Kawasaki Ninja ZX 14

The 2009 Kawasaki Ninja ZX 14 has not rested on its laurels. The winning traits – massive torque, effortless power, agile handling and comfortable ergonomics – of the 1352cc Ninja king have landed it a sizeable collection of open class sportbike victories. Despite ever-tightening noise and emissions regulations; the ZX-14 has continued to set the pace of sportbike excellence ever since its domineering debut in March of 2006.

No doubt about it, the ZX-14 is a testament to effective evolution. Its engine and exhaust system permit it to comply with strict Euro-III emissions and tightening noise regulations.

Aprilia RXV 5.5

This lightweight bike's knobby tires and floaty suspension are difficult to manage on the road, but a dream in the dirt. It takes serious discipline not to power slide the rear end in the dirt at low speeds, but when you've gathered enough velocity and need that extra bit of power to get you up a hill or out of a rut, the RXV always delivers. Equally unflappable is the suspension, which offers enough cushion for large surface irregularities and jumps. Ergonomics-wise, the RXV 5.5 is as intensely focused as its powerful engine; the narrow seat is a stratospheric 39.2 inches tall, and the rider's forward position puts the onus on precision, as the rear brake and the 5-speed shifter is a foot's twitch away.

Overall, the Aprilia RXV 5.5 is a tremendously capable offroad bike, and no doubt a handful for most riders.
