2x Balance Shaft Gears For Aprilia RS 125 Rotax Engine – Transmission Gears (Pair)

If you're rebuilding or repairing an Aprilia RS 125 with the Rotax engine, this pair of balance shaft gears might be exactly what you need.

They're the gears that go into the transmission area to drive the balance shaft, helping keep that single-cylinder thumper smooth.

These are new, unbranded replacement parts made in China.

They're sold as a set of two.

No manufacturer part number, just the gears themselves.

If your old ones are worn, chipped, or noisy, swapping in a fresh set is a smart move during a rebuild.

Double-check your model and fitment before ordering, but if these match, they'll get your Aprilia back on the road running smoother.
