MZ ETZ Build from Blackpool UK

Hello from a long time lurker!

I thought it was about time I should step out of the shadows and
share my contraption and story with you guys.
It started just before summer 2012 when I sold my K100 - due to hooliganism
I thought I should get something a little more sluggish. I've always yearned
for a Dnepr rig but nowadays they all seem to be too expensive for what you
get... or don't get for that matter. Instead I bought another ETZ250 as I'm quite
a fan of MZ and decided to go forth and engineer myself a hack!
So armed with a £20 gasless mig, angle grinder and some cider I leaped in at the
deep end.

I had chunk of steel frame that I modified, some spare swing arms and general MZ
parts floating about - the only steel I bought was for the main connection bar & suspension aswell as the diagonal struts. The rest was all skip finds.

Ok there are quite a few photos missing but here is part of the semisubframe without the main structural parts - the chair was originaly tried as a mono-shock but I later found that needed tweeking.
Note: My skills don't result in asthetics, just simple and strong! Plus the uglyness is an anti-theft device in its own right!

After winter I decided I needed a "proper" sized box!



Test for size... also note the upgrade to twin shock.

Struts were 3mm walled tubing with a nut welded onto the end and secured using connectors from scaffolding clamps, I got 6 knackered clamps off a local scaffolder and chopped them up to make my bits, for example, under the tank I welded part of a clamp to the frame. To that connects one of my struts - one end has the nut and connector, the other end I made a slot and in it put a plate of metal with a hole drilled in it - effectivly a fixed and and an adjustable end.
For the main connection to the bike I made a clamp that clamps to the center stand mounts, the inside of the clamp is a kiln dried wooden block - idea being that I tightend it all up good and tight and as the wood gets wet it expands and makes everything a little more snug.

I have a total of 5 connection points, front and rear diagonals, main connection bar, a rear stabiliser bar that connects to the pillion footrest and a bar that runs from the front of the sidecar to the exhaust mount under the engine that acts as a front stabiliser/sway bar - I know its far from an idea connection point as the engine is floating on rubber mounts but its better than nothing!

Welcome. Will always have a soft spot for MZ, having owned a solo, plus a factory produced sidecar outfit.

Enjoy.

Christ that's ugly!

Congratulations. :)

We need more Brits on here, the colonial types think they are in control.

Thanks for the comments, next mod im thinking some bolt-on LL forks based on the ones in this pic:
http://upload.wikimedia.org/wikipedi.../MZ-Diesel.jpg
Might happen in the next few months... hopefully....
Problem is im pretty rubbish when it comes to accuracy and to get within
5mm would be a real acheivement for me!

I can't understand Brit speak was that a resounding Yes or extreme sarcasm??

no sarcasm here, although, come to think of it...

oh - and wider handlebars would make a big difference, too.

Haha yeah it'll totaly transform it alright - wether i just plough into the side of a parked car or not will be more luck than judgement me thinks.....
But if i can keep things close to parallel it should be an upgrade to the low speed head wobble i sometimes get, i was thinking of putting a damper on it but i may aswell try and make some forks that do the job properly, winters coming and last year a bit of wobble nearly caught me out at 15 mph on a slippery adverse camber whilst following some nervous tin can driver.... Only get it between 15 and 20 which makes riding around town in traffic even more unpleasant.
