§ 02 / About this part
What it is
Vertex piston kit Ø66.40 A to fit Gas Gas EC250 (2002–2014, 2018–2019); Rieju MR250 (2021); TM Racing CROSS250 (1995–1999); TM Racing ENDURO 250 2T (1995–1999).
This top-end component sits at the centre of your engine's combustion cycle. It requires regular replacement to maintain peak compression and prevent skirt fatigue. Most workshop manuals specify replacement intervals based on race hours or visible wear on the coating. The specific sizing increments allow you to match the piston to your cylinder's actual bore diameter as it wears over time. Each kit includes the necessary rings, wrist pin, and circlips for a complete top-end rebuild. Always verify your ring end gap and ensure the piston crown arrow points toward the exhaust port during assembly.
