r1 frontend on f4i?
 

i have a 2002 f4i with shitty conventional forks on it...i also have a complete frontend from a 2003 yamaha r1 (triple tree, forks, wheel, etc.) i am able to roll stoppies out decently on my 2003 r1 so i wouldnt mind this front end.... i know of people putting 929/954 front ends on f4is and gsxr750 frontends on 900rrs but has anyone done this or does anyone know if it will work before i rip this bike apart for no reason

i have an r1 front end on my 636. all i had to do was bore out the lower tripple tree and i was done. not sure what u need to do to yours. also mine came off an 05. it was an awsome mod..

yo yo....i got a 03-04 r1 front end on my f4izzy.....and its butta!!!!!i have never attempted to try and roll a stoppie UNTILL i put that front end on there:yeah.......bike had white plastics on it at stunt wars...at the tent with the half naked dirty girl!!!!hahaha


used the stock r1 lower tripple...used the stock f4i bearings and races and a 954 upper tripple tree.....when i win the lotto im gonna hit up alls balls and get some new ones....

well 02-03 is one body style r1 the 04+ is different......did u use 03 or 04? bc i have 03 and i wanna put it on.....i also have a lsl 929 upper triple tree with the dirt bike bar mounts on it.....also i looked into the diameters of the bearing and the stock r1 and stock f4i lower bearing are the same but the upper bearings are different and if i shave off a milimeter all around on this upper bearing i am ordering it should fit like a glove......so ur saying the 929 upper clamp should fit on the r1 front end?

Re: r1 frontend on f4i?
 

yea sorry....its a 02-03 r1 forks.....yea the bottom bearing is the same.......and i used the upper bearing cause the inner and outer race......sooo...use either lower bearing and use the f4i bearing and race on the upper...and yea i used a stock 929/954 upper triple tree..butta!!!!!
