JT Sprockets for Motorcycles

JT holds the distinction of being a global leader in aftermarket sprockets for motorcycles and ATVs. They manufacture more of these parts than all the competitors combined, holding a 60-percent share of the business. To tell the story in numbers, this London-based company has the annual production rate of more than 18 million sprockets. The secret behind those massive sales is the quality of each and every component. It comes from using the most durable raw materials, ensuring precise tolerances, and implementing multi-stage quality assurance.

JT sprockets are constructed of the finest grades of steel and aluminum. It is the only brand to use C49 high carbon steel for its sprockets. This super-hard material goes into the production of JT rear sprockets, while the front ones are made from SCM420 chromoly steel alloy and are fully heat treated instead of being surface hardened. This kind of treatment ensures way higher durability of the product through superior structural integrity. That’s because when the upper layer of a surface hardened sprocket wears down, it reveals softer, less durable metal. You don’t want that for your bike, especially if you push it to the limit. High-quality material construction translates into the lasting service life of not only the sprocket itself but the chain as well.

Lightweight racing sprockets by JT are made from 7075-T6 aluminum alloy, which is the highest-grade aluminum currently on offer. This very material used in the manufacture of the Airbus airplanes. All of the company’s aluminum MX rear sprockets feature self-cleaning constructions, which is something that other aftermarket manufacturers offer as an option. Choosing the proper material is only part of the story as the quality of a sprocket also depends on how well it is machined. Each and every one of the JT sprockets is CNC designed & cut, hobbed, machined, and drilled – that’s how the closest tolerances are achieved. Before reaching the end user, all sprockets undergo as many as ten different QA procedures.

The expertise that goes into JT sprockets makes them the number one choice of motorcyclists around the world. You’ll also find them in the majority of chain and sprocket kits by renowned chain manufacturers. However, JT offers proprietary drive chains as well. The company also makes performance brake rotors for MX and dirt bikes. Off-road racing conditions place high demands on brake disks due to considerable heat and wet & muddy environments. To prevent overheating, JT brake rotors feature a stripped outer profile. Self-cleaning holes further improve heat dissipation, while also driving out mud and debris and reducing the overall weight of the disc. These rotors are constructed of heat-treated stainless steel and are compatible with any brake pads out there.
