Product details :

Features

EK/PBR 520SRX2 Chain Kit 13/50 - Ultra-Light Sprocket
The EK SRX2 chain kit is designed for motocross riders looking for a good balance between durability and reduced weight. Based on the SRX series, it combines a proven 520 chain and an ultra-light aluminum rear sprocket to minimize unsprung mass without sacrificing performance in off-road use.

Type: 520 chain kit (pitch 520) — setup 13/50
Chain: steel/steel, 114 links (indicative weight: 1.54 kg/100 links)
Sprocket: ultra-light aluminum, optimized profile for motocross use
Durability Index: relative lifespan 3300 (for 100 links, manufacturer value)
Usage: specially designed for demanding terrains — jumps, whoops, and aggressive acceleration

This kit is suitable for 500cc motocross machines and is listed for models such as the KTM 500 EXC-F (2022) and the SIX DAYS variants. To get the best performance from this kit, maintain proper chain tension, lubricate regularly, and check for wear on the teeth and links after muddy rides. Brand: EK CHAIN — manufacturer reference not disclosed.
