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.
- Kit composition: 520 chain, 112 links, 13-tooth sprocket / 48-tooth sprocket (ultra-light aluminum sprocket).
- Color: Gold/Gold, carefully finished suitable for cross machines.
- Durability: relative lifespan index 450 (reference for 100 links).
- Weight: 1.36 kg for 100 links — approximately 1.52 kg for the 112-link chain.
- Pitch: 520, standard for many trial/cross motorcycles.
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.
