Moto SWM


SWM (Speedy Working Motors) was founded in 1971 by Piero Sironi and Fausto Vergani and was based in Milan, Italy. SWM manufactured  Trials, Enduro, Motocross and off-road motorcycles in the 1970s and 1980s.


They started with small capacity Sachs engined enduro bikes and began making Rotax engined trials bikes in 1977. 


They started making Rotax TL125 and TL320 trials bikes in 1977. Rotax built a special trials version of their rotary valve motor, with development input from Sammy Miller and Charles Coutard. Acerbis made the plastic mouldings, and suspension was by Marzocchi. These first trials machines were red and white.


In 1979 yellow and black models appeared, and in 1980 these were fitted with Girling Gas shocks and Betor forks. Gilles Burgat won the 1981 Trials world championship on an SWM.



In 1982 a 240 model was produced with a blue frame, acknowledging Pernod's trials sponsorship.

In 1983 all bikes got alloy swing arms, and the TL350 Jumbo was introduced. This was a new reed valve motor with the same yellow and blue colours.


In 1984 the 125 and 320 were put in the new Jumbo frame, but then production ceased.
