I saw this bike on a google add the other day, pretty cool idea. I always think about getting a mini bike and buying a predator harbor freight engine and making a little hot rod mini bike, lol but this is the extreme hot rod. I always wonder why most of these projects are never finished, this thing is 80% done. The expensive and hard part is done, finish it.

They realise riding results in instant death, self-preservation kicks in and off it goes on ebay.
 
I have pics of a Vespa I saw at Daytona Bike Week probably back in the 1980's, so no digital pics. It was powered by this bikes' big brother, a Honda 500/4 four-cyl. And, it was turbocharged. Painted on the Vespa fairing in wide red letters was its name:

My freind and his brother put a Predator Engine in a Miata.

 
not to split hairs or maybe i missed it in the string but is the motor in Kyles little bike a CB500 motor. as far as i know, which sometimes is not very far, the Honda 350 was a twin. someone up string said it was a 350, just saying :)
 
There was mostly definitely a Honda 350 4-cylinder. It is true that the 350 twin was more popular, but that 350-4 is now highly sought after.
 
Honda 350cc engines came in 1, 2, or 4 cyl's.

Want something smaller, with six cylinders? Honda GP bike the RC-166. Listen to the idle!



If you like that, here is the F1 RA-272 car from 1965, I saw this run at Watkins Glen at the US GP back then. 1.5 litres, a V-12. Max Verstappen is at the wheel, this time.

The Honda commercial with all the vehicles? The RA-272 is in there, front and center. You can recognize the nose and the shape of the opening, the lack of aero panels, and the spindly front suspension.

I stand corrected. I was not aware the Honda made a 350-4. Wasn’t it most notably Mike Hailwood who raced it at the IOM. It really was a beautiful machine.

Honda had 6 cyl engines in both 250 and 350cc sizes in Grand Prix racers. The RC166 had a pressed-together crankshaft of 13 pieces, which revved to 20,000 rpm; some of the oil passages were 1 mm, and the 4 valves/cyl were different sizes. The engineer tasked with leading the design was 24 yerars old, and later would design the Honda CBX 6 cyl 1 litre road bike.

Larger than life-size! Six of these, < 42cc each! Then recall each had four valves above the piston crown!


Hailwood had a British framemaker construct a new bike frame for him, when the factory refused to make changes to allow the factory chassis design to be more-easily ridden. Supposedly that was not well-received by Mr. Honda. The same thing happened in 1960's F1 racing, the Honda engine was finally a winner in 1.5 litre and 3 litre designs, but the car chassis needed input from the U.K. constructors.

Well, we are straying just a bit from Kyle’s monkey bike monster, but since we’re on the topic of six cylinder songs, and having enjoyed one of the beasts over the last few years, I thought it might be interesting for folks to listen to this. In my fairly extensive motorcycling experience over the last 4+ decades, nothing has equaled the thrill of being astride one of these when it’s “on the pipe”:

 
Here's an actual production bike from Big Red, 250cc, 4 cyl 18,000 rpm peak power, 19,000 redline, and a 20,000 rpm ignition cut-off. Did I mention, DOHC, and gear-driven camshafts? All this, in 1991! and it will out-perform the 300cc sportbikes of today. It was first released over 30 years ago!
