In concept, although not in actual design, it was an extended version of the Fend Flitzer invalid carriage. Approximately 15,000 were built before it was replaced by the Messerschmitt KR200 in 1956.[4] HistoryMesserschmitt, temporarily not allowed to manufacture aircraft, had turned its resources to producing other products. In 1952, Fend approached Messerschmitt with the idea of manufacturing small motor vehicles.[5] These were based on his Fend Flitzer invalid carriage.[6] The first of Fend's vehicles to enter production at Messerschmitt's Regensburg factory was the KR175.[3] The title Kabinenroller means "scooter with cabin".[7] While the Messerschmitt name and insignia were used on the car, a separate company, incorporated as Regensburger Stahl- und Metallbau GmbH, was created to manufacture and market the vehicle.[3] There were several problems with the first KR175s to be built, resulting in 70 design modifications between the beginning of production in February and June 1953.[4] The KR200 was developed from the KR175 and replaced it in 1955.[3] Features{{See also|Messerschmitt Kabinenroller}}Being based on the Kabinenroller platform, the KR175 had tandem seating accessed by a hatch that opened upward and to the right. The standard version of the KR175's hatch had a canopy made from a large Plexiglas dome with a cutout at the front for a small, flat glass windshield and a cutout on either side for the frames for the sliding windows.[2] A "sportster" model was available without the dome or the windows, with only the windshield attached.[6] The windshield wiper was manually operated.[6] The front fenders did not have wheel cutouts.[6] Engine and transmissionThe KR175 ran on a {{convert|173|cc|CID|1|abbr=on}} Fichtel & Sachs air-cooled single cylinder two-stroke engine positioned in front of the rear wheel,[2] just behind the passenger's seat.[6] The engine was started with a pull rope as standard, but there was an option of an electric starter.[2] The electric starter became standard in 1954.[3] The transmission was a sequential, positive-stop type with four speeds and no synchronization nor reverse gear.[2] ControlsThe KR175 used the standard Kabinenroller steering system, with a steering bar connected directly to the track rods of the front wheels, providing an extremely direct response best suited to small, measured inputs.[3] The KR175's steering bar was made from tubular steel. The gearshift lever, on the right side of the cockpit, had a secondary lever on it which operated the clutch.[2] The throttle was operated by a twist-grip on the left handlebar.[3] The foot brake pedal, which was the only pedal in the car, operated brakes on all three wheels mechanically, using cables. The handbrake lever operated similarly.[2] In 1954, the clutch lever was replaced by a pedal.[3] MI-VAL MivalinoItalian motorcycle manufacturer Metalmeccanica Italiana Valtrompia s.p.a., makers of the brand {{Interlanguage link multi|MI-VAL|it|MI-VAL}}, assembled KR175s in Brescia, Italy, using components imported from Messerschmitt but with their own {{convert|172|cc|CID|1|abbr=on}} two-stroke engine installed. These cars were sold as the MI-VAL Mivalino.[1] Data
