Product Details

The Vortex 671ZR-57 is a high-performance aluminum rear sprocket featuring 57 teeth and a durable zinc-plated finish. Precision-machined from lightweight 7075-T6 aluminum alloy, this sprocket delivers significant weight savings compared to steel while maintaining excellent strength and durability for demanding riding conditions.

Key Features:

  • 57-tooth configuration for optimized gearing
  • Constructed from aerospace-grade 7075-T6 aluminum alloy
  • Zinc-plated finish provides superior corrosion resistance
  • CNC-machined for precise tolerances and perfect chain alignment
  • Self-cleaning mud grooves prevent debris buildup
  • Lightweight design reduces unsprung weight for improved handling
  • CAD-designed tooth profile ensures smooth power transfer and extended chain life

Vortex sprockets are engineered to meet or exceed OEM specifications and are a popular choice among street riders and racers seeking reliable performance upgrades. The aluminum construction offers approximately 66% weight reduction compared to steel sprockets while providing excellent wear characteristics.

So far so good

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.

Very smooth transaction, good email communication, order arrived as expected

Quick & Easy!

Love the price of tires

The product was in stock as advertised and received promptly; as compared to other that advertise but do have the item available at all.

I found good quality product more cheaper here. I installed the shocks. Did not have any problem.

So far so good

Awesome!
