Vortex 312D-54 Aluminum Rear Sprocket 415 Pitch 54-Tooth

The Vortex 312D-54 is a 54-tooth, 415-pitch aluminum rear sprocket designed for competitive motorcycle racing applications. CNC machined in the USA from 7075 aircraft-grade aluminum, this sprocket delivers an exceptional strength-to-weight ratio and has become an industry benchmark for lightweight, high-strength drivetrain components.

Key Features:

• 54-Tooth / 415 Pitch — optimized tooth count for corner-exit drive and acceleration on most track configurations
• 7075 Aircraft-Grade Aluminum Construction — delivers superior strength while dramatically reducing rotating unsprung mass compared to steel sprockets
• 100% CNC Machined in the USA — precision manufacturing ensures perfect concentricity and consistent fit
• Lightening Holes — strategically placed to further reduce weight without compromising structural integrity
• Anodized Finish — hard anodized surface for improved wear resistance and corrosion protection
• Race-Proven Design — trusted by professional and club racers at all levels of competition

The 312D series is engineered to precise specifications for concentricity and durability, making it a direct performance upgrade over OEM sprockets. The 54-tooth rear sprocket is a popular choice for riders seeking stronger corner-exit acceleration and improved low-to-mid range drive on technical track layouts.
