Description

Manufactured in Italy, Vertex offers state of the art quality pistons.
Manufactured to the highest standards in Japan, Vertex piston rings are direct OEM replacements.
All Vertex piston kits include the piston, rings, wrist pin and circlips; and every Vertex piston has a Molybdenum Disulphide coating on the piston skirt.
Vertex 2-stroke pistons are cast aluminum with 18% silicon content. This decreases thermal expansion, creates better power and decreases wear.
4-stroke pistons are forged from the highest quality aluminum alloy for superior strength and durability.
