A truly magnificent piece of British motorcycle engineering.
As a kid I would often be taken to the local gravel pit with my dad & ride all over the huge mountains of excavated gravel .
We used to ride. Grandfathers old BSA bantem , I'm not too sure which model it was but I do know it had a single rigid seat.
It was great fun but sadly my dad sold the bike way back in the late 60,s .
I wished we still had that bike now .
I often take a look at some of the wonderful old brochures that were made for motorcycles back then .
