Product Details

The Vortex 253ZB-51 is a CAT5 series black steel rear sprocket featuring a 51-tooth count, engineered for motorcycle applications requiring reliable and durable chain drive performance. Manufactured in the USA by Vortex Racing, this sprocket is built to the same exacting standards trusted by professional racing teams worldwide.

Key Features:

  • 51-Tooth Rear Sprocket — delivers a lower overall gear ratio for improved low-end torque and acceleration
  • Black Steel Construction — carbon steel alloy formulated to Vortex specifications for superior strength and wear resistance
  • Electroplated Satin Black Finish — corrosion-resistant coating for extended service life in all conditions
  • Vortex Patented Tooth Design — unique tooth geometry increases sprocket longevity and promotes smooth chain engagement
  • CNC Precision Manufactured — machined to tight tolerances ensuring concentricity and quiet, vibration-free operation
  • Hardened Teeth — induction-hardened for increased durability under hard acceleration and racing conditions
  • Drilled Lightening Holes — strategically placed holes reduce rotating mass without compromising structural integrity

Vortex Racing has been a trusted name in motorcycle powersports components for over 15 years, supplying sprockets and drivetrain parts to motocross, road racing, supercross, flat track, and minibike disciplines. The 253ZB-51 is a direct-fit replacement or performance upgrade sprocket, offering the dependability and precision that Vortex is known for on both the street and the track.

shopping was fast and easy

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.
