 The resulting 389 cc 2-cylinder 2-stroke powered Staunau Type K400 used a three speed manual transmission and was spectacularly underdeveloped and underpowered, but very competitively priced.The same body was used for the more powerful Staunau Type K750 which employed a four speed manual transmission and was powered by a 748cc 2-cylinder 2-stroke motor.Claimed power outputs for the two version were respectively 9.5 kW (13 PS) and 18 kW (25 PS) which were said to allow for top speeds of 92 km/h (57 mph) and 105 km/h (65 mph).
