Complete trasmission kit PBR EK Z42-15 with chain 520. rear steel sproket from 42 and front sproket from 15 for KTM 690 SMC R 19 -- 23

The motorcycles transmission in general is the set of components that have the purpose of transferring the power generated from engine to wheel. It is a mechanical system subjected to great stress and wear, for this reason it is advisable to replace it at intervals of approx 20.000 Km. or when visually the components are ruined due to poor maintenance.
In the production of transmission gears: chains, front and rear sprocket, PBR is a leader in the industry at international level. The components are totally produced in Italy. Competence, reliability and durability have made the PBR products among the most popular in the motorcycle industry, private and sporty. Years of research into techniques and materials, the work of skilled craftsmen and the use of industrial technologies for CNC machining bring the PBR components to an exclusive level. The roller chain transmission (The most used in motorcycle) includes 3 main components: Roller chain: is composed by short cylindrical rollers held together by side links: This system gives freedom of movement allowing to turn around to the rear and front sprocket teeth attenuating friction. Made of durable material but at the same time flexible for optimum performance. Transmission kits include the renowned Enuma Chain chains, strictly Made in Japan, the world's largest chain manufacturer, the holder of the most important patents. Various types of EK chains (normal, high sliding, O-Ring, X-Ring) are supplied in the kit, depending on the type of engine, and accordingly the power and torque of the motor the choice of the most suitable one, and in most cases, transmissions are better than the standard ones. Rear sprocket: It is the largest toothed wheel easily identifiable on the rear wheel of motorcycle, it's the rear sprocket to transmit movement. It consists of a variable tooth depending on brand and model of the bike. Made of steel (stronger but heavier) or Alu (lighter but more consumable). Front sprocket: Product Component Steel, is the smallest toothed wheel, usually not visible because it is covered by a specific cover, is connected to the gearshift shaft, turning in contact with the gears in this way the roller chain is activated and It transfers the movement to the rear sprocket moving the bike. Also the front sprocket like the rear sprocket has a variable depending on the model and the brand of the bike
