I'm just about to put in Wayne's map for standard Tourings with no other work done and that will reportedly get me past 110 real-world horses. That's plenty for any conceivable road-riding purpose when combined with the torque of the Touring, so which you get isn't really so much about the power but about the looks and the entire purpose. I don't regret getting the Touring, even untouched it is scary fast 0-60 if you short-shift your way there and use the low-down grunt, and the hard panniers and the 180 rear makes it turn absolutely beautifully even in the twisties for a bike its size. A 240 tractor tire back there comes with some drawbacks, and you don't really need 240 just to get grip to accelerate - though it looks awesome, admittedly.
That said, and for the purposes of the original question, I'd rather buy a Roadster from a local dealer than go through the hassle of shipping a bike halfway around the world from the US. The Touring is nicer (in my opinion) but not that much nicer.
