Review on πŸš€ High Performance 10x47mm Piston Rings for 66cc 80cc Motorised Bicycle Engines - Upgrade your Bike's Engine Efficiency! by Eric Nelso

Revainrating 1 out of 5

Good value for the engine

You can grind the piston, wash with soapy water and replace the rings and cylinder or just the rings, so must have multiple sets or rings, only fits my piston. rite

Pros
  • Piston and accessories
Cons
  • Retrofittable
