I had planned to take my kids to the Birmingham zoo today, but it was rainy. Instead we went to Barbers. The kids enjoyed it better than a zoo. There are probably 600 bikes there. But I didn't see an XS400.
I think I saw two XS models. One was a single cylinder Exciter, with styling nearly identical to my 83 XS400. The other was a 500cc special that looked like a 79ish XS400.
The coolest thing I learned is that triumph and Harley 1950 models looked just like today's cruisers. They really were amazing looking bikes for their day.
