Details

    Renthal Ultralight Rear Sprockets start their lives off by getting CNC machined from 7075 T-6 aluminum, an alloy that is prized for its strength and wear resistance. A near perfect material for sprockets. The alloy is light weight, and with Renthal’s drilled patterns, the Ultralight weighs up to 66 percent less than comparable steel sprockets while retaining a comparable lifespan. The material isn’t the only thing that promotes longevity. Self-cleaning cuts are machined into each chain groove to clear away mud and debris from sensitive wearing surfaces, so both the sprocket and chain are kept clean of abrasive particles. There’s almost no downside to putting a Renthal Rear Sprocket on your motorcycle or ATV.

    Specs:
  • Replacement aluminum rear drive sprocket
  • 66% lighter than comparable steel sprockets
  • Comparable lifespan to much heavier sprockets
  • 7075 T-6 aluminum alloy
  • Self-cleaning chain grooves
  • Fits OEM bolt mounts
  • Multiple colors available

wore way too fast

Comments On Sep 22, 2015:i bought black to make the bike look good. this sprocket didn't wear like i expected it too. the other guys i ride with do not ready care to use them either. they had the same issue. i thought chain adjusting was the issue but we all take care of our bike for peak performance. saving weight, what weight on a 450cc dirt bike, my if your loosing races because of your back sprocket having a few extra ounces maybe you should stop racing.
