• 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 sandblasted to lower material surface tension
• Meet or exceed the highest-quality compound standards set by the motorcycle industry

NOTES:

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

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).

For Suzuki DR370 1978-79 and SP370 1978-1979, standard chain length is 100

(1) 16T. Front steel sprocket for 520 chain
