Wiseco 2015 Kawasaki KX450F 12.8:1 CR Piston

If you're rebuilding the top end of your 2015 Kawasaki KX450F, this Wiseco forged piston kit is a solid choice. It's designed to replace the stock piston and offers a 12.8:1 compression ratio, which means you'll get a noticeable bump in power and throttle response compared to a stock setup. Wiseco has been making performance parts for a long time, and their forged pistons are built to handle the demands of modern 4-stroke engines.

What sets this piston apart is the forged material. Instead of casting, the aluminum is heated and hammered into shape, which creates a much stronger and more durable part. This improved tensile strength helps the piston stand up to higher compression and heat, giving you a longer service life. Wiseco machines these pistons to tight tolerances right here in the USA, ensuring a good fit and optimal performance. This kit comes complete with the piston, high-quality rings, wrist pin, and circlips, so you have everything you need for the installation.
