Kawasaki KX 250 F (KX 250 N) [2004-2005] - Big Bore forged pistons

VERTEX Big Bore forged piston for Kawasaki KX 250 F

The VERTEX Big Bore forged piston is designed for the Kawasaki KX 250 F (KX 250 N) built in 2004-2005. As a forged aluminum version, it offers a defined basis for repairing or building the engine with an enlarged bore diameter.

Function and execution

The piston is a big-bore version with a diameter of 78.96 mm. The oversize is +2.00, the specified bore diameter is 79.00 mm. The piston compression corresponds to the standard version and thus supports a selection based on near-production compression.
