Athena 03-05 Husqvarna SMR 250 Stock Bore Complete Cylinder Kit

This Athena cylinder kit for your 2003-2005 Husqvarna SMR 250 gives you everything you need to replace the stock cylinder and piston. You get a new, standard-bore aluminum cylinder, a complete piston assembly with the piston pin and rings, and all the necessary gaskets to get the job done. This kit is designed to match the original performance of your SMR 250, ensuring your engine runs smoothly and reliably.

Athena uses a lightweight aluminum cylinder for this kit, which helps with heat dissipation. The cylinder barrel features a nickel-silicon coating, a tough surface that's known for its durability and low friction. The piston itself has been designed with reduced friction in mind, which contributes to the overall smoothness and efficiency of your engine. This combination of materials and design helps maintain the original feel and power delivery of your motorcycle.

When you're rebuilding the top end of your engine, getting all the right components in one package makes the job much easier. This kit provides the core pieces needed to get your SMR 250 back to its factory specifications. Remember that this part is not CARB approved and cannot be shipped to California.
