🚀 High Performance 10x47mm Piston Rings for 66cc 80cc Motorised Bicycle Engines - Upgrade your Bike's Engine Efficiency! Review

You can grind the piston soap, wash and replace the rings and cylinder or just the rings, so multiple sets or rings are a must, adjust my piston just a ritual passage

Each ring has a different gap, poor finish on the surface of the rings and very poor quality rust on all rings. I am very disappointed.

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

Good quality rings. Fits well and is flexible enough to be pulled on easily. Extremely fast delivery all in all. As if he came from the other side of the world.
