Product Details

The Vortex 144AV4-42 is a 42-tooth aluminum rear sprocket engineered for riders who demand lightweight performance without sacrificing durability. Designed for 525-pitch chain applications, this sprocket is CNC-machined from 7075-T6 billet aluminum — an aerospace-grade alloy that delivers an exceptional strength-to-weight ratio and reduces overall rotating mass for improved throttle response.

Key Features:

  • 7075-T6 billet aluminum construction — lightweight yet exceptionally strong aerospace-grade material
  • 42 teeth / 525 chain pitch — engineered for precise chain engagement and efficient power transfer
  • CNC machined to tight tolerances for consistent fit and smooth operation
  • Anodized finish for corrosion resistance and long-lasting appearance
  • Vortex patent-pending saber tooth groove design for reduced friction and improved chain wear
  • Reduces rotating mass for improved acceleration, deceleration, and directional changes
  • Made in the USA by a trusted name in motorcycle racing

Vortex Racing has been manufacturing top-quality motorcycle drivetrain components for over 15 years, with products proven in Motocross, Supercross, Road Racing, and Flat Track competition. The 144AV4-42 rear sprocket is a direct-fit, high-performance upgrade over stock steel sprockets, offering significant weight savings for street, track, and competition use.

Lovely experience would definitely buy again

Excellent price and excellent service. Unit arrived ahead of schedule. Much appreciated the excellent service.

Shipping was fast and received tires in a couple of days. Great prices also.

Had the tires I wanted at a fair price and delivered quickly! Thank you!

Delivery was later than expected

It's the information I needed for my boat motor. The only issue I had with this maintenance manual was the way the manual was finished. I've worked the the graphic arts industry for 50 years and am well versed in print finishing. The book will no doubt stay together, however there is excessive glue on the spine as the cover wraps around the front/back that distracts from the overall appearance.

Great prices and super fast check out thanks

Great response time for email enquiry
