Exhaust Control O-Ring 24x2mm for KTM SX/EXC/XC 1998-2026 - 0770240020

This genuine OEM O-ring is a critical sealing component for the exhaust control system, specifically designed for the power valve assembly. Measuring 24.00x2.00mm and manufactured from high-quality NBR70 rubber, it ensures a tight seal to prevent exhaust leaks and maintain optimal engine performance. Using original parts guarantees the precise tolerances required for your engine's internal components.

This versatile part fits an extensive range of models including the KTM 85 SX, 125 SX/XC, 150 SX/EXC/XC-W, 250 SX/EXC/XC, 300 EXC/XC/MXC, and 380 SX/MXC from 1998 to 2026. It is also compatible with Husqvarna TC 85/125/250, TE 150/250/300, and TX 125/300 models, as well as GasGas MC 85/125/250, EC 250/300, and EX 250/300 models across various years.

Constructed from Nitrile Butadiene Rubber (NBR70), this O-ring offers excellent resistance to heat, oil, and fuel common in two-stroke exhaust environments. Its precise dimensions guarantee a perfect fit, helping to regulate the exhaust valve timing and power delivery of your motorcycle. Replacing this seal prevents pressure loss that can lead to inconsistent throttle response.

Replacing worn O-rings during regular top-end maintenance or power valve cleaning is essential to prevent carbon buildup and sticking. Always ensure the seating surface is clean and lightly lubricated with a compatible grease before installation to avoid pinching or tearing the seal. Regular inspection of the exhaust control system helps maintain the longevity of your engine.
