SWM (motorcycles)

SWM was founded in 1971 by Piero Sironi and Fausto Vergani and was based in Milan, Italy. SWM manufactured Observed Trials, Enduro, Motorcross 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. The other main manufacturers at this time included Fantic Motor, Bultaco and Montesa. Trials Bikes SWM 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 and frame wearing the same yellow and blue colours. In 1984 the 125 and 320 were put in the new fra

e, but then production ceased. [edit]Enduro Bikes SWM RSGS and SWM TF1 in capacities 125, 175, 250, 350, 370, 440, 506 Joan Riudalba, riding an SWM TF1 of 125 cc was Enduro Spanish Champion in 1980. When SWM went into liquidation Armstrong of Bolton, England bought the rights to the SWM XN Tornado, a Rotax engined enduro machine of 350cc or 506 cc. With CCM, Armstrong developed and marketed a military version, the Armstrong MT500, which was so successful Harley-Davidson bought the manufacturing rights in 1986, and further developed the bike as the MT350E. Motorcycle trials, also termed observed trials, is a non-speed event on specialized motorcycles. The sport is most popular in the United Kingdom and Spain, though there are participants around the globe. Trial motorcycles are distinctive in that they are extremely lightweight, lack seating (they are designed to be ridden standing up) and have suspension travel that is short, relative to a motocross or enduro motorcycle. Motorcycle trials is often utilized by competitors of other motorcycle sports (such as motocross or street racers) as a way to cross-train, as trials teaches great throttle, balance, and machine control.
