I've lowered 2" in the front forks, 17" front rim and 120/70 radial.
Rear is 1.5" lower in the shocks, 17" rear rim and 190/50 radial.
It's low.
Handles fine with just a rider but I can't take the bike over to anything like its true cornering capability without scraping the footpegs or sidestand.
Headers and crossovers will hit some speed humps and curbs if you take then too quickly.
All these clearances are a real problem with a pillion.
I like the bikes profile and don't want to change it so I will raise the footpegs, mod the sidestand, get variable height shocks for the rear and customize the headers to get a higher tighter fit to the bike.
