Vortex 316ZO-50 CAT5 Aluminum Rear Sprocket 520 Pitch 50 Tooth Orange

The Vortex 316ZO-50 is a CAT5 aluminum rear sprocket featuring a 520 pitch and 50-tooth count in a striking orange anodized finish. Precision-engineered for performance street and track riders, this sprocket is a significant upgrade over heavy OEM steel units, delivering reduced rotational weight and improved throttle response.

Manufactured entirely in the USA, Vortex uses a specially formulated aluminum alloy machined to exacting tolerances on CNC equipment. The color anodizing is applied to the body of the sprocket while excluding the sweeps, mud grooves, and teeth, resulting in a vivid orange face with contrasting bright silver machine-cut highlights for a premium race-ready appearance.
