Vortex 170ZR-49 VTX Aluminum Rear Sprocket 49-Tooth

The Vortex 170ZR-49 is a 49-tooth aluminum rear sprocket engineered for motorcycle road racing and high-performance street riding. Machined 100% in the USA from 7075 T6 aircraft-grade aluminum, this sprocket delivers an ideal balance of lightweight construction and proven durability.

Vortex's iconic CAT5 CNC-machined design features a two-tone anodized finish applied before the sprocket teeth are cut, resulting in the signature machined look Vortex is known for.
