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.
