Well as long as they were registered in the UK, surely/maybe they may count as well?

We most of mine were registered in Australia. When I moved to Italy I sold or gave to relatives 14 motorcycles.
This thread made me start to think about how many bikes I have owned.
Starting at 12 years old this is the list as far as I can remember. I am sure one or two are missing from the list. The first 3 (given to me by neighbours) and the Jawa bush basher I never used on the road. All the rest were used on the road (and in some cases track days). Except for a brief period I nearly always owned more than one bike. I still own the last 2 but I have not ridden a bike for about 5 years.
