1960 - 1965 Junak M10[edit | edit source]
In the sixty's the Junak got a few variations - a sidecar, a load crate, a cross version - and had a serious facelift. The headlight got a smooth casing, which was integrated with the suspension fork, got a deeper mudguard, more efficient brakes were introduced, the chain was encapsulated and the exhaust changed. In the beginning it was supposed to be a heavy motorcycle - mainly for the military - with a 500 cm3 engine, but the project was changed and in effect a 350 cm3 class vehicle was created.
