right i will be 172ing the drag shortly. the bike has only 6900kms from new. will i need to change the crank now or just basically ride it until i kill it :w00t: im not going for a silly tune but i may not opt for a gear up. it depends what i actually use the bike for cheers
6,900km i would'nt bother tbh. get 180 gears if you dont fancy a gear up. still very good bottom end and a few mph top end.
you saw my old runer monty that had polini varo 15g rollers 172 pm 59 polini reeds hebo inlet 28mm/25mm [ changed] malossi cdi race plug 90 clock speed 125 gearing and that was on the standard crank i think that standard cranks snapping are over exagerated
