Welcome to The Shed. Here you will find a wealth of information about pre WW2 Motorcycles and maybe a few street custom machines too. This is the place to share information about your restorations as well as learn more about our projects. We are also building a virtual museum where you can learn more about British Motorcycles.

I have recently been documenting the rebuild of Brooklands Museum's ABC. The motorcycle is a 1921 398cc ABC designed by Granville Bradshaw. It is somewhat unique in its design having front and rear leaf springs and horizontally 0pposed cylinders, reputedly later copied by BMW.
These Gearboxes originally specified a first fill of 800g of grease or a Grease/Oil mix.
We supply a Semi-Fluid Grease which does not separate in use. This is not available by post, but is on our stall at Kempton & Ardingly.
This film shows the stages of stripping a Burman CP Gearbox, but you may need to turn down the sound as there is no commentry. We would advise taking it slowly and gloves are always a good idea
This film shows the reasembly of the CP Gearbox and does have commentry up to inserting the gears then tails off !. I was once told by a very wise man, that you seldom assemble a Burman gearbox once during a resto. What we like about this film is it doesent just skip over the challenging bits.
An amazing film of a Magneto Resto/Rebuild.
