See my post on Z400 swingarm geometry in the Suzuki section of the forum. The swingarm angle on the Z is a bit steep, and locks out the suspension due to chain torque under very hard acceleration. The AMP Link was designed to eliminate this. Any users have an opinion about this produce?? As I recall, it has gotten some pretty poor reviews in the past?? Any comments are appreciated!!
