anyone done it? any modifications to the frame? any advice would be appreciated

 

next winter after i am done beating the he11 out of my 2002 cbr 600 f4i its going in!!!!!!!!!!!!!!!

 

There is a race shop online that will do it for you and says 150mph + I can't remember the url it's been a while. Sometimes they auction these quads on e-bay they have builds like this for banshees and quadzillas as well.

 

wouldnt the new 600rr or yamaha r6 engine be better if u have the money

 

i can get ahold of a crashed cbr for under 600 plus, its always a lot better to stick with the same manufacterer
