Bremen Classic Motor Show: Motorcycle special show shows two- and four-stroke in retrospective

 

Generations of motorcyclists, motorcycle buyers and motorcycle designers faced a big decision: What drive should their two-wheeler have – two-stroke or four-stroke engine? There were technical, financial, tax, regulatory and above all emotional arguments for one or the other decision. It was pondered, considered and discussed, planned, rejected and enforced. From the beginning of the 20th Century to the 1990s, the progress of one construction challenged the designers of the other construction method. Reason enough to review this decadelong coexistence – as a motorcycle special show at the 20th Bremen Classic Motor Show from Friday to Sunday, 4th to 6th February 2022 at MESSE BREMEN.

The two-stroke with its double ignition sequence and its few moving parts has always been a smart seduction for designers and merchants: Inexpensive production, light weight and good power yield were contrasted with problematic lubrication, high fuel consumption and treacherous gas change. Four-strokes, on the other hand, demanded investments from producers as well as buyers. They convince with disciplined running and lower fuel consumption. But higher weight, more complex maintenance and costly repairs had to be accepted.

 

Special show: Second and four-strokes of all classes to be seen

In popular opinion, two-strokes are ordinary, healthy and strong, while four-strokes are considered cultivated, heavy and care-intensive. There is as little better or worse as the world is black and white. Polarizing couples from the PS.Depot motorcycle of the PS.SPEICHER from Einbeck show at the Bremen Classic Motorshow how two- and four-stroke animated the scene over all decades in all displacement classes, all vehicle categories and all nations and found convinced advocates who also changed camps the next time they bought. 110 years ago, the ease of use of the Scott twins and their sporting successes rocked four-stroke dominance. Only elaborate four-strokes restored the old order in sport. From the Scott Squirrel from 1920 to the 1989 Yamaha RD 350 YPVS, it was a long way for two-stroke technology. In the four-stroke, the Bremen arch is stretched from the exemplary Douglas Boxer from 1922 to the revolving Honda CB 1 – 400 from 1989.

 

Two-strokes and four-strokes of all classes meet between these poles in Bremen: The cult bikes Honda Dax and Simson Schwalbe like the little-known scooters Moto Guzzi Galletto and Progress Strolch. Of course, the superbikes of the Glamrock era such as the Honda CB 750 Four and the Suzuki GT 750, the legendary water buffalo. Sporty 250s already existed in the 1930s with both drive concepts, the lightweight BMW R 23 and the complex Triumph BD 250 (both from 1939) show how progress was boosted in the important 250 class. The Gilera 150 Rossa Super from 1958 and the DKW RT 175 S show how different everyday machines with sporty driving characteristics could be from the end of the 1950s. At least 20 motorcycles will be on display.

 

Bremen Classic Motorshow 2022: 2G rule and no mask requirement

This year, the classics fair had to take place as an online edition due to the pandemic and received a lot of praise from the scene for it. For 2022, it is considered certain that the anniversary edition will take place again as a face-to-face event – under 2G conditions. Therefore, only persons with a proof of vaccination or recovery have access. If you are not vaccinated for medical reasons (certified by a doctor), you can visit the Classic Motorshow with a daily negative test. With this solution, we want to enable a high degree of security and a piece of normality, says project manager Frank Ruge. Because the 2G rule also eliminates the mask requirement.

 

The Bremen Classic Motor Show takes place from Friday to Sunday, 4th to 6th February 2022, in all halls of MESSE BREMEN under 2G conditions. Current information about the event and hygiene concept at www.classicmotorshow.de.
