JE Pistons Yamaha YZ 250F 14 to 1 Piston Kit

If you're looking to rebuild the top end of your 2005-2013 Yamaha WR250F or YZ250F, a new piston is a key component. This piston kit from JE Pistons is designed to replace the original and offers an updated 14 to 1 compression ratio, which can help increase power output when paired with appropriate tuning.

JE Pistons is known for making well-built internal engine components. This particular piston is forged from high-grade aluminum, a strong material that's also lightweight, helping to reduce reciprocating mass in the engine. The 14 to 1 compression ratio is a notable bump over stock, meaning you'll want to ensure your fuel and ignition systems are set up to take advantage of it for optimal results. This kit includes the piston, rings, wrist pin, and clips, so you have the essential parts needed for the installation.

Keep in mind that this piston is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper fitment and assembly procedures.
