YAMAHA YZF 250 2008-2013 GRADE A 76.95mm HIGH COMPRESSION 13.9:1

Vertex High Compression Four-Stroke Piston

Maximize your engine performance with this premium Vertex high compression piston. Engineered for riders who demand reliability and power, this piston is designed to withstand the extreme internal pressures of modern high-performance four-stroke engines. By optimizing the compression ratio, this component helps deliver improved throttle response and increased power output throughout the rev range.

Advanced Materials and Engineering

Vertex manufactures these pistons using high-quality 2618 aluminum alloy. This material choice provides the ideal balance of strength and lightweight construction, ensuring durability under heavy racing conditions. Every piston features a specialized Molybdenum Disulphide (MOS2) coating on the skirt, which assists during the break-in process and actively works to reduce friction and wear over the life of the engine.

Precision Sizing for Peak Efficiency

This Grade A piston is manufactured with strict tolerances to ensure a perfect fit within your cylinder. Proper sizing is essential for maintaining engine compression, preventing oil consumption, and eliminating blow-by. By choosing the correct Vertex piston size, you ensure that your engine operates at its maximum potential while maintaining consistent performance across all conditions.
