PRIMARY KIT BGM PRO EXTRA LONG Motors with a lot of torque and an early power peak choose the straight-toothed clutches that also require a straight-toothed primary gear (also available as a set with clutch). This enables very long reductions to be achieved. Also perfectly suited if the overall gear ratio is too short in very sporty engines with a modified auxiliary shaft and shorter gear steps (e.g. MHR). Another option if the actual transmission is very short (PX80) or the gear ratio is too low due to a small wheel diameter (PX200 motor with 8 inch tires in Oldie).

GEARS The extra long primary reductions based on the 62/63 tooth primary gear are only available with straight teeth and therefore cannot be combined with conventional (helical-toothed) drives. The high torque of the motors, which require such a long reduction, is introduced directly into the gearbox via straight teeth without exerting lateral forces on the bearing of the auxiliary shaft. Thanks to the precise production, the straight-toothed drives are just as quiet as the helical-toothed ones. PRIME ...
