Manufactured in Italy, Vertex, the premier brand of OEM replacement pistons, is the OEM supplier to KTM and numerous European motorcycle and go-kart manufacturers.

Easing the repair process by saving time and money Vertex Pistons Top-End Piston Kits come with everything needed to replace your piston, top-end gaskets, and wrist pin bearing when the time comes. All Vertex 2-stroke pistons are gravity cast from an aluminum alloy with 18% silicon content. Because of a cast piston?s ability to contain higher silicon content compared to forged pistons, and because two-strokes have lower cylinder pressures when compared to four-strokes, cast pistons are ideal for two-stroke engines.

Details:

• All pistons are heat-treated with a T-5 hardening and tempering cycle
• Piston skirts are coated with a high-tech Molybdenum Disulphite coating for faster break-in time and increased piston life
• Gravity-cast aluminum alloy (not forged) with 18% silicone content, which produces an extremely light but very strong piston
• Silicone decreases thermal expansion, therefore can be run at tighter tolerances compared with forged pistons
• The high silicone content prolongs piston life by decreasing wear on the piston skirt, also making them less susceptible to rattling or breaking
• Replica pistons and all rings are OEM replacements
• Top end piston kits include piston, rings, wrist pin, circlips and top end gaskets (Includes head, base, intake and exhaust seals)

Kit includes:

• Piston with choosen bore
• Standard bore: 53.93 mm
• Piston rings
• Wrist pin with bearing
• Circlips
• Gaskets (head, base, intake and exhaust seals)
