JT SPROCKETS Standard Steel Sprocket 1078 - 420 (Ref. JTR1078.47)
Designed to replace the original part or modify the gearing, this JT Sprockets sprocket provides a reliable solution for the transmission of small urban cylinders. Machined from C49 carbon steel, it features a sleek black finish that discreetly integrates into the drivetrain.
Material: steel (C49 carbon)
Color: black
Number of teeth: 47
Chain pitch: 420
Type: standard
Suitable for daily use in urban environments — short trips, frequent starts, and riding in heavy traffic — this sprocket is designed for compatible 420 transmissions. It is a wear part designed to work with a matching pinion and chain to ensure proper engagement of the links and limit premature wear.
Examples of compatible motorcycles: YAMAHA TZR 50 (2011-2012), MBK X-POWER (2012) — always check the manufacturer reference and chain pitch before installation.
Replace your sprocket with a JT Sprockets part to restore the original transmission geometry and get back on the road with confidence.
