They look sharp, although likely will be heckled for being somewhat underpowered in a market full of 100+ hp behemoths. These would probably be a load of fun and perform reasonably in urban environments. Cost factor is likely in their favor as well, the best part, it is not likely you will blow large amounts of $$$$ on accessories and thus may just spend more time riding, probably the greatest aspect....
I've been looking at these wondering the same as you, it seems retro is back with the Norton Commando and other similar bikes being marketed...
One other note, although the engine does not produce a massive amount of power, being relatively understressed, is probably quite reliable...
Oh, and almost forgot,
