JT SPROCKETS Standard Steel Sprocket 1134 - 428 (Manufacturer's reference: JTR1134.48)
Designed for replacement or gearing changes, this JT Sprockets sprocket is aimed at riders who demand reliability from their transmission. Machined from C49 carbon steel, it features a sleek black finish that fits all 428 transmissions. As a standard part, it allows for direct reassembly without modification for secondary drives designed for 428.
Suitable for urban use, roadsters, or light off-road (cross), this JT sprocket is a versatile choice for restoring the original transmission geometry or modifying the gearing. It is particularly compatible with 125 cc models such as the RIEJU TANGO 125I SCRAMBLER (2020), the MOTOR HISPANIA MH10 PRO SM (2013), and the DERBI TERRA 125 ADVENTURE (2013), subject to verification of the bolt pattern and number of fixings.
Replace your sprocket while respecting the torque specifications and chain/sprocket alignment to ensure the longevity of the assembly. Manufacturer reference: JTR1134.48.
