Piaggio 8250785 Transmission Pinion Shaft – Free FL/PPTT 50 and Vespa Sprint 50 2T

The Piaggio 8250785 countershaft is the intermediate shaft of the final drive, listed in the Piaggio catalog under the official name "ALBERO DI RINVIO" (COUNTERSHAFT). It is intended for Piaggio Free FL and Free PPTT 50 mopeds (historical catalogs 1998-2005) and the Vespa Sprint 50 2T (2014-2017, EMEA markets). It has a gearwheel and a straight-toothed pinion machined on the same body: it is the element that transfers motion from the engine output to the rear wheel axle. Product code 8250785, new original spare part.

✓ Strengths

• Original Piaggio spare part – same component assembled in the factory, catalog name "ALBERO DI RINVIO", code 8250785.
• Double gearing machined on the shaft – larger diameter gearwheel and smaller diameter pinion in a single piece, without added couplings (observed from the product photograph).
• Steel construction – metal body with ground cylindrical ends for bearing seats (observed from the product photograph).
• Guaranteed coupling – respects the dimensions and reduction ratio specified by the manufacturer, without adaptations.
• One code for two applications – the same item covers both Piaggio Free and Vespa Sprint 50 2T.

Who it's perfect for

This is the right spare part for those who are overhauling the reducer group of a Vespa Sprint 50 2T or the rear axle of a Piaggio Free and have found worn, chipped, or noisy gearing. It is suitable for both workshops replacing the entire transmission – often along with bearings and oil seals – and enthusiasts restoring a vintage 50cc moped who want an original part, not a rebuilt equivalent, to maintain the factory reduction ratio.

Frequently Asked Questions

Is this countershaft compatible with my Vespa Sprint 50?
The 8250785 countershaft is intended for the Vespa Sprint 50 2T NOABS E2 from 2014 to 2017, the version for Europe, Middle East, and Africa markets, in the "Reducer group" table. It is not intended for subsequent generation Sprint 50 4T models. If you have doubts about the year or trim, please provide your frame number and we will verify it.

Why does the same code apply to both the Piaggio Free and the Vespa Sprint 50?
Because the two vehicles share the same 50cc final drive scheme. In the historical Piaggio catalogs for the Free FL and Free PPTT, the part appears in the "Rear wheel axle" table, while on the Vespa Sprint 50 2T it appears in the "Reducer group" table: the catalog position changes, but the item is the same.

Is it an original Piaggio spare part or an aftermarket equivalent?
It is an original Piaggio spare part, not a rebuilt equivalent. The code 8250785 is the manufacturer's code, and the catalog name is "ALBERO DI RINVIO". There are also compatible aftermarket countershafts available: here you will find the Piaggio part, with the same dimensions and ratio specified at the factory.

What exactly does the supply include?
The supply is the single countershaft with its gears. Bearings, oil seals, shims, or circlips are not shown in the photograph; these are normally replaced separately during a reducer overhaul. If you need a complete list of parts to be replaced along with the shaft, contact us for more information: we will prepare a quote for the kit.
