The Pinion Z=14 is a genuine spare part manufactured by Piaggio so you have peace of mind the Pinion Z=14 part being sold by Motorcycle Spare Parts is both original and new.
For final drive ratio and chain alignment on the RS 250, AP8600325 is the OE 14-tooth pinion (front sprocket) with the correct bore/offset for the gearbox output shaft. Tooth profile and spline fit are critical here because small deviations show up as chain noise, accelerated wear, or poor sprocket retention fit under load.
It’s listed for RS 250 across 1998–2003, so it’s appropriate when returning a bike to stock gearing or replacing a hooked sprocket. Pairing it with a correctly sized chain and rear sprocket is the normal approach to keep pitch wear consistent across the set.
