I weigh about 165 and actually am about to shim the shock up a bit to bring the ass end higher but i do love how the gixxer shock rides!! but like zx racer said......if you're heavier then the busa shock may work best for you.i'm just not 100% sure on the mount height for the busa shock? but i have tried shocks from a ZX6,03' gixxer 1K, and 08 gixxer 1K, i just like the 08 gixxer shock (i have a spare one too :mrgreen because they have been re-valved and ride like a dream. or at least i love the hell out of it!:badteeth:Thanks man...I am just trying to stretch and lower the bike. I have a strut on there now and its killing my back at the moment. I like how low the bike is sitting with the strut but I just cant stand the ride. Do you think the gixxer shock will fix that problem?
