Joining the single speed 48 Brisk was the 1968 Rolly with the same
single-speed engine in a steel chassis with no rear suspension.
The fork was a rudimentary hydraulic telescopic fork and the
headlight the later Piuma angular type.
The Rolly continued after the demise of the Brisk, but by this time
there was no maket for mopeds.
