The JT Sprockets Difference

  1. Constructed using only the best materials. JT sprockets are made using only the best available materials. Japanese SCM420 chromoly steel alloy for front sprockets, and we are the only sprocket manufacturer in the world today using the ultra-durable high carbon C49 steel for rear sprockets. For MX and street lightweight competition sprockets we use Austrian made Aviation–grade 7075-T6 aluminium alloy .
  2. Made the right way. 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.
  3. Quality Control. Every sprocket goes through up to 25 production stages and 10 individual quality control checks before it is ready to leave the factory and the production facility has achieved the highest European quality standards.
  4. Leading distributor network. With an international network of leading distributors in over 70 countries worldwide, it is always possible to find a local official JT Sprockets supplier.
  5. Range and Availability. We produce and stock, the widest range of sprockets for all motorcycle brands covering models from early Sixties to today. Our range also includes sprockets for alternative gearing and alternative chain sizes. Comprehensive stocks are always kept at the JT Sprockets distribution centres in Kent UK and Atlanta USA, ready for immediate delivery. With more than a million sprockets in stock at any given time, supply is never a problem.

All aluminium MX rear racing sprockets are manufactured from the best materials with a special self-cleaning design, and hand-finished to perfection.
  4. OEM Type Rubber Cushioned Front Sprockets.Rubber cushioned sprockets have been widely used by the major Japanese motorcycle manufacturers since early 1990’s to dampen the chain impact on the teeth of the front sprocket. JT Sprockets has now released these same sprockets to the after market. Quality, design and OEM proven technology are the same as used for what is supplied to the motorcycle manufacturers and genuine replacement parts.
