MZ ETZ 250 — Part One

Rick was looking for cheap thrills to on long distance trials. A MZ and the motorcycling club fit the bill.

The MZ ETZ 250 me Ј250. If it wasn’t being by a friend I might have to beat the price down to but it had some MOT and road tax, so we both fairly happy the figure. I saw it as a potential long trialler as there is a small of dedicated MZ riders in the long trials world.


had used it as a commuter, and the road commuter to long-distance trialler is a rutted, slippery one! The MZ sat on the side of the road outside his unloved, gently rusting in the Plymouth air, and a bit sad. We about how he expected one morning to other run-down MZs, CZs and parked alongside — an temporary recycling point for eastern European bikes.

At first inspection the quirky German machine is, well, The spine frame makes the mounted engine protrude the breeze in a slightly unnatural but there’s quite a lot of important clearance. The rubber mounts rid the of lots of unwanted vibes as the is freely revving, being (64mm … x 69 bore) and comp ratio.

The long is efficient and kills the raucous tak-tak-tak to a more acceptable like it or not, more and events are looking at acceptable limits.

On this model are standard 18 alloy rims and back, later ones a 17 rim and a shorter wheelbase / swinging an effective but not startling 160mm over 6) diameter rear brake, and a pretty reasonable (just over 8) front brake — though earlier ETZ models were with a drum brake isn’t so good.

The forks are Ceriani copies and well, the lower yoke is the upper aluminium alloy a material used throughout the — on which are mounted showing mph and revs plus basic … lights and the switch. Handlebars are narrow, alloy levers, with the choke lever ever The throttle has twin cables one each for the carb and oil pump.

The fuel tank holds 4 gallons in total (including a 1.5 reserve which really to about 15 miles) — quite thirsty. The tank limits the steering lock to and replacing with an earlier TS helps here. On green and MCC events I haven’t yet found the wanting, although stepping off a bike and onto the MZ takes a or two to adapt to the limits.


The is a BVF 30N 3-1 — a basic model originally on a Bing and allegedly not to mess with, but replaceable a 30mm Mikuni. It’s on a lengthy inlet tract, and to a rubber shroud and sizeable air and system which reduce noise considerably. The air filter is within the LH alloy side under which is the separate 1.3 tank for 2-… oil feeding a autolube pump.

The phase generator is rated at an 210 watts and drives the standard car H4 55/60W headlamp with All the electrics look as if they’re to last, and from an earlier — 1950 perhaps apart from the sticky-out and large rear light separate rear and stop

But it works, and works well. headlight is a dazzler — what you need to avoid the and rocks about to cost you gold medal!

Long Distance Trials

MZ ETZ 250

one of the oldest forms of motorsport. 100 years ago, a bunch of of the new powered bicycles formed a and then set a test — a big The Motor Cycling Club was in 1901, and by 1904 had devised an test of the fledgling machines — a run from London to non — stop, in a set time and on a prescribed route.

The riders the trial successfully in all respects awarded a Gold medal for efforts. The … was cast on an that has ever since held annually, and became so that two other events devised to further test the of those Edwardian pioneers the Land’s End trial (1908) and the trial (1910).

All three run each year, with the taking place in the depths of on the 1st or 2nd weekend of January; the longest, the End, starting on Good and finishing on Easter Saturday in the of Cornwall; and finally the shortest but potentially the toughest, The Edinburgh, on the first weekend of October Tamworth to Buxton.


Once upon a the only way to take part was to be by ‘the committee’. Run on quasi-military the MCC trials, and the Brooklands speed run by the MCC were considered a pinnacle of and motorcycling skill and manufacturer’s with well-known names for honours against private

Today entry is easier and to any rider or driver who holds an UK or European Driving Licence, a competition licence (ACU licence for bikes) and MCC or VMCC or membership. The entry system has been developed for on-line which makes the whole even more straightforward.

New and potential entrants are directed by the to contact experienced MCC members to advice on class, machine and generally what to expect; how to in entry forms and get hold of ACU etc. The MCC website has a great of information including entry giving potential entrants’ an of what type of machines are and in which class.
