The Vortex 312DZB-45 is a high-performance 45-tooth rear sprocket engineered for smaller displacement motorcycles and minibikes using 415-pitch chain. This lightweight aluminum sprocket is precision CNC machined from 7075-T6 billet aluminum to exact tolerances, delivering exceptional strength while reducing rotational mass for improved acceleration and throttle response.

Key Features:

• 45-tooth count for 415-pitch chain applications
• 7075-T6 billet aluminum construction for superior strength-to-weight ratio
• PTFE black hardcoat finish bonds to aluminum for enhanced durability and reduced friction
• Saber tooth groove design increases sprocket longevity
• 100% CNC machined to precise tolerances ensuring concentricity
• Vortex patent pending tooth design trusted by professional race teams
• Manufactured in the USA by Vortex Racing

Vortex sprockets are track-tested by top professional teams and designed for riders who demand race-proven performance and reliability. The specialized hardcoat treatment creates a more durable surface that resists wear while the precision machining ensures smooth, consistent power transfer.
