Designed for urban riding and riders seeking a reliable replacement, this chain kit combines a super-reinforced 420HDR chain with a steel front sprocket and an aluminum rear sprocket. The 12-51-126 configuration corresponds to the number of teeth on the sprocket/sprocket and the number of links provided, ready to equip your drivetrain for improved precision and acceleration response.
The XS-Ring seals minimize lubricant loss and help reduce wear, while the aluminum sprocket lightens the overall setup for improved maneuverability in the city. A complete kit ideal for chain maintenance: weight reduction, ease of installation, and simplified upkeep. Compatibility examples: APRILIA RX 50 (2003–2005).
Biker tip: Check the exact compatibility with your model and adjust the tension according to manufacturer recommendations. For optimal longevity, lubricate regularly and monitor tooth wear.
