Product Details

If you're looking to get more out of your KTM 250 SX-F, EXC-F, or similar Husqvarna or Husaberg model, this Wiseco forged piston kit is a solid option. It's designed to replace the stock piston with a unit that offers a higher compression ratio, specifically 13.9:1, which can lead to improved power output. This kit is built for specific 4-stroke powersports engines, ensuring it's tailored to your bike's needs.

Wiseco makes these pistons using a forging process, which results in a well-built part with improved tensile strength compared to cast pistons. This means it's designed to handle the demands of performance riding and offer a good service life. The dedicated forgings also help optimize the strength-to-weight ratio, keeping things balanced. Everything you need for the installation, including high-quality piston rings, wrist pin(s), and circlips, comes included in the kit. These pistons are forged and machined right here in the USA.

This kit is designed for a standard bore and is a direct replacement for a range of KTM, Husqvarna, and Husaberg models from the mid-2010s. Keep in mind that this part is not CARB approved and cannot be shipped to California.
