Looks like the latest European motorcycle marque from the past to be resurrected is SWM.
The Italian company was founded in 1971 and well respected for building quality enduro, motocross and trials machines. Back then their bikes were powered by Sachs, and in later years, Rotax engines. But all that ceased in 1984 when SWM folded.
Last year the company assets were acquired by Ampelio Macchi and the return of Speedy Working Motors began formulating. A former Husqvarna factory in Arese is tooling up for production. Cash from China is financing the endeavor, though Macchi plans to keep production in Italy. A range of on and off-road motorcycles are being planned as the beginnings of a dealer network are being formed.
We wish them buon fortuna!
