Features

EK/JT 520SRX2 Chain Kit 13/50 - Ultra-Light Sprocket
Brand: EK CHAIN — Cross Special. This 520SRX2 chain kit combines a robust chain and an ultra-light aluminum sprocket to meet the demands of off-road riding. Designed for aggressive climbs and jumps, it offers a combination of lightness and reliability suitable for 125cc cross bikes.

Composition: steel chain / ultra-light aluminum sprocket
Tooth Reference: 13 teeth sprocket / 50 teeth sprocket
Number of Links: 114
Pitch: 520
Relative Lifespan: 3300 (for 100 links)
Weight: 1.54 kg / 100 links

Easy installation to replace the original transmission on many cross machines. The aluminum sprocket reduces inertia without compromising engagement, while the SRX2 chain benefits from EK's expertise, known on tracks and trails. Ideal for riders looking for a good balance between weight and strength.

Compatible Motorcycles (examples):

BETA RR 125 2T X-PRO (2026)
BETA RR 125 2T RACE (2025)
BETA RR 125 2T RACING (2024)

Kit intended for cross use: check the number of teeth and the number of links for a perfect fit to your motorcycle before installation.
