Can anyone help with any knowledge of a strange old ‘bitsa’, trials motorbike I’m playing with?
It’s registered as a DMW and the square section frame would suggest that it started out as one.
The back end has been modified to support a Royal Enfield swinging arm and wheel. It’s thought the frame may have originally had a solid or plunger rear end. It’s got two rear sprockets bolted together, but I can’t see the point as it would be impossible to run a chain on the smaller due to it being against the larger.
The front also has Royal Enfield forks and wheel.
The engine’s a pre ’63 Tiger cub unit.
The petrol tank’s probably also from an Enfield, but it’s been cut and welded and a separate oil tank formed at the back end. Most DMWs were 2-stroke if I recall correctly.
There’s a natty little chain oiler using one of the rear frame sections.
The registration is, I believe, Carlisle, although I was told it came from Newcastle.
Someone’s obviously spent a tremendous amount of time and effort in putting it together and I’m wondering if it’s got an interesting history.

You have correctly identified the major components of this machine.

If you want to recreate this DMW as it left the factory it would involve different forks.wheels,petrol tank and engine and frame modifications to return it to plunger rear suspension.-The bike would then have a similar appearance to the machines owned by the Price brothers.who were talented and skilful trials riders.I have recently created a similar bike an HJH made in Wales with major components from DMW, unfortunately these bikes have no place in the current classic trials scene- trust me I have tried!!

Bottom line enjoy it as it is!
