And while the 399cc DOHC parallel-twin is fantastic—offering a broad, smooth torque curve and 43 rear-wheel hp on the Cycle World dyno—it is the Kawasaki Ninja 400's overall balance and high level of performance that put it at the top. Its more robust chassis and excellent suspension, plus well-thought-out ergonomics, make it a more flexible streetbike. It's a killer daily rider. But the biggest surprise was hitting the racetrack, where the now-littlest Ninja shined, belying the $5,299 price of our ABS-equipped test bike ($4,999 for non-ABS). The Ninja 400 truly rips and its budget-conscious suspension does an amazing job of keeping the bike stuck to the track.
