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.
It is less $ to do the dealer events you get a better group to view your products and make more converts that will drink the Koolaid than you do with the shows. In the calif central valley the attendance has dropped by nearly half of what attendance was 5 years ago.
in 2004 I saw the Thruxton at the NYC show. I bought one. I also saw the Daytona 675 there, bought 2. then the street triple, bought it. the 1050 Speed triple, bought it. the Tiger 800, yup bought it. last year I saw the new Thruxton and I bought one. so the bike show has been profitable for Triumph just from me. I'm still going tomorrow
I don't believe Triumph has had a presence at the big shows for a long time. As a regular attendee of big trade shows myself, both the public and "trade only" variety, I understand the reluctance to shell out the kind of cash those events require.
