MZ Specs list

Postby alexxx » Wed Apr 05, 2017 5:29 am

Hi Folks,
As I am new to MZ's I find I have questions regarding the correct spec for an MZ model and year,
I have asked questions about which instruments for model year, battery specs, all answered by forum members. I have looked online for exact specs but info is sparse or partial.
I have had good help from this forum by riders who truly know their machines so I was wondering if we could all contribute our knowledge by listing models then adding/editing specs as we know them for others to use? maybe they varied by country?

I am unsure of what should be original on my MZ ETZ 251(made 1991 UK reg 1992)
Things like
does it have points or electronic ignition, what year did that happen, were there further changes regarding ignition types
instrument changes, I have the squarer clocks.
should the side panels and front mudguard be aluminium? all my panels are magnetic except the left side panel, no big deal , just curious
What colours did they come in.
basic newbie questions I guess

hi alexxx.

Do you have a manual for your bike? if not this may help.

Even the Haynes manual is better than nothing.

Please post pictures of your bike :)

I have had my 1990 ETZ 251 for almost 1 year now (though I have had an 1987 ETZ 250 (with 300 piston) since 2012. Quite difficult animals In my opinion.

The ETZ251 is a complicated machine as it spans relatively few years with quite a few modifications, esspecially as it changes manufacturing hands.

The original ETZ251 came out in 1989 and I am really not sure (I would like to be clarified myself), whether the points ignition was the only option for that year, or whether it was the 'base' bike and the electronic ignition being extra. It definately had both out at the same time I believe, and then more confusion is that the electronic ignition came through two iterations whilst being made in Zschopau. Up until 1991.- so there are three ignition systems from '89-91. I am not too clear on after that point, but the Saxon's didn't come out until '92, which is what presumably yours is. Which included the square clocks (in KM only!), and an electronically driven tachometre. So another iteration type of the electronic ignition! More plastic items (such as front mudguard)- and light unit. I never knew, but I guess the airbox was made into plastic too instead of metal.

In late 90/early 91 on the DDR made 251, the rear mudguard was changed from metal to plastic and that was the start of the conversion to the cheaper materials. Other than the fact that the 251 was shorter than the 250 which encourages manoeuvrability but also kept it in-line with the few years released etz125/150 models. I believe the frame is exactly the same, so saving production variations there..! The reversion to the 16" rear wheel was also put back into force with the 251. I'm unsure why, possibly because they were also cheaper to make (being smaller), also because of reasons above, plus the fact that the 16" wheel is easier to remove from the bike without having to tilt the bike at all.. The ETZ250 was the only one with 18" rear wheel and it is noticably more difficult to remove. ETZ251 also had a shorter exhaust to accompany the fact that the bike was shorter. I am unsure however what that had (if any) on the performance. Apparently there is a difference, and I can feel it. But there are so many factors like the engine health and fuelling which could also obviously change this.

Do not forget that after 1991 and the takeover, the carburettor had changed from the BVF 30-N3 (which I really rather like!) to the Bing carburettors.


My ETZ251 had a points ignition on it when I got it, and I would have continued to use it but HAD to purchase one of the many aftermarket electronic ignitions around now which has certainly given me peace of mind, and clear thinking when running faults arrise (Ie-not blaming bad running on wear on the contact breaker). Mine is the Polish made Zapłon ignition with LED timing light on the electronic unit (which is oh so lovely to have!). I do wonder how long it would last though? - Presumably the length of the bike.



BTW. My signature link to my FTP holds most information I have concerning the MZ's...

Thanks Blurredman,
Excellent and so helpful, this is exactly what I meant by a database of our own machines as we know them.
My bike is not a saxon but is in between the earlier ETZ's and the Saxon's.
I have not opened any cases yet but I am keen to find out about the ignition so will open it up soon.
My bike's vin plate says 1991 but was first registered in Oct 1992.
You are correct I think 90-93 seen a lot of changes in the ETZ bikes that is why I am unsure about what my bike should have as standard.
I need to fix a leaking caliper and not sure which model it is, seems there was a change in seal type in 1991 so it could be either..I always seem to be in a model parts change year.
Here is a pic of my bike and the instruments.

Hey Blurredman,

I notice on ebay UK there are a few MZ ETZ's and all have a rack and the same topbox, my bike is the same, this must have been an importers decision.
Strange but true?

I'm not sure on the top box question as officially there was no rack released for the ETZ250 or 251.. And the racks that you do find on them are modified in some way. Mine actually came from a MZ TS250 and unfortuantely broke in two places straight through!! Very annoying.. I like having a top box to keep my tyre irons, spare tubes, some tools and general stuff in. Grr! That rack is not one i've seen before actually.


From the pictures.. Your bike has definitely been modified!! I like that front mudguard ornament though haha! It's got later clocks, including indicators and ignition barrel.
It also has an aftermarket/new replacement exhaust for a 250. It's quite a bit longer than an original 251 exhaust.. But they perform the same really. I have a replacement one on my 250 they're fine if a bit noisy. I guess it's been crashed or at least dropped because the right hand side foot rest is bent up, which I suppose is also why the exhaust was replaced (not least because the original exhaust chrome on MZ's is quite poor really), because it would have been scratched considerably. The horn is also replacement and the seat has been re-upholstered.

all well spotted, thanks.
Exhaust seems newish and quiet.
I think these clocks/fairing are correct for that year, check out ebay today, you will see a 301same year with the exact same setup

Can anyone confirm the above? I never saw an official model like yours alexxx.. Esspecially because I am in doubt they would have two styles of indicators.. Early 251's had those indicators on your rear at the front as well. :lol:

Heck, it's easy to do small modifications like that. Open up your generator cover.. I am entruiged as to what electronic ignition it has (if at all)- and how that rev counter is therefore powered.. :)

When I got my 251, the rear light was broken, which as you may know is a bi-lux bulb on the later 251's. I put on an older Round two bulb rear lamp. No modification required either bolt wise. Just an extra small wire needed to bridge the earths between the bulbs. :D And one of my indicators on the front is the rear of a TS/ETZ250 model seeing as I had plenty of those spare.

Hi Blurredman,

All I confirm at the moment is that the rev counter is electronic, no cable drive from the engine to it.
Have a look at this bike pic that is on ebay today, it is am MZ ETZ 301 1992..looks exactly the same as my bike (apart from rear indicators which on my bike must be from an older model, the ebay one will be correct I think) that is why I think it may be standard?

Interesting point. I forgot about that varient. I didn't realise they were as early as it is apparent. 8)

looks like it is a model between the older ETZ's and the later Saxons, maybe from 1991-1992?
Even has a rack and topbox! the topbox looks exactly like mine (Rickman)
Wish we had some factory model history for these later bikes from 1990 onwards.
Hey..I may have a super rare model ! :D

Hi alexxx.

It looks to me like your bike is a later version of the original ETZ251 model, the only thing different is that you should have black painted engine side cases, though these could have been replaced/polished.

Your front brake, master cylinder, caliper, brake disc, is the same as earlier 125/250 models from about 1983-4, parts for the master cylinder are I think getting rare. Update. it's the complete master cylinder thats rare/ unobtainable in the UK, repair parts are ok.

If your rev counter is electronic then you have electronic ignition.

Have you considered joining the MZ Riders Club, there you will be able to get any information on your bike, are a great set of people, and have a south of Scotland section.
