Vertex Piston 24449A piston kit

VERTEX PISTON 24449A Pro HC Piston Kit for Yamaha YZ 450 F

Elevate the heart of your Yamah´s engine with the VERTEX PISTON 24449A Pro HC Piston Kit, the ultimate upgrade for riders demanding maximum performance and unrivaled reliability from their top end. Engineered for the serious competitor and discerning enthusiast, this piston kit is a direct result of Vertex´s world-renowned expertise in high-performance engine components, delivering a tangible boost in power and durability.

The 24449A is a Pro High-Compression (Pro HC) piston, a pinnacle of performance developed using Vertex´s advanced forging technology. By increasing the engine´s compression ratio, this kit delivers a noticeable and significant improvement in power and torque across the entire RPM range. Experience sharper throttle response, stronger acceleration out of corners, and a more potent powerband that will give you a competitive edge on the track or trail.

Crafted from a premium 2618 aluminum alloy, each piston is forged—not cast—to achieve superior strength and durability. This process ensures the piston can withstand the extreme stresses of high-performance racing and aggressive riding, offering peace of mind and long-lasting service. To further enhance its resilience, every piston undergoes a meticulous T-5 hardening and tempering heat treatment cycle. This critical step guarantees the piston´s structural integrity and long-term stability under the highest temperatures and pressures found in a modern four-stroke engine.

To ensure optimal performance right from the start, the piston skirts feature a high-tech Molybdenum Disulphite (MoS2) coating. This advanced, friction-reducing layer promotes a faster and more efficient break-in period, allowing you to get back to riding sooner. More importantly, this coating continues to protect against scuffing and wear throughout the piston´s life, significantly extending the service interval of your engine´s top end.

This comprehensive kit provides a complete top-end solution, including the high-performance piston, precision-engineered rings, a durable wrist pin, and secure circlips, all designed to work in perfect harmony. Upgrade your engine with the same quality and technology trusted by professional race teams and OEMs worldwide. Choose the VERTEX PISTON 24449A kit for a stronger, more powerful, and more reliable engine.
