Stage6 Primary Gear 13*43 Kit (Aprilia, JOG, Zuma 50)
Description: Stage6 Primary Gear 13*43 Kit for Aprilia, JOG, Zuma 50, and many other 50cc base engines. Taller gears in the transmission reduce the overall reduction factor of the gearbox. This modification will raise the top speed if the engine is powerful enough to pull the taller gears. Only use with tuning kits! Original cylinders are normally not powerful enough to pull this sort of gearing. Contrary to common gear units, the ones from Stage6 come ready-pressed and are available at an unbeatable price. Replace the old gear unit with the new one - possibly!*
†Attention! The intermediate gear needs to be replaced by the original on BWS/Zuma 1988-2011. The small gear needs to be removed and replaced for the OEM one.
