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 Piston type Vertex Two-stroke Pistons Replica: cast OE replica Because of a cast piston’s ability to contain higher silicon content compared to forged Race: unique cast GP style with only one compression ring pistons, and because two-strokes have lower cylinder pressures when compared to four- Pro: forged replacement for a OE cast piston for better strength strokes, cast pistons are ideal for two-stroke engines. Vertex pistons are gravity cast from Replica BB: big bore stock compression cast piston an aluminum alloy with 18% silicon content. Pro Replica: forged OE stock compression piston Pro BB: forged OE stock compression big bore piston Silicon is important because: Pro Race: unique forged GP style race piston with only one compression ring • It decreases thermal expansion, which changes the geometry after the piston reaches Pro HC: forged high compression pistons operating temperature. With low thermal expansion characteristics, Vertex pistons can be run at tighter tolerances compared with forged pistons. This creates better power Vertex Wrist Pin Features: and performance, also making them less susceptible to rattling or breaking. • KTM four-stroke wrist pins are DLC coated. • Silicon gives the pistons better wear characteristics and prolongs piston life by • Case hardened wrist pins are used with all Vertex pistons. decreasing wear on the piston skirt. • Nitride coated pins are normally used for high performance four-stroke engines utilizing a bronze bushing or with engines using a steel connecting Vertex Four-stroke Pistons rod without bearings. This hardened surface is highly wear resistant and Four-stroke engines have much higher cylinder pressures when compared to two strokes provides anti-galling properties. and are generally manufactured from forgings. To handle the internal pressures of a •Nitriding is a highly specialized surface treatment that produces a highly wear four-stroke engine, Vertex’s four-stroke pistons are forged from the highest quality 2618 resistant surface. The significant advantage of nitriding is that the surface aluminum alloy for superior strength and durability. Vertex uses unique piston profiles and hardness is developed without quenching and the attendant distortion problems compression ratios, offered in A, B, C and D sizes, to maximize power and performance with case hardening. Finishing operations can be eliminated or held to a minimum. while reducing blow-by and oil consumption.
