EK/PBR 520MRD7 Chain Kit 14/48 - ultra-light sprocket by EK CHAIN: a set designed for motocross and use in off-road environments. This kit combines a robust 520 chain and an ultra-light aluminum rear sprocket to reduce unsprung mass without compromising abrasion resistance and traction essential for competition.
Ideal for motocross riders looking to lighten their final drive while maintaining a treated chain to withstand the rigors of the track (mud, sand, stones). The gold anodization makes it easy to spot and provides a polished finish on prepared machines.
Top 3 compatible motorcycles (for reference): KTM 250 EXC SIX DAYS (2004), KTM 250 EXC (2004). Manufacturer reference: Not provided.
