Well.... if you ride on a bumpy forest canyon road, Isle of Man TT style, and still get a bit of molten tire compound on the side of the front and rear tire when it's only 0 to 6 degrees Centigrade outside... you are at the point where you can actually feel the frame working and complaining. Front suspension is GSXR 750 '92, rear suspension is RGV 250 '92 and GSXR 750 '92. The bike stands on Pilot Power 2CT. Only thing I haven't got, yet, is a steering damper, I kind of enjoy the handlebars slapping around.
