Genuine Roughhouse 50 / Rattler 50 OEM Piston

Replacement OEM Piston for Genuine RoughHouse 50 and Rattler 50 Scooters

This OEM piston is made to suit the Genuine RoughHouse 50, RoughHouse 50 SP, Rattler 50, and Black Cat 50 scooters. Built as a spare for the 50cc 2-stroke PGO-based engine, it lines up with the original mounting points so no modifications are needed. It sits among the Genuine scooter parts range and is a direct option for swapping out a worn piston on these models.

Build and Layout

The piston is cast from aluminum and uses a two-ring crown shape meant to support engine output. The wrist pin bore and ring locating features are already machined, so the piston is easier to set up during fitting. The dimensions follow those of the factory component.

Fitting and Swap-Out

Piston replacement is a routine job for scooter owners, particularly when the engine begins to run poorly. Seating the new piston correctly is key to keeping the engine running as it should. Because it is made for PGO-based engines, it can take the place of the old piston directly.
