Description
Description
This primary gear nut is a critical component for securing the primary drive gear to the crankshaft or transmission shaft. As an authentic OEM part, it ensures a precise fit and maintains the structural integrity of your engine's internal drive system.
This part is compatible with a wide range of 85cc motocross models, including the KTM 85 SX (2018-2026), Husqvarna TC 85 (2018-2026), and GasGas MC 85 (2021-2026) in both 17/14 and 19/16 wheel configurations. It also fits the KTM Freeride E 660W (EU/US) 2025 models.
Constructed from high-strength steel, this nut is designed to withstand the high torque and vibration levels found within the engine casing. Its specific threading and locking properties help prevent loosening during intense riding conditions.
When replacing internal engine components, always use a torque wrench to meet the manufacturer's specified settings. It is recommended to inspect this nut whenever the primary drive or clutch assembly is serviced.
