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.

- Installation and recommendations

  1. Cylinder measurement: Before any order, measure your cylinder by a professional to choose the adapted piston coast (usually a set of 0.06 mm is recommended on a KZ).

  2. MANAGEMENT SENS: The arrow engraved on the piston head must imperatively be directed towards the exhaust light.

  3. Holding of the segment: Make sure the segment positioning lug is well placed to prevent the segment from clinging into a transfer.

  4. BROGING: Careful rashing of 15 to 20 minutes is needed to ensure the longevity of the piston and segment tightness.


💡 Michel's trick

"The 4 ° piston is the standard for modern KZ engines. The trick: Never confuse a 4 ° piston with a piston 'flat' (0 °). If you mount a 4 ° piston under a dome designed for a flat piston, you will destroy your engine in seconds! My Pro Council: Always note the number of hours of your piston on your setting book. In Kz, to keep the top performances, we change the piston every 8 to 10 hours. Beyond that, the risk of breakage of the segment or ovalization of the cylinder is growing seriously. "


❓ FAQ SEO (Frequently Asked Questions)

Q: Is this piston compatible with the new TM R2 engine?

A: Yes, the 4 ° piston remains the reference for TM's current KZ motor architectures, including R1 and R2 models.

Q: What piston pin is used?

A: It uses an axis of 15 mm, standard for the majority of the engines of this category.

Q: Is it a piston poured or forged?

A: The Vertex Pistons for TM are high-tech forged models, offering a structural strength much greater than standard cast models to support the 15,000 rpm.
