dunno mate, but they love draggin' those elbows !
I still recall clearly, the commentators at the time calling the 250GP, were just amazed and basically could not believe the lean angles that JPR was getting on that 250, and at one of the GP's, they did some close-up footage of his elbow-scrapers after a race, and sure enough, scrapes all over them......it was just unheard of back then...........
My elbow scrapers should be here from ebay next week mate !!!! Expect to break them in on the CDT next year !!
