The BMW K1200RS isn’t just the summer’s best motorcycle—it’s the best motorcycle I’ve ever thrown a leg over. Remarkably versatile, the bike makes short hops around town comfortably, handles curvy back roads nimbly, and hungrily eats up highway miles. But the open road is where things really get interesting. The K12 ($16,990) is so smooth, solid, and vibration-free, I found myself humming along the banks of the Delaware thinking I was doing about 75, when I glanced at the speedometer and realized I was running at Autobahn speeds. At 600-plus pounds, the bike can feel a little heavy during slow-speed maneuvering, which means you have to pay attention when doing things like rolling it in and out of the garage. Don’t worry, you won’t have to go slow for long. The K12 covers 0-to-60 in less than three and a half seconds.
