Wow. What an upgrade over stock. I put a set of these shocks on yesterday and laid down 150 miles after the upgrade and my bike handles like it's on rails now. If I had any idea how dramatic the improvement was in handling and ride quality I would have bit the bullet years ago and spent the money on these shocks then.
There is a rotten ass pot hole north of Tweed on highway 37 that gets me every time I return from Cam's and sure as shit it got me again yesterday after the shock upgrade. Normally my bike would bottom out and I would feel the shock in my lower back, but with the Progressive shocks all I felt was a little bump. Cool stuff.
I have also had problems with my bike shooting in one direction, or the other when I stabbed the throttle that I was convinced was the crappy stock air shocks collapsing under heavy load. Keep in mind my bike has double the amount of HP that a stock TC88 does, so it's a lot more violent when you get on the hammer than a normal bike. With the Progressive shocks my bike tracks as straight as an arrow now even at excessive speeds. Just ask the cop I blew by at X mph in a 50 zone yesterday. He flashed his lights, but didn't even bother to pursue.
