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.......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 ***** 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?

DR.squid

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!!!!!
