Vortex 170ZU-48 VTX Aluminum Rear Sprocket 48-Tooth

The Vortex 170ZU-48 is a 48-tooth aluminum rear sprocket engineered for motorcycle riders who demand precision, reduced rotating mass, and long-lasting drivetrain performance. Part of Vortex Racing's industry-renowned VTX aluminum sprocket lineup, this sprocket is a direct-fit, high-performance upgrade over heavier stock steel sprockets.

Key Features:

• Aerospace-Grade 7075 T6 Aluminum Construction — delivers an exceptional strength-to-weight ratio, significantly reducing rotating mass compared to OEM steel sprockets
• 100% CNC Machined — precision manufacturing ensures perfect concentricity on every unit, minimizing drivetrain vibration and extending chain life
• Patented Vortex Tooth Design — optimized tooth profile reduces chain drag and friction for smoother, more efficient acceleration and deceleration
• Clear Anodized Finish — bright silver appearance with a protective clear coat to resist oxidation and corrosion
• Lightening Holes — strategic cutouts further reduce rotating mass for improved throttle response and quicker acceleration
• 48-Tooth Rear Sprocket — provides tuned final drive gearing for enhanced low-end torque and acceleration
• Saber tooth grooves help keep the sprocket and chain free of debris

The Vortex 170ZU-48 is manufactured in the USA to the same exacting standards as the sprockets used on professional Superbike racing machines. It is available in single-tooth increments across the Vortex lineup, allowing precise gearing customization to match any riding style or track configuration.
