Honda well understood the physics of Horse power. If you study the various equations on how much HP an engine of a given size can make, you soon see that the faster you can spin that engine, the more HP it will make. And you can spin an engine with tiny cylinders very very fast...18,000 rpm fast.That would have been a blast. Especially now that FI could eliminate a six-carb fuel rack.
But that tiny six...the smaller the cylinder, the less vibration, even given a single or twin engine. My Yamaha XT250, while a thumper, scarcely thumps. I compare it to my long-gone SR500...which most decidedly did thump.
My short-stroke Nighthawk 700 four is a LOT smoother than my departed CB1100. Smoother and quicker to respond on the throttle - odd since the 1100 had modern fuel injection.
So. A 250 six, with pistons like shotglasses. Man, that would seem likely to JUST...PURR.
Sorry to hear that story @suvcw04 - I think that most of we older riders have a tale of that type somewhere in our memory.The son of a friend of mine had a 350 Four and a 6 cylinder CBX 1000. At the same time!! He loved multi cylinder bikes and had the money to buy them.
Unfortunately, he and the CBX went straight when he should have turned. On hiway 63, north of Waterloo Iowa, before it was rebuilt as a four lane, there was a section called "the county line curves". The mainly north-south road had a 1 mile east-west section with two 90 degree curves. He was going south and kept going that way when the road made a 90 degree to the right. There was a wooded marshy area at the curve. It was 4 or 5 days before he was found. Too much horsepower, too much speed, that lovely motor at full chat.
The last I knew, MANY years ago, his father still had the 350 Four. It had not been started since his son died on the CBX.
I tried once to buy it, but when I saw his eyes, I didn't press the issue and never asked again. I would guess that he HATED that little bike, but it was a link that he could not give up.
Everything has a good and a bad. Just remembering and typing this post . . . well, I'm getting too old for this s***.
Interesting link...thanks!Before the FIM changed the engine rules for GP bikes, the Japanese companies went crazy with multi-cylinder bikes in every class. Suzuki had a 3-cyl 50 (16 cc per hole!) and Honda had a 125/w 5 cyl (25 cc per hole). My Ryobi string trimmer beats both of those with a HUGE 41 cc single cylinder!
This Suzuki racing motorcycle has 14 gears
By Richard Fowler of Motorsport Retro. This amazing piece of machinery was the last of the purebred 50cc Suzuki racebikes built in 1967. And it’s a technological as well as aesthetic masterpiece: the engine was tuned to an extraordinary 350hp per liter. The RK67 motor was a two-stroke...www.bikeexif.com
European companies had no way to keep up with such technology and I'm sure that played a major role in the FIM enforcing cylinder and transmission gear limitations starting in the late-60s. What really amazed me is that within 3-years, tiny Euro race builders such as Jamathi, Derbi, Kreidler, etc., had elipsed all the lap records held by the Japanese bikes in the 50 cc class. These race bikes came from moped & scooter companies that funded a tiny race shop with only a few people, unlike the army of engineers at a Japanese company with nearly unlimited facilities available.
Now that is a truly classic oxymoron... George Carlin would be proud of you!4-wheel motorcycle
I do believe that Jay Leno has one. He also has a jet bike too. I live about 2 miles from his warehouse near the Burbank Airport. I do see him from time to time driving one one of his cars. Motorcycles it’s a little hard to tell as he’s wearing a helmet. However, I his signature denim shirts give him away on a warm day.Does anyone remember Chrysler's 4-wheel motorcycle built around the Viper engine? It was called "Tomahawk."
Here's a Youtube video: 2017 Dodge Tomahawk Reviews - YouTube
I notice that the front suspension seems pretty soft and that the video does not show the "bike" turning except a slight adjustment in direction a couple of times.
The guy is a genius. The fact he can just cut and paste engines together is insane. Apparently some of his bikes are on display at the Barber Motorsports Museum, including one of the Kawasaki V12s. I may try to swing through on the next cross country ride, will probably be the only reason I would ever have to step foot in Alabama.....and if you'd like to build one of your very own, here's how (courtesy of the remarkable Alan Millyard and his hacksaw...):
I enjoy the YouTube clips of Leno's Garage I've watched and never felt that Jay was trying to pass himself off as a technical expert, nor an expert rider.
He's an ex-talk show host who now uses all that money to keep & restore cars and motorcycles.
