Asso Piston (55.6mm) for ET3 for Scooters & Mopeds

Asso Piston Built for ET3 Scooters and Mopeds

This 55.6mm Asso piston is made for ET3 scooters and mopeds. It helps the engine run properly and keep its performance. You'll find it among our piston and piston ring options for scooters, where it does an important job of sealing the combustion chamber. Swapping out worn parts can help avoid problems such as smoke, heavy oil use, and poor compression.

Signs It Needs Replacing

Consider changing this piston if you see more smoke or notice it using more oil than before. Worn piston rings can drop engine compression, which hurts how the machine performs overall. Getting the correct piston diameter and pin size matters for a snug, proper fit.
