FULL DESCRIPTION
Vertex High-Performance Four-Stroke Piston
Maximize the power and longevity of your engine with the Vertex four-stroke piston. Engineered for riders who demand reliability and peak performance, this piston is forged from high-quality 2618 aluminum alloy. This advanced material composition provides the strength necessary to withstand the extreme pressures and heat generated by modern high-performance engines.
Precision Engineering for Optimal Performance
Vertex is renowned for their meticulous attention to detail. This Grade C piston features a 78.98mm diameter and a 13.9:1 standard compression ratio. By offering specific sizing variations, Vertex ensures that your piston can be perfectly matched to your cylinder tolerances. This precise fit is essential for maximizing compression, increasing horsepower, and significantly reducing oil consumption and blow-by.
Advanced Surface Technology
To ensure a smooth operation from the very first start, every Vertex piston features a specialized Molybdenum Disulphide (MOS2) coating applied to the piston skirt. This coating serves two vital purposes: it assists in the critical break-in process and provides a permanent layer of friction reduction to minimize wear during high-RPM operation.
Key Features
- Forged from high-strength 2618 aluminum alloy for superior durability.
- MOS2 skirt coating to reduce friction and improve break-in efficiency.
- Designed to handle the rigorous demands of modern four-stroke engine platforms.
- Precision sizing to ensure a perfect cylinder-to-piston seal.
