Manufacturer Ref: JTR24.51
The JT Sprockets JTR24.51 standard steel sprocket is designed for urban transmissions equipped with a 420 pitch chain. Machined from C49 carbon steel, it features a 51-tooth design and a sleek black finish, suitable for 50cc engines and both road and city use.
Designed for standard sprocket replacement, it is easy to install during transmission maintenance (sprocket-sprocket-chain replacement). Its material and machining are chosen to ensure good mechanical resistance and controlled wear under normal usage conditions. Ideal for restoring a healthy tooth profile after wear on the old sprocket or for slightly modifying the gearing while remaining on 420 equipment.
