O-Ring 25x2mm for KTM, Husqvarna & GasGas 125-300 fits 1994-2026 - 0770250020

This genuine OEM O-ring (25.00x2.00 mm) is a critical sealing component designed for high-performance powersports engines. It is primarily used within the crankshaft and countershaft assemblies to ensure airtight and oil-tight seals, preventing leaks and maintaining internal pressure.

This versatile part is compatible with an extensive range of models from 1994 to 2026. It fits KTM 125, 150, 200, 250, and 300 SX, EXC, XC, and XC-W models, as well as Husqvarna TC, TE, and TX series. It is also used in GasGas MC and EC 125/150 models and the KTM Freeride 250 R.

Constructed from high-quality NBR 70 nitrile rubber, this O-ring provides superior resistance to heat, engine oil, and fuel. Its precise dimensions and material hardness are engineered to withstand the rigorous vibrations and temperatures found in motorcycle transmissions and crankcases.

For a successful repair, always inspect the surrounding components for wear when replacing seals. We recommend lubricating the O-ring with a small amount of clean oil before installation to ensure it seats correctly without tearing or twisting.
