YZ 125 2005-2021 TOP END KIT SINGLE RING RACE EVOLUTION PISTON
Vertex top-end kits include piston, rings, circlips, piston pin, base gaskets, head o-rings and piston pin bearing. All pistons are heat treated with T-5 hardening and a tempering cycle. New T-box forgings and DLC coated wrist pins on forged pistons with highest compression ratios for increased strength and performance. Piston skirts are coated with a hi-tech molybdenum disulphide for faster break-in time. Nitride coating for increased piston life. Top end piston kit includes piston, rings, pins, circlips, base gaskets, head o-rings and wrist pin bearing when applicable. Kits are exact OEM replacements. Two-stroke piston kits made from gravity cast aluminum alloy with 18% silicone content, which produces an extremely light but very strong piston.

FULL DESCRIPTION
Vertex Race Evolution Top End Piston Kit
The Vertex Race Evolution Top End Kit provides a complete, high-performance solution for restoring your engine's power and reliability. Designed as an exact OEM replacement, this kit contains all the essential components required for a professional-grade top-end rebuild, ensuring precision fitment and factory-standard performance.
Each piston is engineered from a high-quality gravity cast aluminum alloy with 18 percent silicone content, resulting in a component that is exceptionally lightweight yet maintains superior structural strength. To ensure maximum durability, every piston undergoes a T-5 hardening and tempering heat treatment process.
Key Features
- Advanced Construction: Features new T-box forgings and DLC coated wrist pins on forged pistons to maximize strength and compression ratios.
- Enhanced Durability: Equipped with a nitride coating to significantly extend the service life of the piston.
- Optimized Break-in: Piston skirts are finished with a hi-tech molybdenum disulphide coating, which reduces friction and allows for a faster, safer break-in period.
- Complete Kit: Includes everything needed for the job: piston, rings, piston pin, circlips, base gaskets, head o-rings, and a wrist pin bearing where applicable.
- Race Proven Engineering: Vertex two-stroke pistons are widely recognized for their quality, with specific replica models supplied directly to major manufacturers as original equipment.
