Kawasaki Ninja 650

Kawasaki made some substantial changes for 2008/9 designed to improve rider comfort, enhance handling and modernize the look of the bike. Engine performance was not overlooked, either. Fuel injection is revised to improve throttle response and mid-range power, while cooling capacity was increased. The entirely new frame has a revised rigidity balance to enhance performance, as well as additional rubber mounts for the engine to decrease vibration. All-in-all, more than 40 "updates and refinements" can be found in the 2009 Ninja 650R. H

More than a pretty face with a good personality, this is a true Ninja sportbike

The Kawasaki Ninja® 650R already epitomized the ideal marriage of sportbike performance and relaxed comfort. For 2009 Kawasaki improved on this combination and gave this popular model several new upgrades, from improved suspension to updated Ninja supersport styling. The end result of over 40 updates and refinements, the new sportier Ninja 650R delivers serious performance fun and maximum transportation practicality.

The key to the Ninja 650R’s slender size is its compact liquid-cooled, fuel-injected, DOHC, 8-valve 649cc parallel twin engine, which permits the use of a narrow, lightweight frame. Revised fuel injection settings on this torquey engine boost its bottom-end torque, smooth low-mid rpm response and allow it to rev more quickly.

Routing the coolant to the cylinder and head through the engine cases reduces the number of external hoses. The engine also meets stringent Euro-III emission regulations thanks to its precise fuel-injection and a three-way catalyzer system with a new 300-cell catalyzer that’s smaller and lighter than the previous 200-cell unit.

The non-intimidating twin-cylinder appeals to new riders, and has an excellent mid-range that offers enough pizzazz to thrill more advanced riders. A modified shift lever position permits easier application of the Ninja 650R’s linear power delivery. The manageable power delivery and superb roll-on response enable the new Ninja 650R to make short work of the morning commute or perform as an entertaining track day companion – all while delivering good fuel economy.
 
This spunky sportbike received several changes to the frame, swingarm and suspension that result in reduced vibration and lighter handling, making the new Ninja 650R more nimble and comfortable than ever. Its signature trellis frame and offset laydown rear shock design remains, but the frame was completely revamped and now sports a higher quality paint finish.

The slim, compact trellis style chassis received more than cosmetic changes. Revisions to rigidity balance and suspension settings, and the addition of rubber upper-rear engine and handlebar mounts result in reduced vibration and lighter handling, enabling an improvement on the Ninja 650R’s comfort and handling.

Rider and passenger footpegs are now rubber coated to further reduce the amount of vibration transferred to the rider. The natural riding position and ergonomics are enhanced by a new slimmer and lower seat, which makes reaching the ground even easier than on the previous model.

Surrounding the Ninja 650R’s updated chassis is unquestionably sportier styling. From the wider windscreen and dual headlights to the high-quality finish of the sleek minimalist fairings and covers leave little doubt about this Ninja’s supersport genetics.

Avoiding unnecessary design flourishes, the Ninja 650R’s new sharper lines flow throughout the bike, giving it an aggressive appearance. Even with a new, taller fuel tank, the new fairing with integrated turn signals and a sharp tail cowl ably highlight this motorcycle’s compact dimensions.

Beyond its exciting appearance, new MotoGP inspired multi-function instrumentation and revised controls, the Ninja 650R is rolling proof that a performance motorcycle can be practical and comfortable. The rider may notice the slimness of the chassis, low seat height and minimal effort controls first before realizing the true aim of Kawasaki’s design efforts – the rider.

The Ninja 650R’s friendly ergonomics provide a versatile cockpit that both novice and experienced riders will use to employ its assets to the fullest, from the daily commute to a weekend canyon run. In other words, this real world overachiever easily demonstrates its versatility and everyday usefulness

Sleek New Supersport Bodywork
- New dual headlight design features multi-reflector bulb hoods and the twin position lights – like its Ninja supersport brethren
- Rider comfort is improved via a lip at the top of the revised windscreen, which helps deflect air away from the rider, along with a duct in the center of the cowling that creates an “air curtain” to reduce wind buffeting at higher speeds
- New, taller fuel tank – especially noticeable when viewed from the side –adds to the bike’s crouching appearance and allows fuel capacity to remain the same despite adding a fuel level sensor – for the new fuel gauge
- A flush-surface fuel cap and its sharp-edged motif give the new tank a distinctive new look
- Sharper, edged lines give the Ninja 650R a more aggressive, crouching supersport look, yet the bodywork still accentuates the frame
