Royal Enfield

We are getting to see other parts of Redditch in our your of local Screwfix shops. Today we visited the Royal Enfield retail park and found this sign on the side of an old building.

I understand that a Royal Enfield Bike was a motorbike in continuous production for longer than any other bike. That's all I know so far except for the fact that they were built in Redditch. Lots to find out.
