Lot 409: 1928 Rex 350cc Racing Motorcycle

Collectors' Motorcycles, Bonhams (16 October 2005)

Not to be confused with the British Rex (Rex-Acme) concern, the Swedish Rex company was founded in 1908 in Varberg. Swiss Motosacoche engines were used at first before Rex introduced its own 2.5hp v-twin. JAP and Villiers engines also were fitted, while after WW2 Husqvarna, Ilo and Sachs units were used to power a range of two-stroke lightweights. In the late 1920s Rex enjoyed considerable success with their racing machines, which were assembled in Sweden using British Sturmey-Archer (Raleigh) overhead-valve engines and Burman gearboxes.

This rare Swedish racing motorcycle was ridden to victory by Gunnar Karlsson in the Swedish TT at Onsala in 1929. Gunnar was the brother of Sarolea rider Hugo, winner of the 500cc class at the same meeting. After its racing career was over, the machine was rebuilt as a sports roadster at the Rex factory in Varberg and then sold to a local fisherman in Karl Oskarssonís home village, Valdemar Petterson. Petterson used it from the late 1930s to the 1950s and then took the Rex off the road, storing it in his shed. Karl Oskarssonís son Ola found the machine at the Petterson home some 35 years ago. His father Karl restored the Rex in 1990, returning it to racing specification, and since completion the machine has been ridden by Karlís daughter Rebecka in a handful of classic races. The vendor reports that the Rex is a very reliable machine presented in good running condition and ready to race or parade. Documentation, race programmes and contemporary photographs are included in the sale together with assorted road equipment comprising lights, mudguards, silencers and some other more minor parts.
