I lowered my seat already, and would also to lower the suspension. I have settled on Progressive 412's, but not sure if to go with the 11.5" or 12" length. I am 5'6" 175lbs. Ride solo 99% of the time. Mostly comfort change, some cosmetic. Any input is helpful.
Ride great...... They've been on for about 6 years...no problems. I only ride solo (wife rides her own). If I were to ride 2 up, I'd have to crank down on the springs a bit, but I like them alot.
Find some boots with thick soles and heels. The less you lower the suspension the better the ride and you give away less precious cornering clearence too.
