VERTEX TOP END ENGINE REBUILD KIT

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 (for two-strokes) when the time comes. Included are the piston, rings, wrist pin, circlips, top end gaskets, and even wrist pin bearing (for two-stroke applications). Four-stroke kits include a free Camchain!

VERTEX Piston Features

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. Vertex offers enthusiasts state-of-the-art, high-quality pistons for nearly any powersport use from motorcycles and ATVs to marine and karting. Manufactured to the highest standards in Japan, Vertex’s piston rings are produced by the OEM suppliers so that they are direct OEM replacements. Vertex is the choice of those who truly seek the optimum in powersport performance in any application.

VERTEX Wrist Pin Features

Case hardened wrist pins are used with all Vertex pistons.Nitride coated pins are normally used for high performance four-stroke engines utilizing a bronze bushing or with engines using a steel connecting rod without bearings. This hardened surface is highly wear resistant and provides anti-galling properties. Nitriding is a highly specialized surface treatment that produces a highly wear resistant surface. The significant advantage of nitriding is that the surface hardness is developed without quenching and the attendant distortion problems with case hardening. Finishing operations can be eliminated or held to a minimum.

Crafted from military-spec certified TI3Al titanium alloy, Vertex Titanium Valves are made to endure the harshest racing conditions. Forged from a single blank, grain flow is improved to enhance the mechanical characteristics of the valve without having to resort to welding. Special PVD, CVD, and CrN coatings are used to provide low-friction surfaces that reduce heat generation and resist carbon build-up; coatings allow alloys like titanium to become ultra-smooth while reaching hardness levels 5x that of high-speed steel.
