Guest JKirk Posted March 19, 2007 Share Posted March 19, 2007 I've read about directly replacing the VTEC forks with a set off a F4i, but does anyone know if the RR forks are similiar enough to be an easy swap? Link to comment Share on other sites More sharing options...
SEBSPEED Posted March 20, 2007 Share Posted March 20, 2007 03-04 maybe, I don't recall now if they're the same diameter or not, they're sure to be a bit shorter though. The 05+ USD forks will definately be too short. Just do the F4i swap, they're going to be so much better than stock anyway! Link to comment Share on other sites More sharing options...
WERA910 Posted March 20, 2007 Share Posted March 20, 2007 The 03/04 600rr front end has 45mm conventional forks, vs the Vtec's 43mm... Link to comment Share on other sites More sharing options...
Member Contributer FotoMoto Posted March 20, 2007 Member Contributer Share Posted March 20, 2007 As wera910 said, they (03-04) are larger so you'd need the triples plus bearings/races. The later model USD units are usually much shorter. Link to comment Share on other sites More sharing options...
Guest Posted March 20, 2007 Share Posted March 20, 2007 Thanks for the info, had a guy about to give me a set cheap... I'll keep looking for a f4i set. Link to comment Share on other sites More sharing options...
Baileyrock Posted March 20, 2007 Share Posted March 20, 2007 Thanks for the info, had a guy about to give me a set cheap... I'll keep looking for a f4i set. F4/F4i work. The f4i has .660 springs and the F4 has .740 springs, neither of which is stiff enough! Also the F4/F4i forks allow the use of the stock VFR wheel,axle, rotors and spacers. All you really need is the brake master cyl., lines and calipers and front fender. :thumbsup: Link to comment Share on other sites More sharing options...
Guest Posted March 20, 2007 Share Posted March 20, 2007 Thanks, I may just go ahead and buy .95 RaceTech springs for now and then I can move them over if I ever get F4i forks. I think their the same... No luck, called Racetech and the .95's are on bacl order for weeks, guess I'll just go ahead and put the forks back on...
