The EK/PBR 520MRD7 13/52 chain kit is designed for motocross riders seeking a robust and lightweight transmission to tackle the tracks. Developed by EK CHAIN, this kit combines a high-performance chain with a 520 pitch and an ultra-light aluminum sprocket to minimize unsprung weight without sacrificing durability in intensive use.
- Configuration: 13-tooth sprocket / 52-tooth sprocket
- Chain: 116 links, 520 pitch, Gold/Gold finish
- Sprocket: ultra-light aluminum to reduce inertia
- Durability: relative index 450 (reference for 100 links)
- Weight: 1.47 kg / 100 links (manufacturer's value)
- Usage: developed for the demands of motocross, training, and competitions
The chain features a gold finish that protects against corrosion and facilitates visual wear monitoring. Delivered with 116 links, it can be shortened to fit the specific setup of your machine. This kit is particularly suitable for recent cross models such as the KTM 350 EXC-F (including SIX DAYS and FACTORY EDITION), but is compatible with any motorcycle that accepts a 520 pitch and the 13/52 configuration. Ideal for riders concerned with reducing weight and ensuring the reliability of their transmission on challenging terrains.
