Exhaust O-Ring 35x3mm for KTM 65 SX, Husqvarna TC 65, GasGas MC 65 - 0770350030
This genuine OEM Viton O-ring is designed specifically for the exhaust system of 65cc motocross bikes. It provides a high-temperature seal between the exhaust expansion chamber and the engine cylinder to prevent exhaust leaks and maintain peak engine performance.
This part is compatible with a wide range of models, including the KTM 65 SX (2002-2026), KTM 65 XC (2008-2009), Husqvarna TC 65 (2017-2026), and GasGas MC 65 (2021-2026). It also fits specialized racing models like the KTM 65 SXS from 2012-2015.
Made from high-quality Viton material, this 35x3mm O-ring offers superior resistance to heat and chemicals compared to standard rubber seals. Its durable construction ensures a long-lasting, airtight seal even under the extreme vibrations and temperatures of competitive racing.
We recommend replacing these O-rings whenever the exhaust pipe is removed for maintenance or if you notice oil residue leaking from the cylinder flange. Applying a small amount of high-temp silicone grease during installation can help seat the ring properly and prolong its service life.
