Hey are there any VTR 250 riders who experience the "my ass is so numb I have to get off and walk around for a bit" feeling"? This is just before it turns into pain.... I love my new little bike, but after an hour or so, its time to get off for a stretch. Are these little rockets not supposed to do distances or what? I'm considering either a sheepskin or an upholsterer to soften it up a bit.
