Presentation: the "Curé head" performance
The TM / Vertex 4 ° piston is specifically designed for the drivers of the KZ (125cc in box) range. Its cap has an inclination of 4 degrees, a technical architecture that promotes optimal gas scan and more efficient combustion in the pre-combustion chamber.
-
Precision Manufacturing: Produced by Vertex, world leader in the competition piston, according to the extremely rigorous specifications of the TM Racing factory.
-
Surface treatment: Generally equipped with a molybdenum bisulf cover (MOS2) to reduce friction and facilitate break-in during the first minutes of use.
-
Fine segments: Equipped with a segment of 1 mm thick to minimize the mechanical drag while ensuring a perfect seal with high compression.
