JT Sprockets Standard Steel Sprocket 15 - 525 (43 Teeth)
Designed for 525 chain transmissions, this JT SPROCKETS part number JTR15.43 is a reliable replacement part for roadsters. Made from quality steel (carbon C49), it offers the expected mechanical strength for daily road use and urban trajectories as well as Sunday rides.
Changing the sprocket allows for adjustment of the gearing: a larger sprocket favours acceleration, while a smaller one prioritises top speed. This 43-tooth sprocket is aimed at riders looking to maintain a versatile compromise between responsiveness and speed. Easy to install by a mechanic or in a personal workshop, it fits with homologated 525 chain-sprocket kits.
Examples of common compatibility: BENELLI LEONCINO 800 (2025), BENELLI TRK 502 (2025), BENELLI LEONCINO 500 (2024). Always check the original part number and pitch before installation.
