Still more impressive for young German customers was the 50cc MD Maico (pictured above). Because this small motorcycle could be legally ridden at age 16, it was on every youngster's mind as a serious contender in a comprehensive fleet of German brands providing similar products. The advertisement spoke of 6.3hp in 1971, which was a pinch more than even Kreidler's 50cc Florett could offer at 6.25hp. What seems to be an academic difference today could be THE deciding factor for young purchasers at that time, not to mention the technical appeal of a six-speed gearbox and rotary disc valve!

Regrettably, with all that "bred of the racetrack" feeling, there was also a reputation of “for experts only.” Occasionally seizing pistons, even if not totally unknown by riders of Hercules, Zündapp or Kreidler 50cc motorcycles, were said to be caused by "overtuning" the engine. So market share remained low despite the bike's outstanding performance, demonstrated by Maico riders who painstakingly did their jetting homework and kept the carburetor's rubber seal tight.
