Features

EK/PBR 420SR Chain Kit 13/51 - Ultra-Light Sprocket

Designed for urban two-wheelers and small displacement bikes, this EK SR chain kit combines strength and lightness. The SR series features a design that maintains the chain's flexibility even after prolonged use: the plates undergo a specialized heat treatment that enhances their durability and wear resistance without stiffening the entire assembly.

Pitch: 420
Number of Links: 136
Sprocket: ultra-light aluminum to reduce unsprung weight
Chain: steel/steel finish
Weight: 0.75 kg / 100 links
Relative Lifespan: 200 (value for 100 links)
Mounting Representation: 13 tooth sprocket / 51 tooth sprocket

Ideal for daily urban use, this kit is aimed at riders seeking a reliable and lightweight transmission for their 50cc bikes. It is particularly suitable for BETA RRT 50 ENDURO TRACK, RRT 50 ENDURO RACING, and RRT 50 ENDURO (2013) models. Standard mounting on shafts with a 420 pitch; regular inspection and tensioning are recommended to optimize longevity.
