I just installed a Hyperpro Progressive Shock on my Versys. Had it painted Lime Green of course. (their version of lime green anyways).
I weigh in at 280, 6'1. If I set the shock with the new spring to the stiffest setting, the bike does not even budge when I sit on it. I have dialed it down a bit, but I like a stiffer ride than most.
It sure is easy to ride wheelies now. It used to be only wheelies in first and then only under power. Now I can get the nose up in first to the balancing point and ride it as long as I can stay balanced. I am thinking it is due to the stiffer back end. Not sure, but took it for a test drive after installing the shock and all of sudden I was able to do that. I think it is the no sag when I gas it. Before with my weight and the std spring I would get a lot of sag on the bike.
I gotta say, I love the new spring though. Took them quite awhile to find someone who could powder coat it the green color. They called back a couple times asking about another color... But I stuck it out and they found someone. I even told them the colorite codes, but whomever did the paint, did not use them.
Not sure why the delay with the paint, it took 2 months, but they were honest about it and kept me in the loop. I thought that was cool and would buy from them again.
