Description

If you're rebuilding the top end of your Kawasaki KX250F and looking for a performance boost, a high-compression piston like this one from JE Pistons is a solid choice. This piston is designed to increase the compression ratio to 14:1, which means more power and quicker throttle response when you get back on the track or trail. It's a single piston, so you'll need to order the correct quantity for your engine. JE Pistons are well-known in the racing world for their durable forged construction. This piston is forged from high-strength aluminum alloy, which makes it strong enough to handle the increased pressures of a higher compression ratio without adding unnecessary weight. The 14:1 compression ratio is a notable bump over stock, so you'll feel the difference in performance. It's important to ensure your engine's fuel system and tuning are set up to take advantage of this increased compression for optimal results. 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 any specific requirements for your engine build.
