Motorrad Central in north Glasgow. It's a bit of trek from Doncaster so you get to have a decent ride out on the way. Then, after you've helped youself to their free coffee and got your bike back you can road test it over some truly sublime Scottish roads before riding back home to Doncaster.
Surely this is a win win situation
As I live in Glasgow I've just realised that I need an excellent dealer somewhere in the French Alps
