Whoops...guilty, I'm afraid, of bringing my work home with me. I'm paid to correct things like that and once you get into the habit...well, you can guess the rest. Also I'm just one of those people that hoovers up trivia, which is at least good for pub quizes.
Can't be all that clever cos I ain't rich
I had two MZs...a 125 that I took my test on, basically an East German Bantam, and then a 150 I bought some years later as a runaround. Nice little runners, but they had seats like planks and numb bum would set in after half an hour. Front brake left a bit to be desired too...the old joke was that when the instructor told you to plan your braking ahead, MZ riders would check against the calendar!
The standard mod was to swap the front hub and brake for a Honda unit, though I never got round to it myself. Western tyres helped a lot too - the originals were, I think, Barums with a very hard compound that lasted for ever but could get, er, interesting in the wet.
Sometimes I think I wouldn't mind one now as a knockabout bike despite its faults, but ebay prices are getting a bit silly.
