It's genius creativity like this that makes this channel such a treasure.
That bit had me genuinely laugh out loud
I never thought our political plight south of your border could be compared to the international combustion engine, but I haven't laughed so hard at a RUclips video in ages. The perfect end to a fascinating dive into unusual engine designs.
Same🤣🤣🤣
This channel is so damn good.
Heh. International Combustion Engine, heh..
So weird hearing "south of the border" and the context not be talking about Mexico lol
I want a Benz bike.
Same here. I had to go back and play that segment for my wife. She laughed just as hard.
Educational and hysterical... You guys never disappoint !!

I see what you did there, very nice 👉😏👉🔥

Big Tech is watching you.
Puch motorcycles were made in Austria. Here you can still see them every sunny Sunday. Spare parts are available and you can get running bikes for relatively little money. Lots of them have survived over the years due to a vivid fanbase. Very informative and funny video, as always!
My first moped was a Puch VS50. 😍
Out of interest, how should we pronounce Puch?
Is it like “Puk” or “Push”?
@@Pikestnt There is no equivalent for the german "ch" in english, but it comes close to pronounce "Loch Ness". So it´s more like "Puk" but you have to squeeze some air out to make the "k" softer. Hope this helps. ;) Puch still makes bicycles by the way. But I think they were sold to Piaggio, which is the mother of the legendary Vespa scooter. ;)
@@richmotion Thanks. It seems that I’ve been pronouncing it wrong for 42 years 😀
It’s never too late to learn
Thanks again
Saw 3 of them going up the Grossglockner pass this year, must be fun on the hairpins. Going back through France in one of the small towns there was one towing another along the road. A lot of them on the roads and even dealers selling them.
By the way the founder of Puch company was from Slovenia.
You missed one obscure engine type, the turbine. Leno has one, the Y2K.
Another type, that has been used to break records, the chamber-less rocket. "Powered" isn't quite right, though. "Motivated" fits better, since it's not rotating the wheel but just being pushed. Like a warhead with a seat.
Best motorcycle show anywhere... and quickly moving toward best show period... it shows you guys love what you are doing and care enough to do it right.
Motorcycles. Education. Humor. The trifecta of perfection right here.
Right? And brilliant production to boot!
These engines are the answers to all those who asked "what if we..." It's always a surprise to see how soon almost all the successful engine configurations were developed. Everything since then has been refinement , something to bear in mind when a company say they've developed a ground breaking new design .
Although the tip seals of the Wankel engine were the most troublesome to lubricate, both sides of the rotor also needed seals, so a fair amount of combustion gas leaked into the crankcase as well. An interesting cousin to the Wankel is the more recent "Liquid Piston" design which in the shapes of the rotor and stator are reversed, ie, a two-lobed, rounded rotor and tri-lobed stator/combustion-chamber(s).
I wish they named that engine something else.... "liquid piston" just sounds like some scammy startup to take investor money.
It is a really cool design and a simplified take on the Wankel.
@@volvo09 I agree on the dumb name. I thought of a worse one, though. Since it is a kinda backwards Wankel, "Leknaw" comes to mind.🤓
@@volvo09 On a more serious note, though, Liquid Piston seems to be expending significant effort to get it to run on JP4 and diesel fuel for the military. The higher pressures make the seals even more critical.
The compactness of the engine would make it good for motorcycles and as a small "range-extender" engine for electric vehicles. I think that Mazda is looking at doing a similar thing with its Wankel.
@@volvo09their approach makes getting a good seal even harder.
@@anonym3017 What makes you say that? My understanding was that it solves the seal problem since the motion of the rotor when it approaches TDC is very close to reciprocal.
I remember reading Popular Science as a young teen, when Honda introduced the oval piston. I still have a hard time comprehending how it could work, but it did!
well it did but not really
@@nicozimmermann8672 HAHA Yeah, it worked. Just not for long.
Excellent presentation... nothing seems too dark or ancient to appreciate the ingenuity of modern engineering. Thanks Fortnine
Humour, physics, history, and general information all wrapped in an entertaining delivery.....FortNine produces what is quite possibly the perfect 12 minutes of video available.....anywhere.
You said radial and then gave explanation of and showed a rotary. Radials don't spin around the crank, rotaries do. They do look similar from the outside though. Most old aircraft engines are radial.
I have seen pictures online of 2 different bikes that 2 individuals have custom built with radial engines though, cool but custom one-offs rather than serial production.
I am grateful to have worked on a few of the bikes featured in this video. Not literally the bike's Ryan featured but close to exact models. I rode an RG500 when I was 18! What a trip that was and the owner still has it today.
I’m in my 60s, an aircraft engineer and been into bikes since I was 15, but your videos are just brilliant. Obviously I knew some of the engine design theory, but I also learnt an awful lot, particularly about power stroke/balancing/cylinder configuration stuff.
Pity you didn’t feature the great British icon Barry Sheene when talking about the RG500.
That Honda NR got me. "The result of a decade's perfection, high technology for the new age." That goes way hard.
I’ve never owned or even driven a motorcycle, yet I’ve watched almost every F9 video. This channel is amazing.
What? No motorcycle? You got a wooden leg or something? I got my first one two years ago at 69. Unless you are 100 you should try it, it's like a washing machine for your brain.
@@Earthneedsado-over177Great analogy!
I had the obscure Honda NS400R in 1986. A Two-stroke Triple - It was a light and peaky, almost fast sportbike! Coming off an RD350LC, I was in heaven. I wish I had that bike today. I replaced it with a Suzuki RG500 Gamma two stroke 4, a truly fast and scary bike - I loved 2 strokes!.
I had a gsxr400. Lusted after the ns400r
How about the 1927 Scotts Super Squirrel? 600cc liquid-cooled 2 stroke twin. Banned from road racing because nothing else even came close. Saw it at Dreamcycles, a moto museum definitely worthy of a visit.
@fortnine You MUST visit the Solvang Vintage Motorcycle Museum in Solvang California. Ive seen several of the items you shared today in person, and spoke with some very nice people that work there!!! Its a beautiful village with lots to do, and the museum is quiet and pleasant every time i fly across the country to go there :)
Dreamcycle Motorcycle Museum in Sorrento! An amazing destination for two-wheelers. A massive collection of bikes from across the ages. The owners are always there and love to give you a history lesson on some of their oldest bikes, some of which you may not find anywhere else in the world
I was surprised that you selected a Japanese race bike from the 70's as your example of a "square four". In England, Arial produced square four bikes for street use from 1931 to 1959.
I from the UK and its the Arial 997cc ohv 4-cylinder famous Square four engine
I thought he might mention the inline twin two strokes of the same era - Kawasaki and Rotax .
My father once had an Arial Square Four, and my grandfather had a single-cylinder Harley. And all I have are the photos. Drat!
@@johnpope515 Actually, the Ariel Square Four was originally (1930) a 500cc engine, designed by Edward Turner in 1928. In 1932 it was enlarged to 601cc and enlarged again to 996cc in 1936. The 997cc version wasn't made until 1953 and in 1959 Ariel ended production of all their 4-stroke machines. Excessive heat build-up in the Squafa's rear cylinders was a perenial problem, even in the UK's cool climate. In warmer climates, like here in Australia, that tendency was magnified.
@@chrisweeks6973 To me it sounds like yet another design that would benefit greatly from water cooling
Simply brilliant. Can count the FortNine crew to always be creative, fun, entertaining, and informative.
Idk, I keep seeing that langen v twin and thinking how cool it is, and that liquidpiston thing, if it ever comes to anything
@JackWilke Welcome to You Tube, the platform of free speech. I'm on my 13th account in just 3 years and one month. Excellent choice in channel selection BTW.
Please don't stop making these videos, Ryan. Educational, easy to understand, and hilarious
The Czechoslovakian company Manet also made a "Twingle", it was called the Manet M-90. It was produced between 1947 to 1951 and it had a 90cc engine
the twingle is very similar in operation to an opposed piston engine. I believe the simpson opposed piston engine was one of the first used in a motorcycle. Many of the early engines such as the brayton cycle used two cylinders but it was found that the otto cycle were more efficent.
Were the Czech Jawas also Twingles? Here in India, the Jawa/Yezdi motorcycles from this era also had an extremely similar looking and sounding engine
@@prit04 no, the 250/350 2 cylinder jawas were just a classic twin
idk if y'all read comments but id love to see a video on swedish moto skis this winter. Maybe the history of them and then some modern diy ones that you make yourself. Cheers!
I'm guessing that's similar to the model T kits used in New Hampshire usually with a tag axle behind the drive axle with something like skid steer tracks around the rear sets of wheels?
@@davidpawson7393 the model t kits ive seen replace the frount wheels but the swedish moto skis act more like outriggers you can put your feet on
The NR750 is a masterpiece. I fall in love with it every couple months I see it.
Blooper at the end was hysterical 😅, can you just make a blooper reel of all the episodes as a holiday special 🎉
Something else of interest that Honda learned from the Oval piston bike, and that's how to seal cylinders better. The amount of engineering they went through to make that wonderful abomination work meant that when they gave up and started building normal engines again the rings sealed that much better than they did before. Not a complete waste of time by any means. Their 4 strokes were second to none for a while.
Waking up to a new Fortnine video is like getting excited for Saturday morning cartoons again 😌
One thing I would LOVE to see Ryan F9 do a video on is about the East German marque MZ. An amazing history and racing heritage from behind the then Iron Curtain.
Only reason Suzuki became competitive is cos an MZ rider and engineer defected across the border and took the expansion chamber tech designs with them.
And if Ryan is ever in the UK again, theres an offer for him to ride a 1990s MZ 125 on the table ^.^
You can see this bike and the first car in the Mercedes museum in Stuttgart. I lived there and visited it many times. It’s totally worth it :)
Hey Ryan, I'm gonna need all your b-roll on that RG500. That thing is beautiful.
I adore these videos and this channel. Thank you for teaching me about motorcycling, art, engineering, and good writing.
Anyone else get the gun reference at 12:00 ? LOL!
Also, did Ryan say "centrifugal" instead of "centripetal"? 5:27 I thought he said it was the "so-called centrifugal force" in earlier videos...
This is a spectacular channel. A whole bunch of information I would never have known expertly (and humorously) presented. Freakin' awesome!
I am a mechanical engineer with a specialization in internal combustion engines but I didn’t know such historical details. It’s great to see the evolution in engineering
He’s right: you don’t disappoint. I got into channel a few years ago, before the long-buried desire for a motorcycle reared its lovely head again. It still says something that I was enjoying your videos back when I didn’t give a shit about motorcycles.
TBH, at this point I click the like button, and then watch the video. It's always the highlight of my day when you guys upload a new one!
my favourite of all your videos, an absolute tour de force.
I wish you would do deeper dives on these some day.
I had a 1966 Sears 106 to ride on trails when I was 13. God I wish I hadn't destroyed it.
Amazing vid, as usual. You’re the best Ryan! Thank you for all your hard work!
My favorite channel. Never a dull video. I don't care as much about the bicycle content, but respect its relationship to motorcycles, so I appreciate all of the content. Motorcycle heritage is so interesting and important. That Honda exec., wow, hilarious stuff.
That Honda "exec" was Mr. Honda himself. Founder of the largest motorcycle manufacturer on planet Earth.
The writing is world class! Jam packed with both wit and insight. I doff my hat to you guys.
Too bad it's just a comedy
Thank you so much for this entertaining, educational engineering Master Class of a video! I adore the NR, never knew it pioneered the slipper clutch, though!
I got to ride on and RIDE the mid-Seventies Suzuki 850cc Triple, a liquid cooled two-stroke, three cylinder sport touring bike, nicknamed the "Water Buffalo." Oil and gas had separate tanks, but the oil was auto-injected into the cylinders; at idle the smoke was noticeable. It was big and heavy but fast and smooth, with an unusual exhaust note and no vibration. Riding double it really settled down into a smoooooth and fast roadster! Only when "engine compression braking" with the gears and no throttle did the idle get uneven and shake the whole bike. It was big fun for a small price, but did not sell well and disappeared quickly. "Rice Burners" had not caught on quite yet...........................elsullo
Great writing as always, and the tighter pacing with the b-roll is much appreciated from the last one!
The entire F9 team is top notch. Its impossible to get bored watching these videos. I think this is the only RUclips channel that I will gladly watch every video even when it isn't about a topic or subject matter I'm not interested in. Keep it up guys!!!!
Excellent crash course on engines. Awesome as always!
Heh, crash course. I see what you did there.

quality>quantity
In 1974 I was shopping for a new motorcycle with the limited budget of a US Army Private. What I really wanted was a Norton 850 John Player Special. That was impossible on my budget. My second choice was the Suzuki rotary RE5. I really wanted it. But $2600 in 1974 was impossible too. Kawasaki Z900? Kawasaki 750 triple two stroke? Honda CB750 Four? Nope. I bought a Honda CB550 Four and it was actually a great bike.
Absolutely brilliant as always Thanks
Well done Ryan and team I had not heard of a oval piston engine !
Ditto. I've wondered about oval pistons once or twice before, but now all my questions have been answered by RyanF9 & crew. :)
Fun fact. Modern day 2 strokes DO pass European EU5 homologation. Basically all 2 stroke enduro bikes for that matter! How they do it could probably be a video in itself... My TPI 300 documentation says it makes about 15hp though 👀
Fascinating..... great work Ryan!
Another brilliant topic covered expertly. Thank you sir!
Wow - what an excellently educational video!
Top quality video, as ever. Coincidentally, today I watched a video about a recent bike auction in Birmingham UK. They reported that a Brough Superior made £240,000 at the auction!
It will be hidden away and never ridden, a crying shame, T.E.Lawrence knew how to ride one far and fast
Love your videos Sir! Keep up the great work.
Amazing, entertaining and fabulously delivered.
Being on the hot seat takes on a new meaning.
I would have never known about a radial-powered motorcycle without this video because I would never have thought anyone would even think to try it since...well, it's a phenomenally dumb idea. But that's why I love this channel.
The engine shown is a rotary where the cylinders and crankcase rotate. There have been some custom bikes made with a radial engine where the cylinders and crankcase are fixed. There are 2 versions, one with the radial across the front with the cylinders sticking out the sides this gives a wide bike. The other has the engine in line withe the cylinders forwards and back, this gives a narrower bike. The radials used tend to be Rotax radials designed for aircraft.
Death, Taxes, two strokes, and Fortnine making the best motorcycle content.
Those are the only truly reliable things in this world.
Awesome video, Ryan, such great info, always learning something here.
Love how they reused ryan's "nooouu"
I loved your joke about the American voter dilemma lol. You guys are amazing. I never even heard of the square four before this. F9 is so freaking good!
That joke was awesome!

Great vid team, keep up the exemplary work
Really appreciate these videos, didn’t know some of these engines existed!
I had complete faith that you wouldn't miss the NR750! Have you seen the Liquid Piston engine? I think it has a bright future.
I have seen the Liquid Piston! What do you like about it? Despite all their marketing materials to the contrary, it just looks like an inside-out Wankel to me. ~RF9
LiquidPiston is a scam
Your writing and delivery are still the best in the business. Great video!
Love the videos Ryan, saw the Wetbike behind the “Twingle” bike!
That’s my Winter project this year! I’ve always wanted one and a friend found one for me a few years ago and THIS winter I’m going to restore it!
Ryan is incredibly knowledgeable. Glorious content.
My dad fought the Japanese in WW2 and refused to buy a motorcycle made out of “recycled beer cans” but buying something made by the Nazis was ok. He bought my brother a used Sears Allstate 60cc enduro (by Puch). It was FAN COOLED! It made a high pitched whizzing sound and broke rear spokes routinely from its “awesome” power. He loved Sears Allstate crap so much he bought a used Allstate 250cc Twingle badass machine. I had fun riding it around town a few times at age 14 and even perfected my Indian Joe stunt of standing on the seat. Good times.
this guy is one of the reasons i still watch youtube
I'm glad we have this chanel
Thanks yet AGAIN Ryan!
You never fail to educate and entertain.
Top notch!
"If we don't want the bizarre then we're left with the ancient- a dilemma American voters are familiar with" - Pure Genius!
one of the things i would appreciate you and your team do is a video on some Indian motorcycles considering how utility based the Indian market is.
you can obviously do videos on karizma xmr, some tvs or bajaj bikes plus you can attract some Indian audience
I assume it's a bit complicated to get those in Canada.
Always love your stuff!
This might be the first time ever I'm tempted to "click the link below". Low pressure tactics, great video looks like genuinely good optics. You got me!
My favorite engine is the V-4 1st generation V-Max. If you've ever driven one you understand the attachment 😊
Sound good, too.
I love my xvz1200 venture. Same motor, slightly detuned. It’s a fantastic bike.
At 06:13 you show a rotary engine with 8 cylinders. As far as I am aware all rotary engines use an odd number of cylinders and when firing skip one cylinder each time.
If I recall correctly, most (all?) rotary radial engines are actually two stroke, so they would be able to fire every TDC. The radials that everyone thinks about are not rotary and have a fixed case, and four stroke and so they have to be odd numbers in each row so that skipping every other cylinder when firing means that in two full rotations, each cylinder still gets fired. So each *row* on a four stroke radial would have to be an odd cylinder count, but you will see even numbered counts when dealing with multiple row engines. (ie an R-3350 radial is an 18 cylinder with a pair of 9 cylinder rows).
Yeah he made a mistake in the video, that's a rotary which spins around the crank not a radial which stays stationary and turns the crank like a regular engine. As previously stated most radials are 4 stroke and have an odd number of cylinders per row/bank, and most rotaries were 2 stroke with an even number of cylinders.
@@OskarGibson It's still a radial engine, and given that the Wankel has functionally entirely taken the name rotary for itself, referring to them as rotary radials isn't a bad idea, and it's what RF9 does.
Great video as always, Ryan!
Exceptional explanation of the various motor types. In typical F9 fashion. Bravo!
The twingle was done by the German Triumph as well.
fortnine has been stealing my videos for years and nobody cares
It is good to see a real Fortnite video again! I know no one has yet crammed one into a motorcycle, however I was really hoping that he would get into the swash plate /revolver cam engines. In my armchair engineering mindset they seem like the ultimate type of liquid cooled motorcycle engine. They only ever appeared in light aircraft, however from what I have seen the revolver cam engine was a perfect evolution of the internal combustion engine. Look em' up!
Always interesting high quality content. Thank you.
Thank you, I really enjoyed it. And, thank you for the bucket list ride suggestion.
I wish RUclips had a two-thumbs-up button. One doesn’t feel sufficient for these videos.
Could you not do an H-four but have each set of pistons reciprocating opposite of each other? So while top set is going left, bottom goes right. You'd end up with a little rotational torque instead of just shoving the mass side-to-side, but it seems like it'd be more manageable.
You could but then your motor will be trying to shake back and forth like a multi tool.
Perhaps, but why? It'd be far better to just make a Boxer instead.
Also, H is the cylinder layout, not the crank geometry. Boxer engines are still H engines. Although technically incorrect, H engines are commonly called flat engines.
@@rightwingsafetysquad9872 Flat engines can be either Boxer or 180deg V depending on the crankshaft.
@@gustavmeyrink_2.0 Technically, yes. But except for twins, boxer engines never use a flat firing order. Ferrara used a flat order in their BB and Testarosa series 12-cylinder engines, but no longer does.
A proper flat engine is 2 pistons in a common cylinder, each piston on a different crankshaft. Think of a Porsche H6, but inverted, crankshafts on the outside. AFAIK, no such engine is in use today so the term ‘flat’ has been bastardized. Now it also means an engine with 2 cylinder banks using a firing interval as if it were 2 separate inline engines.
@@rightwingsafetysquad9872 The Ferrari flat12s are all 180deg Vs.
The engines Porsche used in the 917 are also 180deg Vs because the boxer layout does not provide any benefits any more in a 12 pot but just makes the crankshaft unnecessarily complex and heavy.
What you describe is an opposed piston engine like the Commer TS3 or Napier Deltic. Every opposed piston engine I know of is a 2stroke diesel. Then again the only ones I know are those two and the Junkers Jumo 205/223.
BRM built a H16 which was basically two 1.5L 180deg V8s on top of each other.
fantastic combination of technical education, entertainment, subtle innuendos and class, well done sir, you deserve a TV show
Love your work
Wankle. Never not funny.
