The more I think about this the more I think Triumph's going to do something unique with the 2300 triple.
It's reputed that Triumph has 12 new models coming out over the next two years. Where Triumph is unsuccessful is where they enter into markets with a clear and distinct segment leader. Look at the Trophy 1200 Sport-tourer; sales have been very poor - Triumph is butting heads with the BMW R1200 and 1300 GTs and not getting the better of it. Same with the Tiger 1200 Explorer; sales are a little better, but nothing like what BMW is doing with the 1200/1300. especially now with water cooling on the BMW's. So I think it's unlikely that they're going to do a Goldwing or K1600 GTL competitor with the 2300.
On the other hand, where they have GREAT success is where they set the standard in the segment (like the Daytona 675, which has been universally praised by everyone who has tested it as the BEST sportbike in its segment); or the Speed Triple or Street Triple, which everyone agrees are unique; class-setting rides; or the Bonnies, which are the most successful of the retro classics being sold by any manufacturer.
So I think that if Triumph is going to seriously penetrate the touring market - they're going to do it with a unique tourer based on the 2300 triple. I'm not smart enough to know how or what, but I think they'll tune it more along the lines of the Roadster tune and make it a truly high-performance touring bike. I think the only thing near it's class will be the K1600 GTL - but I think that Triumph is going to try hard to distinguish any high-performance tourer from that bike - rather than compete with it. Weight will be an issue with the 2300 and I don't know how they will get around that. Maybe something along the lines of the Victory Vision, but with less controversial styling and higher performance.
Anyway, I don't think they're going to abandon the 2300 - at least I sure hope not. I think it's one of the great engines motorcycling has produced - the kind of thing that 100 years from now, they'll talk about like they talk about the Curtiss 8s from 1908, the Ariel Square Four and the old Indian fours.
Just my opinion.
