Generally speaking I don't see Triumph on the road. Maybe 3-4 at weekly bike night where they have about 300 bikes on a good night. I saw 1 Tbrd in the last year outside of a showroom. Have not seen the 1700 at all.
No, Triumph does not release the numbers built on any models. They really don't release the numbers built total either. They just leak unverified stuff to a blogger who will write something about it.
