Vortex 435V4-48 VTX 520-Pitch 48-Tooth Aluminum Rear Sprocket

The Vortex 435V4-48 is a 520-pitch, 48-tooth aluminum rear sprocket designed as a lightweight, high-performance upgrade over a heavy OEM steel sprocket. CNC-machined in the USA from aerospace-grade 7075-T6 aluminum, this sprocket delivers an exceptional strength-to-weight ratio trusted by racers and street riders alike.

Reducing rotating mass at the rear wheel has a multiplied effect on performance — less rotating weight means faster acceleration and more responsive throttle feel. The Vortex patented tooth profile is engineered to minimize drag and friction, extending the service life of both the sprocket and chain.

Key Features:

• 520 Chain Pitch — fits OEM 520 applications and suitable 520 conversion setups
• 48 Teeth — for fine-tuned final drive ratio adjustment
• 7075-T6 aerospace aluminum construction for maximum strength and minimum weight
• 100% CNC machined in the USA to the tightest tolerances for perfect concentricity every time
• Patented Vortex tooth design reduces friction and drag for improved acceleration and deceleration
• CAT5 anodized finish (V4 color variant) with electrically coated surface for a bright, corrosion-resistant shine
• Saber tooth grooves and lightening holes reduce rotating mass and keep components clean
• Available in single-tooth increments for precise gearing customization

The Vortex 435V4-48 rear sprocket is an ideal choice for riders looking to optimize gearing, reduce drivetrain weight, and add a distinctive anodized look to their motorcycle's final drive system.
