Description
This genuine OEM Power Valve Auxiliary Spring is a critical component for tuning the exhaust control system on your 2-stroke engine. The "Hard Green" tension allows riders to customize the power delivery, typically providing a more linear and controlled opening of the power valve for better traction.
Compatible with an extensive range of 250cc and 300cc models from 2005 to 2023. It fits KTM 250/300 EXC, SX, XC, and XC-W models, Husqvarna TC 250, TE 250/300, and TX 300 models, as well as GasGas EC, EX, and MC 250 models. This includes TPI, Heritage, and Six Days editions.
As an authentic factory part, it ensures perfect fitment and reliable performance under high-heat conditions. Swapping the auxiliary spring is one of the most effective and cost-efficient ways to adjust your bike's power hit and throttle response to suit different terrain or riding styles.
Installation is straightforward and involves accessing the power valve adjustment housing on the side of the engine. It is recommended to inspect the spring for wear or fatigue during regular top-end maintenance to maintain consistent engine performance.
