The VERTEX top end piston set is specially designed for the 2-stroke engine of the Yamaha WR 125. This kit contains a standard size A replica cast piston with a bore size of 54.00mm. The piston diameter is 53.93 mm and therefore corresponds to the original dimensions for a displacement of 125 cc.
The VERTEX piston set is designed as a top end kit and includes all the necessary components for replacing the piston and piston rings. The use of cast aluminum alloy ensures a robust and durable construction that meets the requirements of the 2-stroke engine. The piston rings are made of steel and have a nitride coating to increase wear resistance and ensure a reliable seal in the combustion chamber.
This kit is suitable for replacement during maintenance or repair work and ensures a precise fit. The standard size A corresponds to the original manufacturer specifications, so no further adjustments to the engine are necessary. The combination of pistons and rings in one set allows for easy and efficient assembly.
The VERTEX top end piston set is part of the ENGINE GROUP and is delivered as a complete set. It helps restore engine performance and contributes to engine longevity by replacing worn or damaged components.
