Another important part of the bike's equipment is the speedo. There is a lot of variance in the speedometers on these NZ bikes. Over time people change speedometers and replace them with anything that will work.
This page presents the original speedometers used on the NZ 350 and the NZ 350-1.
For the earliest NZ 250 and NZ 350 models the Parts list no. 58 lists only the 80mm P&S speedometer no. 31 (left).
From what we gather from the parts manuals, on the NZ 350 throughout its production DKW used both the 80mm ISGUS and P&S speedometers.
On the picture above, the speedometer no. 31 (left) is manufactured by P&S, the speedometer no. 33 (right) is made by ISGUS. Please note that on both speedometers the needle turns clockwise, starting at the one o’clock position.
On the early NZ350-1 the 80mm ISGUS speedometer was used, and on the later ones a 60mm speedo.
The DKW NZ 350-1 manual D 605/27, dated 5.08.1944, pictures the early NZ350-1 speedometer which is the ISGUS speedometer no. 33 shown above.
An original ISGUS speedometer has the following characteristics:
- The lettering is printed (not etched) on the backside of the glass in white. (New glasses are again available)
- The ring under the white lettering is in a matt dark grey
- The base plate, where the needle rests on, is completely semi gloss black without any white/beige circles on it.
A discussion in the forum revealed, that most probably 60mm speedometers from ISGUS, P&S and VDO were used for the NZ350-1. Please note that the 350-1 speedo only read up to 100 kmh instead of 120 kmh for the earlier bikes. Following are some pictures of a ISGUS speedo marked 9/44.
