JT DRIVE CHAIN 520X1R3 14/42 chain kit, designed for roadsters seeking a robust and precise transmission. This kit combines a chain with a pitch of 520 of type X1R3 equipped with XS-Ring seals and a steel sprocket in standard mounting (sprocket ratio 14 / sprocket 42). Black/steel finish for a sleek and durable look on the chain table.

• Type: Complete chain kit (chain 520 X1R3 + standard steel sprocket)

Suitable for roadsters such as the Kawasaki Z 300 (2016–2018 versions), this kit replaces the original transmission without modification of the standard mounting.

This JT kit is aimed at riders looking for a racing type chain with a refined finish and standard steel components, for a restoration or replacement during routine maintenance.
