JE Pistons Kawasaki KX250F 17 13.7 to 1 Piston Single

This is a JE Pistons forged piston designed for the 2017 Kawasaki KX250F. It features a 13.7 to 1 compression ratio, which is an updated spec from the stock compression, offering improved performance for riders looking to get more out of their engine. JE Pistons are well-known for their durable construction and precise manufacturing, making them a solid choice for engine rebuilds or performance upgrades.

Forged pistons like this one are built from a single piece of aluminum that is heated and hammered into shape, creating a stronger and more resilient piston than cast alternatives. This process results in a piston that can better withstand the higher pressures and temperatures associated with increased compression and performance tuning. The 13.7:1 compression ratio is a notable increase, meaning you'll want to ensure your fuel system and ignition timing are properly set up to take advantage of the added power without causing detonation.

When rebuilding your KX250F's engine, using a high-quality forged piston like this JE Pistons unit is crucial for reliability and performance. Remember that this piston is not CARB approved and cannot be shipped to California. Always consult your service manual for proper installation procedures and torque specifications.
