Vertex 2-Stroke Piston Kits OEM equipment in KTM & Husqvarna
The Vertex formula for delivering better on-the-track performance is simple ? precision equals performance. It all begins with precision engineering based on more than 50 years of experience in the design of OEM-quality and championship proven replacement pistons. The commitment to precision continues throughout the manufacturing process where every Vertex piston is given an advanced Molybdenum Disulphide (MOS2) coated skirt to aid break-in and a special Nitride coating for extended durability. Once manufactured, pistons pass through a rigorous manual and automatic quality control process to ensure only the highest quality level. It all adds up to replacement pistons that deliver more power, less noise and a longer life ? and that equals performance!

All pistons are heat treated with T-5 hardening and a tempering cycle
Piston skirts are coated with a hi-tech molybdenum disulphide for faster break-in time
Nitride coating for increased piston life
