This OEM Lock Washer VSK 18 is a critical safety component designed to prevent fastening nuts from backing off under high-vibration conditions. It is used in several key engine assemblies, including the crankshaft, ignition system, and clutch, ensuring the structural integrity of your motor. As a genuine factory part, it provides the exact fitment and material strength required for high-performance engines.

Compatible with an extensive range of motorcycles including KTM 250/300 EXC, XC, SX, and XC-W models from 1994 to 2026. It also fits the KTM 690 Enduro R, SMC R, and Duke; Husqvarna 701 Enduro, Supermoto, Vitpilen, and Svartpilen; and GasGas ES 700 and SM 700 models. This part is also found on various 250/450 SX-F, EXC-F, and SMR models across the KTM, Husqvarna, and GasGas lineups.

Manufactured to exact factory specifications, this lock washer features a specialized tensioned design that creates a reliable mechanical lock. This prevents critical components like the crankshaft nut or clutch hub from loosening during operation, which is essential for maintaining engine timing and power delivery.

When performing engine maintenance or clutch service, it is highly recommended to replace lock washers rather than reusing old ones. Reusing a deformed washer can lead to component failure or loose nuts, potentially causing significant internal engine damage. Always follow factory torque specifications during installation.
