1250 vs Hayabusa engine

I'm wondering what the differences are between the 1250 and Hayabusa engine are. And if they are not the same why wasn't the Busa engine used for the Bandit. Thanks, BanditBen

different engines...all Bandits, water and air-cooled, have the cam chain in the center of the engine.  The Hayabusa has the cam chain on the side.  I can only assume it was less expensive to adapt the machining of the original GSX-R/Bandit engine instead of making a Hayabusa variant.  One reason also might have been to differentiate the B-King from the Bandit, since the B-King did have a Hayabusa-based engine.

Completely different engines buddy.  The Bandit is all about torque with a high end that happens to have decent power.  The Busa is a high speed machine so torque isn't nearly as necessary as high end horsepower.
Also on the Hayabusa, the engine is a stressed member of the frame.
On the Bandit, it's an engine-in-cradle design.

What we really need is two engines strapped to the same frame! For normal everyday power we have have the bandit 1250 mill churning its massive low end torque. Then when we really want to go jihad we kick in the the Huyabusa engine for maximum take off velocity. Two engines on the same bike? That'll teach those global warming alarmists!
