TRIALS MODELS.. 83 >

.. 1983 also saw the introduction of the TL350 Jumbo. The case reed valve Rotax motor was housed in an all new frame which necessitated new Acerbis plastics, new seat and a redesigned exhaust system.
.. The Betor front forks, wheels and alloy swinging arm were shared with the other trials models, unique to the Jumbo however was the clutch lightener system. This involved a two piece cable set up and a reduction arm mounted under the tank, which resulted in a much easier to use clutch than previous models.

1984 TL125/240/320/350 Jumbo

.. Big changes for all 3 disc valve models in 84.
.The motor, carb, airbox and exhaust system from the previous years bike was slotted into the updated Jumbo chasis. This had minor improvements over the original model, which included new 38mm Betor forks and a blue, rather than black, seat.

1981 TL320 SIDECAR...!

.. The SWM factory developed a trials sidecar in 1981, which was never made it into major production.
..The Columbus sidecar frame had yellow plastics that were manufactured by Acerbis with SWM logos moulded into them.

SWM Mono !!

After the demise of the SWM factory in 1984 Mauro Sironi started work on
his SVM trials project which utilised many of the Jumbo's parts including,
frame and plastics. These eventually were produced with a MotoVilla engine,
monoshock suspension and disc brakes.
The development work on the suspension system was carried out by Italian
engineer Marco Mantovani who in conjunction with Sironi produced some
experimental monoshock SWM's

What about MOTO GORI...?

.. Although an entirely separate company Moto Gori and SWM had one common factor, namely SWM boss Pietro Sironi who along with Giancarlo Gori was co-owner.
..After the SWM factory launched the new yellow models in 1980, Sironi used the previous years bike to launch a trials model at Gori. The first of Goris 2 trials models was the red and white SWM painted black with a green steel tank and matching green plastics. The bike was totally SWM even the new green plastics had SWM stamped into them, as did the engine cases, exhaust system, brake plates, seat etc......in fact the only Gori logo was the tank badge.
..The later model offered a choice of 125/200/320(called a 325!) motors and changed from Marzocchi to Betor front forks and Corte & Cosso units, before production ended in 1983.

As you can see from the photo above Martin has a fair collection of SWM's from the various years..!!
