Friday bike

Another one you've probably never heard of.

1970 Balkan MK50 2JU25


Found mention of this in an article and as I'd never heard of this bike before, decided to do some digging.


Balkan were a Bulgarian manufacturer who built a range of two stroke bikes from 50 to 250cc. Virtually unknown outside of Bulgaria, they ceased production in 1975. This particular model was labelled as 1970, and I found a photo of what looks like an earlier version.
