Product Details

The Vortex 313ZB-47 is a CAT5 series aluminum rear sprocket featuring a 47-tooth count and a satin black anodized finish. Engineered for motorcycle road racing, motocross, supercross, and street performance, this sprocket delivers a lightweight alternative to OEM steel units without sacrificing durability or precision.

Vortex CAT5 sprockets are machined from a lightweight aerospace-grade aluminum alloy formulated specifically to Vortex's proprietary specifications. Every sprocket is 100% CNC manufactured in the USA to tight tolerances, ensuring true concentricity for smooth, vibration-free chain engagement. The black anodized surface treatment resists corrosion and wear over extended service life.

Key Features:

  • 47-tooth rear sprocket for fine-tuned gear ratio adjustment
  • CAT5 series — lightweight aerospace-grade aluminum construction
  • Black anodized finish for corrosion resistance and appearance
  • Vortex patented tooth profile design for extended sprocket longevity
  • Saber tooth grooves for improved chain engagement and reduced wear
  • 100% CNC machined in the USA to precise tolerances
  • Compatible with 520-pitch chains (verify fitment for your application)

Vortex Racing has been manufacturing high-performance motorcycle drivetrain components for over 15 years, with products trusted by professional race teams worldwide. The 313ZB-47 is an ideal upgrade or direct replacement sprocket for riders looking to optimize gearing performance.

I ordered a tire from thmotorsports that the manufacturer had discontinued two years earlier and which I could not find anywhere else, without checking customer reviews first, something I never do. Had I checked reviews first I would never have placed the order as the reviews I read after placing my order were uniformly awful. But rather than call and cancel the order, which was my first impulse, I resisted the urge to do so and waited. A day later, the shipping update said my tire had shipped, so I waited. Another day later, the shipping update said my tire would arrive a day later by the end of the day so I waited. On the appointed day, the tire, exactly the tire I had ordered and which was unavailable anywhere else, arrived at the end of the day, brand new, in perfect condition and I was utterly amazed. Thank you, thmotorsports, I am so glad I did not look at your reviews before placing my order.

Thanks

Good to go

Shipping was lightning fast! Received order as described and in great condition. Expectations exceeded!

I found the engine compartment heater I needed for my 20' boat at the best price at Boatplicity. Fast, convenient and good price.
