JT SPROCKETS Standard Steel Sprocket 838 - 428 (Ref. JTR838.49)

Replace your worn part with a sprocket designed for daily road use. This JT Sprockets sprocket, intended for urban and roadster environments, is machined from C49 carbon steel for mechanical strength suited to transmission stresses. With its 49 teeth and 428 chain pitch, it allows for adjustment or maintenance of the original gearing while keeping acceleration and engine braking behavior predictable.

• Material: steel (C49 carbon)
• Number of teeth: 49
• Chain pitch: 428
• Type: standard, sprocket reference 838

Designed for easy installation during a transmission overhaul, this sprocket is aimed at small displacement bikes and roadsters (e.g., Yamaha YBR 125, SYM XS 125K). It fits perfectly into a classic drivetrain made up of a 428 chain and a matching sprocket. Ideal for riders seeking durability and consistent drive without radical changes in handling.
