no, the 750 shocks are actually shorter than the 550's. it's not so much the spring rate that makes it handle like it does, it's the damping characteristics. needs more compression and rebound damping, but they're not adjustable. if you really want it to handle nice, you're gonna have to go buy a better set of shocks than any factory honda shocks. progressive and works make good quality shocks for that bike, just make sure they're the right length.
