Description
Description
This genuine OEM Overload Spring is a critical component of the exhaust control system on 2-stroke engines. It ensures the power valve mechanism operates with the correct tension, allowing for smooth power delivery across the RPM range. As an original part, it guarantees the precise spring rate required for optimal engine performance and reliability.
This spring fits an extensive range of models including the KTM 85 SX, 125 SX/EXC, 150 SX/EXC, 250 SX/EXC/XC, and 300 EXC/XC/MXC from 1994 to 2023. It is also compatible with Husqvarna TC 85, TC 125, TE 150/250/300, and TX 125/300 models, as well as GasGas MC 125 models from 2021-2023. It covers both carbureted and TPI/fuel-injected versions.
Constructed from high-quality spring steel, this component is designed to withstand the high temperatures and constant mechanical stress found within the exhaust assembly. Replacing a worn or fatigued overload spring is essential for maintaining the responsiveness of your motorcycle's power valve and preventing performance drops.
Regular inspection of the exhaust control mechanism is recommended during top-end rebuilds or routine maintenance. Ensure the spring is seated correctly within the assembly to prevent binding or irregular power delivery during acceleration.
