for those who are unaware as I was, crampbuster comes in at least three models. a wide shorter model; a longer narrower model with a smaller diameter handlebar curve; the same model with a larger diameter curve. these are held in place with 'spring' tension built into the plastic. a fourth model uses a velcro strap, I don't know who makes it. I have used both 1 and 2 and I like the second one best for my 650.
