This was posted up in another forum I'm in. Didn't know garages existed were all tools are provided and expert advice is on hand, you just do the actual work yourself. Really handy if you do not have the space or tools. Oval Motorcycle Centre
I know two who have used it and they loved it. And it's right beside Lambeth College which has motorcycle mechanic courses if memory serves. Though 'Oval' is pushing it a touch. Nine Elms or Stockwell would be closer to the mark.
The reviewed one of these on 5th gear a while back, good idea but they did things like changing brakes on a car but by the time you payed your money for renting the space you may as well of payed the labour and not got dirty! Good if you are in the situation I was in until recently where I did not trust any of the local mechanics with my bike
