Well, after a year with the Matte grey finish, I have a "grapefruit size" polished spot, on each side of my tank, where my knees rub on the tank, caused by rubbing during hard cornering. Knee on the tank side, and pressure on the foot rest during the corner, has worn the spots on each side. I don't mind, tho. Kinda like war badges on the 6. I guess I could get some of those tank pads, that I've read about in other threads, If the spots ever start to bother me. Anyone else have these on their 6?
