Features

EK CHAIN 420SR 11/53 Chain Kit - Standard Sprocket

This complete kit includes the EK 420SR non O-ring chain, a PBR steel front sprocket, and a steel rear sprocket: a simple and robust solution for the transmission of small displacement motorcycles, particularly suited for urban use and light road outings. Designed to replace the entire sprocket/chain/sprocket set at once, it simplifies maintenance and restores precision to the transmission.

Kit contents:

EK 420SR chain (surface treatment for lubrication and protection)
PBR steel front sprocket
Steel rear sprocket (standard sprocket)

Technical specifications:

Pitch: 420
Configuration: 11/53 (11-tooth sprocket / 53-tooth sprocket)
Number of links: 130
Roller width: 6.35 mm
Tensile strength: 6,500 N (suitable for up to ~25 HP)
Weight: 0.75 kg / 100 links
Color: steel / steel
Relative lifespan (for 100 links): 200

High-strength steel chain and sprockets ensure controlled wear and precision machined teeth for accurate engagement. Ideal for mopeds and small 50 cc motorcycles — for example: APRILIA SX 50 (2014) — this kit offers a reliable solution to refresh the transmission and regain smooth and responsive riding in urban environments.
