Lineage:
The XL series was Honda's long-running line of dual-sport motorcycles, evolving from smaller displacements to larger ones like the 350cc. The 'R' designation typically indicated a more 'race' or performance-oriented version, often with improved suspension and engine tuning compared to standard models. The XL350R was a successor to earlier 350cc models and a precursor to later XR and XL variations.
Production Years:
The XL350R was produced for the 1984 and 1985 model years. It was succeeded by models like the XR350R and later iterations of the XL line.
