Rear Steel Sprocket: 

JT sprockets are made using only the best available materials.SCM415 chromoly steel alloy for front sprockets, and we are the only sprocket manufacturer using the ultra-durable high carbon C49 steel for rear sprockets. The JT Sprockets factory is the largest and most advanced in the world. It is fully equipped with high accuracy machinery, including the latest generation of CNC computer design and computer controlled metal cutting equipment. The essence of a high quality sprocket is in the high precision of manufacturing and the inherent quality of the material. Through accurate machining, JT ensures maximum durability and performance. JT Sprockets are manufactured the right way – by hobbing, machining and drilling. This is the only proven way to achieve the closest of tolerances and the most accurate teeth profiles.

Heat treated and hand finished to perfection, all JT sprockets meet or exceed the highest possible quality standards set for the motorcycle industry.

Front Sprocket: 

Renthal off-road front chainwheels are chosen by more factory motocross and supercross teams than any other chainwheel on the market today.

They are CNC machined from a cased hardened and core refined 655M13 nickel chromium steel.

Most models utilize mud grooves which are CNC machined into each tooth on both sides to allow mud to flow away from the key contact points between the chain and the chainwheel. This helps reduce wear and increases the drivetrain lifespan.

Certain models are available in a computer aided Ultralight design to further reduce weight while still maintaining its structural integrity.

Chain:

D.I.D X-Ring reduces friction by twisting between the side plates instead of being squashed. Normal O-Rings and other makers’ modified O-Rings have squashed points that increase friction. The twisting resilience of the X-Ring’s four sections greatly increases its sealing performance. This keeps the dirt out and the lubrication in much better than any other O-Ring. X-Rings have the greatest wear resistance of any other type of O-Ring or Non-O-Ring chain
