I wonder if their marketing department feels there's more impact from those "Live" events they have been hosting in specific Triumph dealerships in the US. The IMS shows no longer stop in Seattle...used to love going to those.
My personal experience has been that my wrenching skills usually leave things in worse shape, so I end up supporting those who are much better at it than me, which is probably for the best.
I don't know if this is what you are experiencing, but my 2013 Speedmaster would very occasionally die when starting from a stop, say at a stop light. The dealer adjusted the throttle bodies and upped the idle (looks like just below 1100 rpms), and the problem has gone away.
