EK/PBR 525H 14/42 Chain Kit - Standard Sprocket by EK CHAIN: a transmission kit designed for roadsters looking for a reliable and economical set. This kit includes a chain with a pitch of 525 and a standard steel sprocket (42 teeth) paired with a 14-tooth pinion, ready to be installed to restore the secondary transmission of your machine.
Designed for road use, this chain kit is aimed at riders who perform regular maintenance: lubrication, tensioning, and link inspection. Ideal for replacing a worn transmission set on roadsters such as the BENELLI TRK 502 (2023–2025), it offers simple installation and classic compatibility thanks to the 525H standard. Be sure to check tension settings and alignment during installation to ensure smooth and secure transmission.
