The ultra-modern saddle tank and 19-inch high-pressure tyres gave this motorcycle a new appearance. As a typical German utility motorcycle that was economical, undemanding and yet robust, the TS model series remained a successful item in the NSU range for twelve years. The segment gearshift located on the right of the tank contributed to the absolute improvement in ride comfort.
