I had one and took it back off and sold it. I was recommended to purchase one when I bought the 1 1/4" lowering kit. But could never get the bike up on the center stand without running up on a 2x6 board and still it was hard. Also, I could not rock the bike to get it off the center stand. If I put a 3/4" plywood under the 2x6 and also under the center stand then remove everything from under the rear wheel and could get the bike off its center stand much easier. But this was all too much every time. I now put the bike's back to original and everything works better but, being only 5' 6 1/2" tall, I am practically on my toes coming to a stop. This was made worse when I added the Progressive Fork Springs. So, I ride with the rear shock set at 1. This weekend, I think I will put the lowering kit back on because of the new Progressives.
