A small 305 cc parallel twin aimed at city and suburban riders who wanted simple, low-maintenance transport with enough power for expressways. It used a belt final drive so no chain lubrication was needed, a low seat height and a six-speed gearbox. The CSR name marks it as the sports-styled version of the 305 range from the early 1980s.
