Brake drum rear 10 inch - SCOOTOPIA reinforced - PX (1988-), T5 - felt ring Ø31,5 mm

The performance of Vespa large-frame setups is increasing - at the same time, many original brake drums are now several decades old. This combination is critical, as the rear drum not only brakes, but is also a central component of the power transmission. In order to offer a resilient solution for powerful engines, this reinforced rear brake drumwas developed by Jockeys Pit Stop together with Scootopia.

10 inch rear SCOOTOPIA reinforced PX from 1988 Felt ring Ø31.5 mm M8 bolts 10.9 high-strength

What makes this drum better

Reinforced at typical weak points - designed for modern, high-performance setups.

Wheel bolts as M8 screws instead of special solutions → common rims can be mounted cleanly.

Suitable bolts are included: M8 pan-head hexagon socket in 10.9 (high-strength).

Useful upgrade compared to old original drums or fluctuating reproduction quality.

Important note: this version (Ø31.5 mm / felt ring)

Suitable for PX models from 1988 onwards: felt ring on the outside, the shaft seal sits inside the gearbox.

The outer seat is not polished and can be rough in places - therefore not the right choice if a classic oil seal is to be used on the outside.

Suitable for Vespa PX (1988-) and T5 with internal oil seal.

Fitting tip: Tightening torques

Rear axle nut: 100-110 Nm

Wheel bolts (M8): 20-22 Nm

Tip for Lusso models: Use a double washer

On many Lusso models, the washer under the axle nut is relatively thin ex works. This can lead to the nut loosening more easily - recognisable by a locking cage that does not fit properly. The split pin prevents worse, but minimal play can "jam" the nut and damage the drum teeth.

Practical solution: fit two washers.

The split pin may have to be pre-bent slightly - in return, the drum sits more firmly and is usually easier to dismantle later.

Background knowledge: Brake drum types for Vespa Largeframe

With the introduction of the Vespa GL (around 1962), a brake drum type was established that is still used today in a similar design, with the exception of the GS160/SS180 and COSA models.

1962-1984: Ø27 mm oil seal running surface, castellated nut + split pin - 75-90 Nm

1984-1988: Ø30 mm oil seal face, hexagon nut + cage + split pin - 90-110 Nm

1988-today: Ø31.5 mm (unground) for felt ring, internal oil seal - 90-110 Nm

The larger flange diameter (Ø27 → Ø31.5) significantly increases stability. With Ø27 mm drums, the flange can expand if the tightening torque was too low. Typical symptom: The rear wheel keeps coming loose despite the nut being correctly tightened. The only thing that helps in this case is to replace it in good time before the main shaft and gearing are damaged.

Upgrade and downgrade: combine old and new

Upgrade old to new (Ø27 mm → Ø30 mm):

The more stable Ø30 mm drum of the PX Lusso (1984-1988) can be used on older models if the matching Ø30 mm oil seal and the matching washer of the models from 1984 onwards are also used.

Downgrade new to old (Ø31.5 mm / felt ring → outer shaft seal):

The drum from 1988 onwards does not have a ground running surface on the outside and is therefore unsuitable for an external shaft seal. An internal shaft seal and a felt ring on the outside are used here ex works.

If you want to convert to an external shaft seal, use the Ø30 mm Lusso drum (1984-1988) as a basis. Tip: If the internal shaft seal is omitted, close the drip hole in the housing.

Note on the surface

The surface is to be understood as a protective coating: visually good, but not as a flawless "show" coating.

Conclusion

The reinforced SCOOTOPIA rear brake drum was developed by Jockeys Pit Stop together with Scootopia to offer a resilient alternative to old original drums. In the Ø31.5 mm felt ring version, it fits PX (1988-) and T5 with internal shaft seal. Thanks to the enclosed M8 pan-head hexagon socket screws (10.9), the rim assembly is designed directly to a high-strength standard.
