The 600 class is right where a lot of savvy sportbike riders land. Why? Six hundreds—especially inline fours like the CBR650R—just strike a near magical balance between power, weight, maneuverability and the human scale. And when you’re looking at a CBR650R, you’re also looking at a bike with a wide performance envelope, able to hold its own in the canyons and still practical enough for leisurely weekend rides or daily commutes. But if there’s one thing that really sets the CBR650R apart, it’s this bike’s engine. Nothing revs like an inline four, and nothing’s as smooth either.
