This 1963 Zundapp KS50 Super was purchased new as a 16th birthday present for a farmer in Montrose Colorado. Reportedly stored in a barn since 1983, it was eventually acquired by the seller in 2014. Powered by a 50cc 2-stroke single with a 4-speed transmission, the bike was treated to a refurbishment which included re-sealing the engine, fresh paint, and upholstery. Just under 4k miles are shown, of which the seller has added approximately 200 since the refurbishment was completed. This Zundapp is offered at no reserve with a service manual, parts book, bike cover, and a clean Colorado title in the seller’s name.
The body work was media blasted and the fenders were repaired before refinishing in white by Kustom Coach Werks in Grand Junction, Colorado. The seat was recovered, and the trim, badging, and decals replaced. New rear shocks and brake shoes were fitted, along with an aftermarket tail rack.
The KS50 was made primarily from aluminum, only the front fender and fuel tank are steel. A dent is noted in front fender from impacting the horn, and the forks will require rebuilding.
The headlight shell contains a 60-mph speedometer and the ignition switch. As part of the refurbishment the control cables, hand grips, wiring, and lighting were replaced. The horn is not wired. 3,909 miles are currently shown on the five-digit odometer.
Power comes from a 50cc 2-stroke single with a 4-speed transmission and enclosed chain drive. The engine was reportedly rebuilt with new seals, gaskets, and clutch discs. The exhaust system was also replaced, and a new chain fitted. No service records are available, but the seller will provide notes and pictures of all work performed as well as the removed parts.
