Once again, BMW's R1200GS Adventure is the only reason you need to chase the sunset across a half-dozen continents--Antarctica may be a bit chilly--on any sort of road or no road at all. There are faster sportbikes, more comfortable touring mounts and easier ways to get across town, but nobody builds a better ride for taking the long way. Strap on the gear, cue up the GPS and go. Then BMW upped the ante for '08 with more power, electronic suspension adjustment and a nifty traction-control system that makes putting all that power down on some shale-strewn fire road a whole lot easier at the end of an 18-hour day. You'll pay $16,350 for the privilege, $1040 for the ESA and another $365 for the TC. With the optional saddlebags, tax, license and maybe a GPS receiver on the handlebars, you're on the wrong side of $20,000. Cheap? No. The best? No doubt.
