Product Details

The Vortex 254ZR-51 is a 51-tooth, 520-pitch CAT5 aluminum rear sprocket built for riders who demand race-proven performance on the street or track. Manufactured in the USA, this sprocket is 100% CNC machined from aerospace-grade 7075 T6 aluminum, delivering an optimal balance of lightweight construction and exceptional durability.

Key Features:

  • CAT5 Anodized Finish: Color anodized before CNC machining to produce the iconic two-tone silver-accent look with added corrosion protection
  • 7075 T6 Aluminum Construction: Aerospace-grade alloy provides maximum strength at roughly half the weight of a steel sprocket
  • Lightening Holes: Strategically placed cutouts reduce rotating mass for improved throttle response and acceleration
  • Precision CNC Machined: Manufactured to tight tolerances for a perfectly concentric sprocket and smooth, quiet power delivery
  • Gunk-Clearing Tooth Grooves: Built-in grooves between teeth help shed debris and keep the drivetrain running cleanly
  • 520 Chain Pitch: Compatible with standard 520-pitch chain applications
  • 51 Teeth: Higher tooth count for tuned low-end torque and acceleration

Maintenance Note: Aluminum sprockets perform best when the chain is cleaned and properly tensioned every 300–600 miles on street bikes to maximize sprocket and chain life.

Vortex Racing has been a trusted supplier to professional racing teams across multiple motorsport disciplines. The 254ZR-51 reflects the same commitment to precision manufacturing and performance engineering that has made Vortex the go-to sprocket brand for serious riders.

Transaction was smooth, shipped quickly

I never received anything about shipping so I contacted customer support. They said it was a direct shipment and they would check on it for me and get back to me. I never heard back from them. Shortly after that I did receive a message from the carrier saying they have my shipment and scheduled a delivery. They said they would call me 30 mins before the delivery so I could get off work and come to inspect it before signing for it. That didnt' happen either my wife called me first thing in the morning and say they are here delivering it now so I had to run home so I could inspect it. The driver was really nice and waited for me to get there.

Thank you

You guys got me the part very fast. Thanks

The item I bought was one to replace something I thought I had accidentally thrown away. A couple days after the boatplicity item arrived I located the like item I already had. I initiated the return process with boatplicity, as I no longer had need of the item. I completed the return request stuff and it said I would be contacted to continue the process but no one has contacted me.

I'm waiting on my refund. I was not happy that I couldn't talk to a real person regarding my return and my repurchase of the correct prop that I needed. So , if I get my total refund without a huge restocking fee(since the prop is new in original packaging and I bought another prop that is the correct size) then I will be extremely satisfied.

The ordering process was simple and the tire was shipped quickly. My overall experience was great and I would order from Motorsport.com again!

It was fast easy going .
