YAMAHA YZ 250 1996-1998 GRADE A 67.94mm TWIN RING PISTON

Vertex Grade A 67.94mm Twin Ring Piston

Experience superior engine performance and reliability with the Vertex Grade A 67.94mm Twin Ring Piston. Precision-engineered for high-performance applications, this piston is crafted using advanced materials and manufacturing techniques to ensure optimal durability and power output for your motorcycle engine.

Advanced Engineering and Construction

Vertex pistons are manufactured using exotic Low-Ex (low expansion) silicon-charged aluminium alloys. Through a sophisticated gravity cast or hydraulic forging process, the structural integrity of the metal is refined via a high-tech heat treatment cycle. This process ensures the piston maintains dimensional stability even under extreme operating temperatures.

Key Features

• Precision Machining: Produced using state-of-the-art CNC machinery and diamond-tipped tooling to achieve exacting surface finishes tailored to specific engine requirements.
• Enhanced Coatings: Features a Molybdenum Bisulphite black coating to assist in the break-in process and significantly reduce friction during operation.
• Phosphate Layering: Incorporates a specialised phosphate coating that increases surface hardness and provides superior adhesion for the Molybdenum layer, effectively doubling the coating durability.
• Quality Assured: Every piston undergoes a rigorous manual and automatic quality control inspection to ensure it meets the highest industry standards.

Whether you are performing a top-end rebuild or enhancing your engine for better performance, the Vertex twin ring design provides the consistent compression and heat dissipation required for demanding riding conditions.
