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.
Jaysus, I haven’t heard the Aerial Square four mentioned in 50 years. I nearly bought one almost 5 decades ago. I’m glad I didn’t, at the time, (went for a Suzuki water cooled, 2-stroke in-line triple), but nowadays, I wish I’d ridden it.
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!
@@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. ;)
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.

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.
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.
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.
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 .
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.
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 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.
@@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!
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 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!.
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
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.
@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 :)
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!!!!
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.
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?
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
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.

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.
@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.
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
Ah, the GT750 - I remember it well. A hand-me-down from my brother, it had an expansion chamber on it the size of a dustbin. You could hear it from 7 kilometers away :)
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.
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!
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!
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.
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.
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.
@@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.
The writing on this channel is phenomenal. TV shows only wish they had writers this clever. The host is great as well, and he most likely writes a lot of this stuff.
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 ^.^
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!
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 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!
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.
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 👀
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 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
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.

First I'd heard of the Twingle and I already love it.
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!
The video we deserved, but not the video we needed(technically, asked for). You're like Moto-Batman from the Dark Knight trilogy.
Wow - what an excellently educational video!
This was the video I never new I needed to watch about engine configuration, until I watched it.
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. :)
Amazing vid, as usual. You’re the best Ryan! Thank you for all your hard work!
I had a 1966 Sears 106 to ride on trails when I was 13. God I wish I hadn't destroyed it.
You guys are honestly the best channel on RUclips
Really appreciate these videos, didn’t know some of these engines existed!
Superb, instructive and dead entertaining, all at the same time - not easy to achieve, but Ryan manages it every time!
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!
Thank God our dinosaurs will only bedevil us for a few more years, while Canada's Son of Castro will be around for decades.

@@patmcbride9853 Worry not, there will always be more 60 year old rich white men ready to step in
@@tappajaav 60 seems downright young right now.
Your writing and delivery are still the best in the business. Great video!
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.
Yes the mighty Twingle! Got a Puch Twingle sitting at home, great bike! Nearly indestructible
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 👀
What a absolutely amazing video. I never knew about half of those engine types.
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.
and again a must watch video for all!
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.
Another killer video. This channel is the best entertainment on all screens.
Being on the hot seat takes on a new meaning.
I have to admit: "Exercise in eccentricity" was a good one !
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
Exercise in eccentricity? Wonderful, a genius stroke of writing
Ryan is incredibly knowledgeable. Glorious content.
Amazing video fortnine you guys dont fail to impress
Love how they reused ryan's "nooouu"
Back to the roots in this nostalgic episode. Onwards and upwards - to the future.
11:04 If we don't what the bizarre we are left with the ancient - a dilemma American voters are familiar with.
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.
