YAMAHA YZ 125 2022 +1.00mm OVERSIZE 54.95mm SINGLE RING PISTON
Vertex pistons are manufactured using Low-Ex silicon aluminum alloys with 12%, 18%, or 21% silicon content depending on the application. Pistons are produced via gravity casting or hydraulic forging, followed by heat treatment in an automatic HT implant with solubilization by hot water quench. Machining is performed on the latest CNC machines and software using diamond tools to achieve specific surface finishes. Every Vertex piston undergoes rigorous manual and automatic quality control. Vertex pistons are coated with a special Molybdenum Bisulphite black coating to aid break-in and reduce friction. A new Phosphate Coating, following Formula One engine developments, offers increased hardness, light surface porosity, and superior Molybdenum Coating adhesion, doubling coating durability. This is a +1.00mm oversize 54.95mm single ring piston.

FULL DESCRIPTION
High-Performance Oversize Piston for Enhanced Engine Durability
Upgrade your engine performance with this precision-engineered Vertex +1.00mm oversize piston. Designed for riders who demand reliability and power, this 54.95mm single-ring piston is manufactured using advanced aluminium alloys and cutting-edge production techniques to ensure peak performance under intense riding conditions.
Advanced Manufacturing and Material Quality
Vertex utilizes high-quality Low-Ex (low expansion) silicon-charged aluminium alloys to maintain structural integrity and minimize thermal expansion. The production process involves sophisticated gravity casting or hydraulic forging, followed by a state-of-the-art heat treatment in an automated implant to refine the material structure. Each piston is precision-machined using CNC technology and diamond tools to achieve exacting tolerances and surface finishes tailored for optimal engine operation.
Durable Coatings for Reduced Friction
This piston features a dual-layer coating system designed to extend engine life and ease the break-in process:
- Phosphate Coating: Inspired by Formula One engine technology, this base layer provides increased hardness and superior surface adhesion.
- Molybdenum Bisulphite Coating: A specialized outer layer that significantly reduces friction inside the cylinder and protects the piston during the critical break-in period.
