Piston Pin Needle Bearing for KTM/Husqvarna 250/300 1994-2026 - 54430034000

This is an authentic OEM Piston Pin Needle Bearing (KBK 18x22x20), a critical component for the crankshaft and piston assembly of high-performance 2-stroke engines. It ensures smooth rotation of the piston pin within the connecting rod, significantly reducing friction and heat during high-RPM operation. As a genuine factory part, it guarantees the precise tolerances and superior durability required for racing and off-road conditions.

This bearing features extensive compatibility across KTM, Husqvarna, and GasGas 2-stroke models. It fits KTM 250 and 300 SX, XC, EXC, and XC-W models from 1994 to 2026, as well as the Freeride 250 R and older 380 SX/MXC models. It is also compatible with Husqvarna TC, TE, and TX 250/300 models (2014-2026) and GasGas EC, EX, and MC 250/300 models (2021-2026).

Constructed with high-grade steel rollers and a robust cage, this bearing is engineered to withstand the intense pressures and temperatures of the combustion chamber. Replacing this bearing is a vital step during any top-end rebuild to prevent premature wear on the connecting rod and ensure the longevity of your engine's rotating assembly.

For optimal performance, ensure the bearing is thoroughly coated with clean 2-stroke oil before installation. It is highly recommended to replace the needle bearing every time the piston is serviced to maintain peak engine reliability and prevent catastrophic failure.
