JT/PBR 520HDS 12/50 Chain Kit - Ultra-Light Sprocket

Designed for motocross and vintage 125cc motorcycles, this JT DRIVE CHAIN kit combines a super-reinforced HDS chain with an ultra-light aluminum sprocket. The set features a sleek black/steel finish that easily integrates into a competition or leisure machine requiring reliability and compactness.

• Type: 520HDS Chain Kit (super-reinforced chain)
• Pitch: 520
• Sprocket / Sprocket: 12/50 (ultra-light aluminum sprocket)
• Seals: XS-Ring to limit lubricant loss and dirt intrusion
• Color: Black / Steel
• Universe: Motocross — compatible notably with KAWASAKI KX 125 (years 1982–1984)

The HDS chain combined with XS-Ring seals aims to provide increased resistance to stress while facilitating maintenance. The aluminum sprocket, designated as "ultra-light," helps reduce peripheral mass compared to a steel sprocket, without altering the original architecture of the transmission.

Standard mounting on 12-tooth sprocket and 50-tooth sprocket. Before each ride, check tension and lubrication: regular maintenance prolongs the lifespan of your transmission and ensures more consistent performance on muddy or sandy terrains.
