Vertex Big Bore XL Piston Kit 84mm 305cc

Enhance the power and performance of your four-stroke engine with this premium Vertex Big Bore XL piston kit. Engineered for riders who demand reliability and increased output, this high-performance piston is built to handle the intense pressures and high-revving demands of modern off-road engines.

Vertex pistons are forged from high-quality 2618 aluminum alloy, providing exceptional structural integrity and heat resistance. To ensure smooth operation and long-term durability, each piston features a specialized Molybdenum Disulphide (MOS2) coating on the skirt, which aids in the break-in process and significantly reduces friction and wear.

Key Features:

• Increased Displacement: Designed as a Big Bore XL configuration (84mm) to increase engine capacity to 305cc.
• High Compression Ratio: Features a 13.3:1 compression ratio to maximize combustion efficiency and torque output.
• Forged Construction: Crafted from 2618 aluminum alloy for maximum strength and resilience under high-load conditions.
• MOS2 Skirt Coating: Advanced Molybdenum Disulphide coating reduces engine friction, minimizes wear, and assists with a quick, safe break-in period.
• Precision Engineering: Manufactured to exacting tolerances to reduce blow-by and oil consumption, ensuring your engine runs cleaner and more efficiently for longer.

Whether you are looking to revitalize a tired engine or seeking a competitive edge, this Vertex piston kit delivers the professional-grade quality required for serious performance builds.
