Technical details
The fuel consumption at 60 km / h was 2.75 liters / 100 km. The crankshaft had three roller bearings and one ball bearing. All bearings were lubricated by the gear oil. The fuel-air mixture came from a Bing two-slide carburetor model AJ 2/22, from KR 25 HM model AJ 2/24. The four-speed gearbox followed the 1-0-2-3-4 gearshift system, the rear wheel was driven by a roller link chain made up of 120 1/2 × 5/16 inch rollers. The final ratio to the rear wheel was 1: 2.69 in solo operation and 1: 2.86 when using a sidecar. A Noris alternator (MLZS 45/60/1 L) with a mechanical regulator supplied Bosch brand spark plugs with a heat value of W 195 T1 or Beru K175b 1 / 14U - only W 225 T type spark plugs were used when the temperature was high. The chassis with a wheelbase of 1,375 mm had a ground clearance of 125 mm (unloaded) or 115 mm (loaded).
