The Yosh Hayabusa

[OB_BarryW.]

It's nowhere near as bad as a 500cc GP machine in terms of power-to-weight and wheelbase. Someone on the board will know exact values, but I think GP bikes are closer to 200hp, probably over a hundred pounds lighter than the X-1 and a couple of inches shorter...talk about balls of steel!

I read the article in MC finally and noticed that they put a SHORTER swing arm on the 180HP Hayabusa they created. 25mm shorter than stock to be exact. They beefed up the engine to produce over 180 HP!
I am curious why they didn't fit a LONGER swing arm like most of the Hayabusa owners I have seen who are producing that kind of HP?

The shorter swingarm equates to better handling. The long swingarm is drag racing or straight line stability.

I knew that but how does one keep a bike with 180HP going to the rear wheel under control with a shorter swing arm? Won't it be very light in the front?

Very difficult apparently. A Yosh rider was killed while testing the X-1 for Suzuka.
