Background: Evidently I'm hard on clutches. I ride aggressively and nail the throttle at almost every stoplight. This, of course means I go through a lot of clutch disks and rear tires... about 1 each per year. I just ordered a set of Barnett carbon fiber disks. Maybe they will last longer. I know... they will certainly last longer if I stop riding so aggressively. It's kind of like handing a prisoner a key, but he decides to just stay in jail.
