Exhaust Silencer Rockwool 315g for KTM 250/300 EXC/XC-W 2011-2019 - 54805078315

This genuine OEM exhaust silencer rockwool is designed to maintain optimal performance and sound levels for your motorcycle's exhaust system. The 315g packing material effectively absorbs noise and heat, ensuring your silencer functions as intended by the manufacturer. Replacing worn packing is essential for maintaining engine backpressure and meeting noise regulations.

This part is compatible with a wide range of KTM and Husqvarna 2-stroke models from 2011 to 2019. It fits KTM 200 EXC, 250 EXC, 250 XC-W, 300 EXC, and 300 XC-W models, including TPI and Six Days editions. It is also suitable for Husqvarna TE 250, TE 250i, TE 300, and TE 300i models produced between 2011 and 2019.

High-quality rockwool provides superior thermal resistance and durability compared to aftermarket alternatives. Using the correct 315g weight ensures the silencer is packed to the precise density required for your specific engine displacement. This helps prevent the silencer body from overheating and extends the life of the exhaust components.

Regularly repacking your silencer is a vital part of 2-stroke maintenance, especially after heavy use or exposure to water. Fresh packing restores the crisp exhaust note and prevents power loss associated with clogged or burnt-out material. It is recommended to inspect the silencer packing every 30-50 hours of riding time.
