Since you are not going off road and you want sporty-naked, then I would suggest the Pocket-Rocket. I have one and it is as fast and sporty as anybody could want. I've done one century and several metric centuries.
Bike-Friday's customer support is first class, even in Europe. You need to contact them to find where you can go for a test ride. Quality is such that you should not need much in the way of support. In addition I would stick to standard bike components and stay away from stuff like the Sachs 3X8 hubs, which seem to need more care. Using standard components like rear and front dérailleurs makes your bike easier to maintain and parts easier to find locally.
Good luck at what ever you choose.
