Specifically designed for off-road use, this JT DRIVE CHAIN kit combines a super-reinforced HDS type chain and an ultra-light aluminum sprocket. It features a meticulous black/steel finish, robust components, and XS-Ring seals to ensure the protection of the lubricant between the links during Cross sessions.

• Type: 520HDS chain kit, 13 tooth sprocket / 51 tooth sprocket (standard)
• Chain: Super-reinforced, black/steel color, links treated for intensive use
• Seals: XS-Ring — better sealing compared to standard seals
• Sprocket: Ultra-light aluminum, designed to reduce rotating mass
• Usage: Cross Universal — suitable for off-road stresses and frequent RPM changes

Standard mounting and adjustment like a classic 520 chain. Ideal for riders looking for a robust, compact, and lightweight transmission on the sprocket side. Compatible with many motocross bikes, including the KAWASAKI KX 125 (2003). Be sure to check the tension adjustment and lubrication before the first ride.
