Question to /43 rear wheel suspension

Post by martdapp » Fri Oct 07, 2016 5:46 pm

In the case of the 43 series numbers 608501 and 612000 are supposedly 3000 NZ's with rear wheel suspension built. Is the suspension attached to this / 43 original?
frame number 6100019

Hi,

The question about the rear suspension has also bothered me. Were these -43 bikes with rear suspension (according to the list) manufactured in the reality? I have never seen a war time picture of a -43 NZ with rear suspension. Is there someone who knows about/have a such picture?

Hi,

That's an IZH suspension. The NZ with rear suspension used the NZ500 rear. Why they were produced....no idea. But definitely they existed, I have seen one myself.

Ok, many thanks for the info.

It is also not a Jurisch suspension and definitely not original DKW

If it had been 3000 produced why are there no pictures on them? There should be considerably fewer that have been manufactured.

What is the logic to manufacture a large number of motorcycles with a much more advanced design when the army is screaming for more of everything? It is the spring of 43 just months before the more field suited 350/43 goes in production and this appears to be a step in the opposite direction? In case of a shelf cleaning on a small number (300 pieces?) of rear frames from NZ 500, it becomes more logical.

I have seen a similar plunger suspension on another rear frame to NZ 350 that had a spring over the hub and another under the hub but it was some years ago.

Another thing that I reacted to is that the sign plate seems to sit on the side of the frame with the frame number punched to the right of the sign. My 43 has the frame number 610303, it has the sign plate right in front and the frame number punched on the right side of the frame. My frame number begins and ends whit a star. If I remember it correctly so the later NZ has the plate on the right side of the frame with the frame number punched to the left of the sign.

Hello NZ people , this is an nice topic!!

Aldo i am short of info on this one , could it be that the rear suspension was planned for an upgrade , do to the ruff roads in the east /Russia , may be there are some ducuments about that ???

An other thing is a lot of parts suppliers where Bombed too , may be there is some info on that ??

I realy dont have the total awnsers but a rear suspenseion could help a lot in bad terrain!!

1943 the german were deep in Russia i believe ?? the roads in west Europe where not that bad for an need of that rear suspension!!

just some stuff to think about!!

Greats

Motorboy.

Well, I feel more for the topic from Asplund.
300 left-over suspensions from the NZ 500 would be plausible, 3000 is way to much in my opinion too.

Question stays;
1. Why they started to produce 350th with rearsuspension
2. Why they stopped this production
3. Could anyone show the original records that they realy produced 3000 NZ350/43 with rearsuspension.

Hi Guys,

I also put my spoon in this soup :lol:


If you check the DKW "Fahrgestell nummern" list, it seems that when it ends in 1942, the following series are still not manufactured yet.

http://www.dkw-nz.net/cms/upload/img_pd ... tellnr.pdf


For the manufacturing number series 608501-609000 it says "Noch Offen" (Still Open) and there is no info about the type of the bikes or the parts catalogue for this series.

On the following series "609001-612000" it says "NZ350 Mit Hinterradfederung" (With rear suspension).

In my opinion this means the last war time update of the list was in 1942 and the bikes from 608501> were still not manufactured when this list was made.
Probably they had planned to start with rear suspension then, but as Asplund writes, a rear suspension was probably not priority one on the "to-do-list" anymore at this period of the war.

I have seen some bikes in the span 609001-612000 and they have all had the normal rear end, without suspension. I know that forum member Asplund also has a bike in this span (without suspension).

Neither do I believe that 3000 of those with suspension were manufactured during -43, but fully possible some bikes were manufactured with leftover parts from NZ500?
