I have owned my Bike ( Buell xb9r ) for about 2 years now . I have clocked up 12000 km and have not had a problem at all . The belt still looks like New . I do not wheel stand the thing much ,but i do push it hard ... I have ridden ( Jap ) bikes for over 23 years on the road and I will never have anything else then a Buell now . They get in your blood ;-)
