Vertex Complete Top End Piston Kit, 44.97mm

Vertex VTK23430CD is a complete Race Evolution top-end kit, developed for riders who demand maximum performance, fast response, and true racing quality from their 2-stroke engine.

The Race Evolution series is derived directly from experience at world championship-level motocross and enduro, with a focus on reduced friction, higher rev capability, and improved power delivery.
The piston features a dedicated racing profile and uses a 0.8 mm piston ring for quicker response and more efficient combustion.
The advanced MoS₂ (molybdenum) coating reduces wear and ensures faster break-in, while the piston design optimizes the interaction between the cylinder and piston for smooth operation even under high load.
