This genuine OEM Viton O-ring (20x2mm) is a high-quality sealing component designed for precision motorcycle assemblies. It serves as a critical seal within the clutch control, clutch housing, and transmission systems to ensure leak-free operation and optimal performance.

Compatible with an extensive range of models including KTM 65 SX (2009-2026), 790 Adventure and Duke (2018-2020), 890 Adventure, Duke, and SMT (2020-2026), and the 1390 Super Duke and Super Adventure series (2025-2026). It also fits Husqvarna Norden 901, TC 65, and GasGas MC 65 models.

Constructed from premium Viton material, this O-ring provides superior resistance to high temperatures, oils, and various chemicals. Its robust design is engineered to withstand the rigorous demands of both off-road racing and long-distance touring.

Replacing worn O-rings during routine maintenance is essential for preventing hydraulic fluid loss or oil seepage. We recommend applying a light coat of compatible lubricant during installation to ensure the seal seats correctly without damage.
