Description
This OEM spring washer (DIN0137-B12) is a critical component of the ignition system, specifically designed to maintain tension and prevent the flywheel nut from loosening due to engine vibration. As a genuine factory part, it ensures the precise fit and mechanical reliability required for high-performance powersports engines.
This part fits an extensive range of motorcycles, including the KTM 450 and 500 EXC-F, SX-F, and XC-F from 2012-2026, as well as legacy models like the KTM 620 and 660 from the 1990s and early 2000s. It is also compatible with Husqvarna FE 450/501, FC 450, and FS 450 models (2014-2025), and GasGas MC 450F and EX 450F models (2021-2025). Specialized machines such as the KTM 450 Rally Replica and various Husaberg-era FE/FS models are also supported.
Constructed from high-quality spring steel, this B12 wave washer provides consistent axial pressure to secure the rotor assembly. Replacing this washer whenever the flywheel is removed is a recommended maintenance practice to prevent hardware failure and ensure the crankshaft assembly remains properly torqued during operation.
