EK/PBR 520M3 13/48 Chain Kit - Ultra-Light Sprocket by EK CHAIN: a kit designed for the cross universe, combining a robust 520 chain with a lightweight aluminum sprocket. Designed for riders who push their transmission off-road, this kit offers a construction focused on abrasion resistance and traction while minimizing friction between links.
The ultra-light aluminum sprocket reduces unsprung weight for better rear wheel responsiveness, while the chain is treated to withstand the rigors of the terrain (abrasion, dirt). This kit is suitable for lightweight and competitive enduro/cross models; installation and adjustment by a professional is recommended to ensure optimal tension and lubrication.
Compatible motorcycles (examples): YAMAHA YZ 125 (2005/2021), YAMAHA TT-R 125 LW BIG WHEELS. Check the number of teeth and pitch for your machine before installation.
