Suitable for cross machines, this kit is particularly well-suited for the listed vintage models (e.g., HUSQVARNA CR 125 - 1992/1993/1994), provided that the length and desired final ratio are checked. The anodized finish of the sprocket minimizes surface wear and offers a balance between lightness and strength.
Before installation, check the 520 pitch, the number of links, and the available space on your swingarm. Manufacturer reference: Not provided. For competitive or recreational use, this kit remains an aesthetic and technical option for those looking to replace the chain and sprocket/sprocket in one operation.
