Special Category for British Motorcycles
[edit]As part of the Motorcycling WikProject I am working though all the missing articles and stubs for British Bikes. To make things easier to sort out there is a special Category:British motorcycles Please add to any British motorcycle pages you find or create. It will also help to keep things organised if you use the Template:Infobox Motorcycle or add it where it is missing. I've linked the Category to the Commons Motorcycles of Britain so you could help with matching pics to articles or adding the missing images to the Commons. The people behind the bikes also bring it all to life - I've created the Category:British motorcycle pioneers so please have a look and see if you can add or expand any? Thanks Thruxton (talk) 20:23, 19 January 2009 (UTC)
