JT Drive Chain "paphes" with HPO O' Ring Chain and JT sprockets for HONDA SUPRA 100 1999-2003.
JT sprockets are manufactured from top-quality steel, with the rear sprockets made from C45 hardness steel using heat induction, and from SCM (chromium molybdenum) steel alloy with full hardening for the front sprockets.
The black color on the rear adds extra mileage "durability" (ZINC coating).
