Piston Pin Wire Lock Ring for KTM Husqvarna GasGas 250/300 - 54030074000

This genuine OEM wire lock ring is a critical component for your engine's top end, specifically designed to secure the piston pin in place. It prevents the pin from sliding out and causing catastrophic damage to the cylinder walls or crankshaft assembly. As an original part, it offers the precise tension and fitment required for high-performance two-stroke engines.

Compatible with an extensive range of motorcycles, this part fits KTM 250, 300, and 380 models including the SX, EXC, XC, and XC-W from 1998 through 2026. It is also the correct fitment for Husqvarna TC 250, TE 250/300, and TX 300 models (2014-2026), as well as GasGas EC, EX, and MC 250/300 models (2021-2026). This includes specialized versions such as the TPI, Six Days, Erzbergrodeo, and Champion editions.

Constructed from durable spring steel, the C18x1.5 ring is engineered to withstand the intense heat and vibration of the combustion chamber. It is a standard practice to replace these lock rings whenever the piston is removed to ensure maximum retention. Using genuine OEM hardware is the best way to maintain the factory reliability of your powersports vehicle.

During installation, take care not to over-stress the wire ring, as this can lead to a loss of tension. Ensure the ring is fully clicked into the piston groove and that the gap is positioned correctly according to your service manual. Proper installation is key to preventing engine failure during operation.
