Vertex Cast Race Piston Kit for 85cc 2-Stroke Engines

Unleash the full potential of your 85cc 2-stroke engine with the high-performance Vertex Cast Race Piston Kit. Engineered with Vertex technology and a specialized race shape profile, this kit delivers exceptional power and reliability for competitive riding and demanding conditions.

Description

Optimize your engine's performance with the precision-engineered Vertex Cast Race Piston Kit. Designed specifically for 85cc 2-stroke engines, this kit includes a piston, rings, wrist pin, and circlips, providing a complete solution for rebuilds or upgrades. Each piston is meticulously heat treated with a T-5 hardening and tempering cycle, ensuring superior strength and durability under extreme operating temperatures. The advanced Molybdenum Disulphite coating on the piston skirts significantly reduces friction, promoting faster break-in times and extending the overall lifespan of your engine. Crafted from a gravity cast aluminum alloy with an 18% silicone content, this high-performance cast piston achieves an incredibly light yet robust construction, vital for rapid engine response and sustained power output. With a standard compression ratio and a bore size of 48.50mm (piston diameter 48.47mm), this Vertex piston kit is built to meet the rigorous demands of racing and high-performance applications, ensuring consistent, reliable power delivery.

Features & Highlights

• Advanced Cast Race Profile: Developed with Vertex technology, the race-shaped piston profile is optimized for maximum power output and efficiency in 85cc 2-stroke engines.
• Enhanced Durability & Longevity: Each piston undergoes a T-5 hardening and tempering heat treatment cycle, significantly increasing its strength and resistance to wear for prolonged engine life.
• Superior Friction Reduction: High-tech Molybdenum Disulphite coating on the piston skirts ensures faster break-in, minimizes wear, and boosts overall piston life by reducing operational friction.
• Lightweight & Robust Construction: Manufactured from gravity cast aluminum alloy with an 18% silicone content, providing an extremely light yet exceptionally strong piston for agile performance.
• Complete Kit for Convenience: Includes everything needed for a comprehensive piston replacement: the piston, high-quality rings (nitride coated steel), a wrist pin, and circlips.
