2016 BMW S1000RR LOW MILES

A 2016 S1000RR with 4k miles and a factory-fresh Akrapovič setup is basically a time capsule—most of these were either thrashed on track or parted out by now. At $17k, you're getting a superbike that still has its entire lifecycle ahead of it, which means resale legs most used sportbikes simply don't have.
