Generations of motorcycle enthusiasts have faced the fundamental decision: What engine type should they choose – two-stroke or four-stroke? There were technical, financial, tax-related, registration-related and above all emotional arguments for each type. From the early 20th century up to the 1990s, progress made with each type constantly challenged engineers working on the other. So it is well worth looking back over these decades of parallel development, in the form of the motorcycle special show at the 20th BREMEN CLASSIC MOTORSHOW from Friday 4 to Sunday 6 February 2022 at MESSE BREMEN.
Visitors to Bremen will be able to see pairs that divide opinion on loan from the motorcycle collection of the PS.SPEICHER museum in Einbeck. They will illustrate how two and four-stroke engines spanning all decades, cubic capacity classes, vehicle types and nations provided fuel for controversy. Each type found its champions, although some jumped camps for their next purchase. Among the stars on show will be the superbikes of the glam-rock era, the Honda CB 750 F1 and the Suzuki GT 750 A, the lightweight BMW R 23 and the complex Triumph BD 250, the obscure scooters Moto Guzzi Galletto and Progress Strolch as well as the Gilera 150 Rossa Super and the DKW RT 175 S. A total of twelve pairs will be presented in the ÖVB-Arena.
