Vertex Zuiger hc yamaha yzf 250 14-15

Vertex 4-takt zuigers:

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 profi les and compression ratios, offered in A, B, C and D sizes, to maximize power and performance while reducing blow-by and oil consumption.

Vertex Wrist Pin Features:

• KTM four-stroke wrist pins are DLC coated.

• 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 signifi cant 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.
