YAMAHA YZF 250 2005-2007 WRF 250 2001-2014 GRADE A 76.95mm STD COMPRESSION 12.5:1

Vertex High-Performance Four-Stroke Piston

Upgrade your engine's reliability and output with this premium Vertex four-stroke piston. Engineered for demanding riders who require consistent power and durability, this piston is designed to withstand the high pressures and extreme conditions found in modern high-performance engines.

Vertex pistons are forged from high-quality 2618 aluminum alloy, providing a superior strength-to-weight ratio compared to cast alternatives. This robust construction ensures long-term integrity under the stress of competitive riding and heavy use.

Key Features

• Precision Forged Construction: Manufactured from 2618 aluminum alloy for maximum durability and resistance to engine stress.
• MOS2 Skirt Coating: Each piston features a unique Molybdenum Disulphide (MOS2) coating on the skirt. This specialized layer assists during the break-in process while actively reducing friction and overall wear.
• Optimized Performance: Engineered to provide a standard compression ratio of 12.5:1, balancing efficient power delivery with engine longevity.
• Exact Sizing: This Grade A piston is manufactured to precise tolerances (76.95mm), allowing for a perfect cylinder fit that maximizes power, reduces blow-by, and minimizes oil consumption.
• Advanced Design: Vertex utilizes proprietary piston profiles designed to optimize combustion chamber efficiency and enhance throttle response.

Choosing a Vertex piston ensures that your engine receives the benefit of years of research and development in off-road racing technology. Whether you are performing a routine rebuild or looking to restore peak performance, this piston provides the quality and consistency required for professional-grade engine maintenance.
