Vortex 720-45 Aluminum Rear Sprocket 45-Tooth

The Vortex 720-45 is a 45-tooth aluminum rear sprocket engineered for high-performance motorcycle applications. Built to Vortex Racing's exacting standards, this sprocket is 100% CNC machined in the USA from aerospace-grade aluminum, delivering an ideal balance of strength and reduced rotating mass for improved throttle response and power transfer.

Key Features:

• 45-Tooth Rear Sprocket — allows riders to fine-tune gear ratios for improved low-end acceleration and torque
• Aerospace-Grade Aluminum Construction — significantly lighter than steel counterparts, reducing rotational mass and increasing rear-wheel power output
• 100% CNC Manufactured in the USA — precision machined for consistent tooth profile and reliable chain engagement
• Anodized Finish — protective coating helps resist oxidation and extends service life
• Iconic Two-Tone Machined Look — finish applied before cutting reveals the signature Vortex machined appearance

Vortex Racing rear sprockets are a popular choice for street riders and racers looking to replace OEM gearing or optimize their motorcycle's performance characteristics. Proper chain tension and cleanliness should be maintained to maximize sprocket life, particularly with aluminum sprockets.
