Stage6 Gear Up Kit - Chinese 4 Stroke 50cc


Add to Basket

Stage6 primary gear kit. 17/51 (3:1)

Taller gears in the transmission reduce the overall reduction factor of the gearbox.

So long as the engine is powerful enough to pull the taller gears, this modification will also raise top speed.

The original gears in many Chinese mopeds are quite short which means you can often gain some mph even with original cylinders.

In contrast to other popular gear up kits, the ones from Stage6 come pre-pressed and are available at an extremely competitive price. Simply replace the old gear unit with the new one - and that's it!

Fits all modern GY6 type 50cc Chinese 4-stroke moped engines (e.g. Baotian) with 12" rear wheel.

Not suitable for the Taiwan mopeds e.g. Kymco, CPI, Sym etc.
