People in the XC threads start discussing about the Husquarna TR650 which is in the same weight range and has basically the same engine as the XC. As the others it's missing a luggage system and a big tank. I guess the main drawback is the lack of aftermarket parts.
For me, the small tenere is the best off-the-shelf adventure bike on the market, if you don't want a heavy bike. Lots of small things like the replaceable crash pads, the strong subframe, the GPS bar above the instrument cluster show that people have thought it through.
