Vertex 2-Stroke Piston Kits OEM equipment in KTM & HusqvarnaThe 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 cyclePiston skirts are coated with a hi-tech molybdenum disulphide for faster break-in timeNitride coating for increased piston lifePiston kits include piston, rings, wrist pin and cir-clipsKits are exact OEM replacementsTwo-stroke piston kits made from gravity cast aluminum alloy with 18% silicone content, which produces an extremely light but very strong pistonHigh compression pistons improve power and torque across entire rpm rangeMade in ItalyPiston Kit Vertex Yamaha YZ125 YZ125X 05-21 .5mm Oversize 54.45mm
