 😊
In high school, my physics teacher discussed the comparison of weight vs strength for steel and aluminum in bicycle frames and speculated that the ideal material might be bone. With the advances we've made in biotech in recent decades, that might actually be feasible to try now.
I think you should revisit the math on that one, I don't think bone is anywhere close to competing with steel.
@@NixodCreations I'm sure you're right, this was in the 90's when chromoly was just becoming common and carbon fiber was exotic. The discussion was just for bicycles which wouldn't generally require the strength of steel, so bone was a bit of a middle ground between steel and aluminum.
@Retired Bore That's pretty cool. Also probably why bamboo has made a resurgence as a renewable building material in recent years.
I'm a metallurgical engineer and notorious pedant. I can only offer you, the research team, and this video the highest praise. "That was pretty good"
I love the filmmaking aspect of your content. I always get impressed by how original your episodes are. Well done! Keep up the good work!
I laughed at the guy counting money in the background of the Ad :D
Edit:
Amazing Video as always. Fort Ninve rules. Thank you for talking about the upgrade crave. Maybe this video will change the mind of some people and the trend goes back to longevity and sturdiness instead of chasing grams of weightsaving you probably dont even notice riding on the street. I love my older bikes and their servicability. You guys were a great positive influence on my riding and bike buying decisions and you continue to be for many people. Thank you for existing
These videos are works of art. It's amazing. I hope you never stop this
Great job RF9 team. I'm a long time adventure biker and engineer, who love's design of anything 'bike'. You've brilliantly introduced the material science behind the toys that dazzle!
My god that was a great watch,i just love this channel,Ryan is the only one that could pull this type of content off,sort of early UK top gear presenters,no one can take there place.Much love from Scotland.
another great video from FortNine. thanks
