Vortex 436ZKV4-43 VTX Aluminum Rear Sprocket Sprockets - 43-Tooth 530-Pitch Black

The Vortex 436ZKV4-43 is a 43-tooth, 530-pitch aluminum rear sprocket engineered for performance motorcycle applications. CNC-machined from 7075-T6 aerospace-grade billet aluminum, this sprocket delivers an exceptional strength-to-weight ratio, reducing rotating mass for improved throttle response, acceleration, and deceleration feel.

This sprocket features Vortex's black hardcoat PTFE (polytetrafluoroethylene) finish, which bonds directly to the aluminum surface to create a harder, more wear-resistant coating with reduced friction compared to standard anodized finishes. The unique tooth profile and patented Vortex design help extend sprocket longevity under demanding riding conditions.
