I've been riding a 2008 R1200GS for the past six years, and for the most part, it is a terrific bike. Although mine was lowered at the factory, its seat is still higher than I would prefer. And then there is how the GS looks. It's grown on me, but I wanted something with more traditional aesthetics.
So, the Triumph has a lower seat and the bike is, IMO, much more attractive. It is also quicker, and possibly smoother, than my BMW. However, it does not seem to be as well-designed as a BMW. The BMW's brakes are far better (and linked). The suspension is probably comparable, but to minimize front-end dive, the forks are less supple than those on a tele-lever bike.
The Triumph appears to be put together with an attention to detail that previously eluded Triumph. I hope that its finish will hold up as well as that of my GS.
Because the Thruxton uses inner-tubes, I will most likely get the rims sealed so that I can lose the tubes. Today, I removed the rear wheel just to see how much work was involved. Not a good time. A Street Twin uses tubeless tires and can be ordered with a center-stand; things I would want.
In terms of engineering and "feel", I suppose that I would describe my Thruxton as somewhere between a BMW and a Sportster, but more toward the BMW end of the spectrum. It is very much fun to ride.
Ask me again in a year or two.
