The Ninja 650 starts at $8,499, compared to $9,399 for the ZX-4R and $9,899 for the ZX-4RR. The ZX-4R strips back ZX-4RR features like adjustable suspension and color choice, plus it removes the bidirectional quickshifter. Outside of that, the two bikes are largely the same, including the engine.
The Ninja 650 is an impressive option and is arguably Kawasaki’s most reliable bike. The ZX-4R is great for people looking for pocket-rocket aesthetics and track-day thrills. Neither option is among the fastest bikes Kawasaki has ever built, but they still pack a punch. As you’d expect, the 650cc unit boasts significantly more torque than the 400 – even in its full-fat form — with 47.2 ft-lb compared to 29 ft-lb.
The Ninja 650 is the heavier of the bikes, but it packs a nice blend of everyday use and sportiness — something that helps make it a solid motorcycle for seasoned riders. If you want to unleash the full power of Kawasaki’s 400 screamer, you can flash the engine control unit (ECU) for about $250. But don’t expect Kawasaki to honor your warranty if you go that route. The included warranty covers your bike for 12 months, so it’s better to consider the change once that time has passed. On top of that, many states have noise regulations for motorcycles, and flashing your ECU could result in you exceeding them if you’re not careful. Be aware that modding your bike in this way is likely to increase or invalidate your insurance.
