VERTEX Piston Race Evolution (ref. 23621C) — Cast aluminum piston designed for motocross riders seeking a reliable replacement part during engine preparation. Suitable for 100 cm³ blocks such as the KAWASAKI KX100 (1997, 2000, 2013), it adheres to the oversize bore dimensions "C" for precise fitting and controlled break-in.
This Race Evolution piston plays its role in thermal reliability and mechanical integrity in off-road use. Its size and finish facilitate adjustment to the oversize bore, limiting unwanted play and contributing to a consistent engine response. Ideal for maintenance or engine rebuild operations on the KX100, it integrates with the listed components for a clean and secure reassembly. Follow the installation recommendations and break-in procedures to achieve lasting performance on the track.
