+1 on Gixxer front end and on SVRIDER's info, with one qualifier. There is ALOT of different info on different front ends being grafted onto different SV's. I put a RaceTeched '04'05 600/750 (all the same) front end on my '99 track bike. Big, big difference! One of the tracks I go to, Eagles Canyon Raceway in Texas, is hard on the brakes. Cooked stock SV brakes a couple of times there

, which led to the Gixxer decision.
It is important to measure the geometry of the old suspension before you put on the new, so you will KNOW how your geometry changed. In my case the new forks dropped the front end 25 mm, which is HUGE. I usually move in 5mm adjustments. But it's all good,

the bike turns VERY well and is awesome in hard braking on the bumps, just soaks it all up.
