This 1959 Zundapp Bella R204 was purchased from known scooter collector and expert Kevin Johnson. This example is powered by its numbers-matching 200cc two-stroke engine that was rated at 10 horsepower when new and gave the bike a top speed of 75 mph. The scooter has an electric start and 12V power supplied by two 6V batteries. It was cosmetically and mechanically restored in 2008 while still in Europe, and it remains in good condition. This Bella is now offered at no reserve with a clean Washington title in the seller’s name.
Zundapp was a German motorcycle manufacturer that existed from 1917 until its bankruptcy in 1984. After WWII, the company moved from motorcycles and aircraft engines into scooters and smaller bikes, producing the Bella from 1953-1964. Based on the Parilla Greyhound design, the scooter featured prominent air tunnels to allow fresh air to cool the engine without a fan, and existed in both 150cc and 200cc models.
This example shows 27,578km (~17k miles), which is believed accurate but undocumented. The numbers-matching 200cc engine was fully overhauled during its 2008 restoration along with the gearbox and carburetor.
During this time, the fuel tank was resealed and the scooter was fully rewired. The frame was powder-coated and the body received a bare-metal repaint that shows well. Note the signature daisy logo on the legshield. A new set of tires was also installed.
Earlier Bellas featured a telescopic fork but by the late 50s, the front suspension was changed to an Earles-type leading link fork with a single suspension unit.
