I had a derestricted one. Could never get it to top out, just kept accelerating. Brill. bike. Only went to the bird because the pillion seat was comfier for my beloved. (We had to help her off the seat as her legs would seize up on a long journey). only trouble l found, was the fuel consumption was awful because of the small tank, get to about 80miles and you start looking out for fuel stations, and it ran extremely hot especially in the summer, you didnt want to get caught in a tailback.. handled really well if you drop the forks 10mm and change the rear tyre to a 190 instead of the 200mm. Would def. get another if l got the chance. @tu*
