Features

JT SPROCKETS standard steel sprocket 1844 - 428 (manufacturer reference: JTR1844.48) is a transmission sprocket designed for roadsters and 125cc motorcycles equipped with a 428 pitch chain. Made from C49 steel, it offers robust construction suited to the demands of transmission, for either a direct replacement or a gearing adjustment.

Material: C49 Steel (black)
Number of teeth: 48
Chain pitch: 428
Type: Standard

The JTR1844.48 sprocket installs easily in place of the original part on compatible transmissions. Its carbon steel design is intended to withstand wear from road use and torque stresses, while also facilitating regular maintenance (checking tension and lubricating the chain).

YAMAHA MT-125 (2025 - 125 cc)
