STREET SPROCKET CONVERSIONS

Renthal logo

Features

  • Sprockets allow you to convert your 91-99 Sportster from belt to 520 chain drive
  • Chain drive allows use of a wider rear tire
  • Renthal countershaft sprockets are CNC-machined, not stamped, and are case-hardened and core-refined for the highest quality – these are the most perfectly concentric sprockets you can buy
  • Countershaft sprockets are made from nickel-chromoly steel
  • Rear sprockets are constructed of 7075 T-6 aluminum for lighter weight and hard-anodized for added wear resistance
  • Rear sprockets also feature a special tooth profile that allows the chain to roll easily on and off the sprocket for longer wear, less noise and more power
  • Sprockets are sold each; must order one front and one rear sprocket for chain-drive conversion
  • Drive chain sold separately
