has anyone ever put a 900rr motor on a f4... if so what does it take to make the swap

 

Im far from an expert but if you have ever looked at a 900rr and compared it to a F4 your fully aware that the frame, swingarm, and all other stress encountering parts are made to handle the extra torque, power, and weight of the 900. I'm just guessing, but trying to shoehorn a 900rr motor into a 600 frame is probably not a good idea. Someone tell me im wrong and ill probably try the switch myself at some point in time.

 

There was an article in Sportrider about 3 years ago about a dude that took a Busa motor and put it in a Gixxer 600. Probably by the end of the deal he'd spent enough money to buy a Busa and a Gixxer 1K -- some peeps just seem to like the challenge.

 

i've seen people put a 92-94 and 95-97 motor in a cbr f2 frame. thaqt just looking around on the net. so it could be possible.?
