EK/JT 520M3 Chain Kit 13/48 - Ultra-Light Sprocket
A chain kit designed for motocross riders seeking lightness and reliability on demanding terrain. This complete kit (sprocket, crown, chain) combines a gold-plated 520M3 chain and an ultra-light aluminum sprocket to reduce unsprung mass without sacrificing tensile strength and abrasion resistance. Gold/Gold finish for a polished racing look and better protection against corrosion in muddy conditions.

• Pitch: 520
• Composition: gold chain / ultra-light aluminum sprocket
• Ratio: 13/48 (13-tooth sprocket / 48-tooth crown)
• Number of Links: 114
• Weight: 1.36 kg (for 100 links)
• Relative Lifespan: 450 (based on 100 links)

Designed for the motocross universe, this kit is particularly suited for compact models such as the SUZUKI RM-Z 250 (2004–2006). To preserve the chain and sprocket, always check the tension after the first rides, lubricate regularly, and inspect tooth wear before each outing.
