Equip your mini-racer for the holeshot with the L.A. Sleeve FL5550, a premium solution for KTM 65 SX engine restoration. Constructed from high-strength chrome-moly alloy, this sleeve provides a resilient, low-friction surface that handles high-revving heat better than standard replacements. The precision-dimensioned ports are cut to exact specs, facilitating a trouble-free alignment with your engine's original layout to keep power delivery crisp and consistent.
Achieve a rock-solid engine foundation thanks to the centerless-ground outside diameter, which guarantees an airtight fit into the cylinder casting. Tailored for the 45.00mm standard bore, this component allows for a custom bore and hone post-installation, ensuring a perfect mechanical marriage between the sleeve and your piston. Shop Cheetah's Powersports for the FL5550 and give your KTM the durability it needs to dominate the track.
