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

Revainrating 1 out of 5

Very brittle! fits engine

Very fragile! This set bokeh into the piston ring tool during installation and I think most people will do it by hand. I've tried them too and no luck. I would only recommend buying a new piston with rings. The quality of the piston rings is much better and easier to change without breaking

Pros
  • parts
Cons
  • weight
