Ah,Yes ! Having worked on,ridden and rebuilt hundreds of the things....I do have bit of a soft spot for them.
At one time The Most Stolen Motorcycle !
First bike I rode....Tuned MZ ETS 250.......Speaks Volumes,I think !
Went on to own 1 Simson 50,3 TS125/150,1 ETZ 125/150,4 Supa 5,1 ETZ 125/250 Hybrid,and a 500 Saxon Fun,CZ 250,350,2 Jawa 350 one with a chair.
Favourite machines of mine ETZ 125/150,Supa 5,500 Fun and CZ 350 plus one or two others that I have owned.
Same sort of reasons
Cheap,reliable,robust and Bloody Good Fun.
