Piston Kit Gr. I (Size A) for KTM 150 & Husqvarna 150 2020-2023 - 51730007010 I

This genuine OEM Piston Kit Gr. I (Size A) is designed to restore the engine performance and compression of your 150cc two-stroke motorcycle. As an original equipment manufacturer part, it ensures perfect fitment and adheres to the strict tolerances required for high-performance enduro riding. The kit includes the piston, rings, wrist pin, circlips, and a complete set of gaskets for a top-end rebuild.

This kit is compatible with the 2023 KTM 150 EXC and XC-W, as well as the 2020-2022 KTM 150 EXC TPI and XC-W TPI models. It also fits Husqvarna TE 150 and TE 150 Heritage models from 2023, and the TE 150i models from 2020 to 2022. This covers both European and US market specifications for these years.

Engineered for durability, the piston features a specialized coating to reduce friction and heat buildup within the cylinder. Using a Size A (Group I) piston is essential when your cylinder bore is within the original factory specifications to maintain optimal clearance. This complete set provides all the components needed to maintain the reliability of your fuel-injected engine.

For best results, we recommend measuring your cylinder bore before installation to confirm that Group I is the correct size for your engine. Always follow the manufacturer's torque specifications and ensure all gaskets are properly seated to prevent leaks. Regular top-end maintenance is key to preventing engine wear in demanding off-road conditions.
