The shock length is 15" center top bolt to center lower bolt measured on the bike. The setup works very well for me. My kick stand is stock - no issues - and the belt just touches the master cylinder bracket with no load on the bike (the belt is very slack too). As soon as you sit on the bike the belt tensions and everything is fine. The shocks were fitted by the original dealer and the bike's now done 6500 miles. Still the first belt, of course, with no signs of damage or deterioration.
