The Pinion is a genuine spare part manufactured by Piaggio so you have peace of mind the Pinion part being sold by Motorcycle Spare Parts is both original and new.
High-compression engines like the Aprilia RXV and SXV twins rely on a clean, precise starter engagement, and that’s where the AP9100525 starter pinion comes in. Its tooth profile is cut to match the original pitch for smooth meshing with the flywheel.
When riders start hearing hesitation or grinding during start-up, the pinion is often the first place to look. Swapping in the OEM gear restores crisp engagement and protects the flywheel ring gear, which is especially important on these performance-focused engines.
