JT Sprockets
World's No. 1 Aftermarket Sprocket Manufacturer
The JT motorcycle sprockets' factory is today 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. JT is producing
a full range of sprockets for the aftermarket as well as for the OEM.
The essence of a high quality sprocket is in the high precision of manufacturing
and the inherent quality of the material. Through accurate machining and by using
only the best grade of C45 High Carbon steel for rear sprockets and SCM415 Chromoly
steel alloy for front sprockets, JT ensures Maximum Durability performance for both
Drive chain and sprockets.
JT manufactures sprockets the right way, by hobbing, machining and drilling. This
is the only proven way to achieve the closest of tolerances and the best 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. Each sprocket
goes through up to 25 production stages and 10 individual quality controls checks
before it is ready to leave the factory.
JT designs and produces 12 million sprockets a year for all makes and models of
motorcycles. The current range is over 2500 types of steel or 7075T6 aluminium alloy
and many items combine two or more different fittings into one sprocket.
D.I.D SUPER HEAVY DUTY X-RING® ZVM-X
D.I.D’S ZVM-X-RING® IS THE FORMULA FOR MAXIMUM LONG LIFE IN X-RING® TECHNOLOGY
D.I.D has redesigned the shape of the X-Ring® to maximize wear resistance of the
new 530ZVM-X and 525ZVM-X chains. These two models have also been beefed up in tensile
strength to make them the ultimate chains for today's high performance sport and
sport touring motorcycles. The new ZVM-X-RING retains all the low friction, high
performance characteristics of the standard X-Ring® while providing a significant
increase in wear resistance and overall life of the chain.

D.I.D HEAVY DUTY X-RING
D.I.D’S patented X-Ring® construction 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 action of the
X-Ring® disperses the pressure and minimizes power loss.
The X-Ring's four contact points greatly increase its sealing performance. This
keeps the dirt out and the lubrication in much better than any other O-Ring. The
D.I.D X-Ring® has the greatest wear resistance of any other type of O-Ring or non
O-Ring chain.

D.I.D CHAIN IS THE CHAMPION FOR SUPERCROSS AND MOTOCROSS
- D.I.D ER chain is designed exclusively for racingctory Supercross and Motocross
Teams
- 520MX chain has higher tensile strength for maximum performance and is ideal for
muddy/sandy conditions
- D.I.D's exclusive SDH pin treatment is the secret behind the superior performance
of our 520ERT2, 520MX and all NZ series chains
- SDH hi-tech pin treatment forms an extremely hard chromium carbide layer on the
pins surface while maintaining a soft inner core
- SDH treated pins have extreme impact strength while maintaining outstanding shock
absorption
- SDH creates a chain with superior wear resistance, antioxidation properties and
performs well against invasion of hard foreign materials
UNIBEAR High Quality Chains
Uni-Bear chain has been manufactured to a high standard using specialised C.N.C.
chain production equipment. The outer links and bushes have been polished to give
smooth running with reduced friction. Each part of the chain has been hardened for
maximum wear resistance and then final anti corrosion material has been applied
to all surfaces. The lubricating film on the surface of the chain will provide excellent
first time wear resistance.
