Description
Description
This genuine OEM Piston Kit (Size II) is a critical engine component designed to restore peak performance and compression to your 450cc engine. As an original equipment manufacturer part, it ensures perfect fitment and adheres to the strict tolerances required for high-performance motocross and cross-country racing.
This kit is compatible with a wide range of 450cc models from 2021 to 2023. It fits the KTM 450 SX-F, 450 XC-F, and 450 SMR (2021-2022). It is also designed for Husqvarna FC 450, FS 450, and FX 450 models from 2021-2022. Additionally, it fits GASGAS MC 450F and EX 450F models for 2021, 2022, and 2023, including the Troy Lee Designs and BT editions.
The kit includes the piston, high-quality piston rings, and circlips necessary for a complete top-end refresh. Size II pistons are typically used for cylinders that have seen some wear or are within specific factory tolerance ranges to maintain optimal oil film and compression.
Regular piston replacement is essential for maintaining engine reliability and preventing costly failures in high-revving four-stroke engines. We recommend following your service manual's hour intervals for inspection and replacement to ensure your motorcycle continues to deliver maximum power on the track or trail.
