EK/PBR 520M3 Chain Kit 13/51 - Ultra-Light Sprocket

Designed for motocross and amateur competition, this EK CHAIN kit combines a high-performance chain and an ultra-light aluminum sprocket. The set aims to provide a balance between lightweight and durability for machines subjected to off-road conditions.

• Configuration: 13-tooth sprocket / 51-tooth sprocket (13/51)
• Pitch: 520
• Number of links: 112
• Color: Gold/Gold
• Sprocket material: Aluminum (ultra-light)
• Weight: 1.36 kg / 100 links
• Relative lifespan: 450 (for 100 links)

The 520M3 chain is designed to minimize friction while providing good tensile strength and abrasion resistance. The aluminum sprocket reduces unsprung mass for a livelier rear wheel behavior — an advantage on jumps and accelerations out of corners. The gold finish withstands the rigors of the terrain and facilitates visual inspections during maintenance.

This kit is suitable for motocross bikes such as the KAWASAKI KX 125 (2003) and other machines equipped with 520. To ensure longevity and safety: regularly check tension, lubricate after cleaning, and replace at the first signs of wear.
