DKW
SB-500 and SB-500 Luxus
The DKW SB-500 was builted between 1934 and 1939, where the NZ-500 was born. There were three types the SB-500, SB-500 A and the SB-500 Luxus, equiped with a double front light very impressive, as the Triumph ones.
You can see a lot of differences between the SB and the NZ, the more important are:
- No rear suspension on the SB
- Rear break shift (normal in the NZ, back pedal in the SB)
- No front shock absorver in SB
- The seat
- The mudguards
- The front light
- Lateral cases (clutch and dynamo)
- The cylinder head
- Gas Tank
- Weight
- 4 Gear transmission in NZ and 3 in SB
- Carburetor
- Brake and clutch shifts in handlebar
- Ignition Key
- Claxon
- Rear Light
- Speed Shift only in hand (optional in foot)
Even with those differences they look similar. There were made 19.003 frames of the SB-500 in its three types, and a total of 19.700 engines. (At the end of the page you have the frame and engine numbers, with its made years).
Here you can see Gero´s SB , a Girona´s friend.
