989 PISTON KITS Vertex Piston Kit 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. Cast vs Forged. What’s better and why? Vertex Two-stroke Pistons 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 fourstrokes, cast pistons are ideal for two-stroke engines. Vertex pistons are gravity cast from an aluminum alloy with 18% silicon content. Silicon is important because: • It decreases thermal expansion, which changes the geometry after the piston reaches operating temperature. With low thermal expansion characteristics, Vertex pistons can be run at tighter tolerances compared with forged pistons. This creates better power and performance, also making them less susceptible to rattling or breaking. • Silicon gives the pistons better wear characteristics and prolongs piston life by decreasing wear on the piston skirt. Vertex Four-stroke Pistons Four-stroke engines have much higher cylinder pressures when compared to two strokes and are generally manufactured from forgings. To handle the internal pressures of a four-stroke engine, Vertex’s four-stroke pistons are forged from the highest quality 2618 aluminum alloy for superior strength and durability. Vertex uses unique piston profiles and compression ratios, offered in A, B, C and D sizes, to maximize power and performance while reducing blow-by and oil consumption. All Vertex Pistons Feature: • Standard pistons and components are OEM replacements. • Kits include piston, rings, wrist pin and circlips. • All pistons are heat treated with a T-5 or T-6 hardening and tempering cycle. • Replacement rings are sold individually.

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. Vertex Piston Rings Vertex’s latest generation two-stroke and four-stroke piston rings are nitride coated or chrome plated, increasing wear resistance and extending durability. Vertex piston rings are exact OEM replacements. CC Model Year Version Comp. Ratio Cylinder Bore (mm) Piston Diam.
