one "trick" to free-up the drive train before on the XXX-S and XXX-4 was to cut out every other tooth of the BELT, and this really did reduce the friction, thereby freeing-up the drive train... im guessing this is just a variation of that, to make the BD's drive train even more lighter for spec racing.
