Overview of JT Sprocket - JTR818.40

  • Maximum strength sprockets at minimum weight; front sprockets made with C45 steel and SCM415 chromoly steel alloy -- rear sprockets made with C45 high carbon steel
  • Each sprocket is heat-treated and finished by hand
  • Each sprocket is sandblasted to reduce surface tension and anodized to a beautiful satin-silk finish
  • Meniscus-shaped self-cleaning grooves featured on both sides of teeth
  • Meet or exceed the highest-quality compound mod. standards set by the motorcycle industry

NOTE: At this time we are not able to specify on our website the standard tooth sizes of the sprockets or size and length of chain for your motorcycle. We will display every sprocket that fits. If you need the standard tooth size information or chain size and length, call us toll-free 800-969-7504

NOTE: Anytime you use other than the standard front/rear sprocket sizes, clearance must be checked. When converting to a smaller chain size, especially for racing, be sure to use the highest-grade O-ring chain available (heavy-duty non-O-ring acceptable for drag racing)
