I just figure better safe than sorry. The longest my ST2 went was just a hair under 12k miles, but they were five years old, as the bike sat on the showroom for nearly four years (the belts on it will be replaced at the 3-year/12k point in a couple of months). My 748's belts went a little under 6k miles in four years (I just changed those over the weekend). The belts sure *look* like they'd last a long time, but I know don't want to have one break on me.
