Product details :

Features

EK/PBR 520M3 14/51 Chain Kit - Ultra-light Sprocket by EK CHAIN: a kit designed for motocross where every gram and every link matters. This kit combines a robust 520 chain with a 14-tooth sprocket and an ultra-light 51-tooth aluminum rear sprocket, creating a transmission set suitable for the demanding terrains of off-road competition.

Compatibility: Universal Cross — e.g., YAMAHA YZ 450 F (CJ06) 2005 – 450 cc.
Manufacturer Reference: Not provided.
Technical Specifications:
- Pitch: 520
- Number of Links: 116 (to be shortened according to installation)
- Color: Gold / Gold
- Sprocket Material: Aluminum (ultra-light)
- Weight: 1.36 kg / 100 links
- Relative Lifespan Index: 450 (manufacturer value for 100 links)

The gold finish provides a race look while the aluminum sprocket reduces unsprung mass for better rear-end responsiveness. Designed for motocross riders, this kit emphasizes abrasion resistance and reliable tension to tackle jumps, ruts, and abrasive surfaces. Check the number of links and installation spacers before mounting; adaptation and adjustment by a professional are recommended for optimal performance.
