2006 Kawasaki Ninja 650R

Unique look and feel grew from specific design team objectives seeking to blend attractiveness with power.

Look at Kawasaki’s all new NINJA® 650R sportbike and the first impression is one of pure design appreciation. Look a little longer and many of the innovative engine and chassis elements begin to come into play. But the entire package doesn’t truly project its intended engineering outcome until the motorcycle is viewed with a rider seemingly melded into its unique posture. Because the 650R was meant to have broad rider appeal, Kawasaki’s development team began its task with the rider-not the motorcycle.

Focusing on all kinds of riders, and all kinds of riding, Kawasaki carefully studied the interface between human and machine. Riding positions were studied to discover which instilled the most confidence. Narrowing the distance between foot pegs and striving for a lower seat height and low effort controls all played into the design efforts.

Ultimately, this exceptionally well-proportioned NINJA® 650R represents a genre of motorcycling new to Kawasaki- one that finds itself at home with both novices and experienced riders, and one that will be seen equally in daily midtown commuting situations as well as week-end highway getaways.

A combination of versatility, performance and style, this motorcycle knows no boundaries in terms of rider appeal. It will be a first-time purchase for some, a second or third motorcycle for others, and for all, it will be fun. Powered by a compact 2-cylinder engine mounted in a sleek, lightweight chassis, this extremely maneuverable model will earn its rank as on of the most rider friendly units in today’s marketplace.

The very compact liquid-cooled, DOHC, 8-valve 649 cc Parallel Twin with fuel injection delivers a smooth responsiveness that is tuned for rider-friendly power characteristics- especially in the low and medium rpm ranges that will inspire confidence in new motorcyclists. Its excellent mid-range characteristics will make the 650R a natural for medium speed commuting environments. And slipping in and out of traffic will be a cinch for this new entry, as its lightweight trellis frame and laydown shock also contribute to its overall compactness.

While the powerplant on this new NINJA® is compact, it is anything but minimal in its output. Just gauge the 650R’s roll-on response when making a highway pass and any concerns in that area quickly subside. The engineers called on their vast experience building NINJA® supersport machines to develop a motorcycle possessing performance characteristics that will be a match for anything currently available in the middleweight arena, including those with larger displacement.

Engine characteristics:

  • Triangular layout of the crankshaft and transmission shafts make the engine very short, front-to-back
  • The transmission’s input shaft, output shaft, and change drum are contained in a cassette-style package that both works for the 650R’s compact layout, and facilitates transmission maintenance
  • Engine height is reduced through the use of a semi-dry sump design
  • This new Kawasaki has a plated, liner-less aluminum cylinder which is lightweight; its narrow cylinder pitch reduces engine width
  • Under-engine muffler improves mass centralization and lowers the 650R center of gravity
  • Compact engine design allows use of a slim, minimalist frame, which results in a design that is narrow at the knees and feet
  • Light and nimble handling characteristics are one of the benefits of the extremely short wheelbase of this motorcycle
  • A long swingarm is used, so both rear suspension and handling are improved
  • Engineers used 3-D analysis to achieve the ideal stiffness balance for the frame, which contributes greatly to its handling characteristics
  • Frame construction is of high-tensile steel, rivaling the lightness of aluminum frames
  • The layout of the offset single-shock rear suspension allows the battery to be located next to the shock rather than beneath it—making for a slim design and lower seat height

Bringing the motorcycle to a stop is handled by triple petal disc brakes that look as good as they perform. And the attractive six-spoke supersport-style wheels give the 650R a “light” look while reducing unsprung weight.

This new entry sports a very aggressive headlight design, an aerodynamic windscreen and full fairing, and front turn signals integrated into the faring. The flowing bodywork includes a slim tail cowl with flush-surface tail lamp lens giving the new NINJA 650R a slim, agile appearance from the rear.

Also contributing to the slim design appearance is a two-tone seat and a sculpted fuel tank. Instrumentation abounds with this multi-purpose motorcycle. A compact step-motor speedometer features an LCD display with digital readouts for odometer, twin tripmeter, and clock as well as an LED water temperature warning lamp.

Few will look at or ride Kawasaki’s NINJA 650R and fail to come away impressed. Both from a design and a performance benchmark, the team responsible for this new motorcycle has accomplished their stated goal-creating a new category for Kawasaki where every rider, new, old, male, female, experienced or novice-can find a reason to park this one in the garage.

I have a 06 650r and love it. its comfortable and quick. I have the carbon fiber two bros. exhaust and it is roudy to say the least. I get a lot of people commenting on the bike wherever i go and the only people who dont like it are harley guys and guys who think that if you have anything less than a 1000 your a wimp. Overall i would say this is a great bike to learn on and to drive on a long trip where most other sport bikes would leave you cramped. If you ask me its definetly the best bang for the buck!

I have no riding experience other than the basic MSF course. Before that, I didn’t even know how to turn on a bike.
Well, I ended up getting an 2006 Kawa Ninja 650 for my first bike. I read a lot of reviews, on a lot of bikes, and I found this one at a good enough deal.
So, I bought it, and had to ride it home. After racking my nuts off the gas tank once, I cooted back a couple of inches, and never had a problem again.
Have now ridden 1,000 miles in 2 months. Its a good bike, but shifts (slides) over a notch in the sidewinds! :[ And I get bounced a little in the wind coming off the front. Other than that, its great. I’ve read several reviews, and everyone says how it is a great bike. Responsive, and good for both beginners and experienced riders. (Top speed of 128 mph, and 0-60 in about 3 seconds. I’ve done it.)

I plan on getting a double bubble windscreen for it. Others wise NOTHING to complain about. and as far as mufflers, its fine. Louder pipes I do not believe help. I have never sat in my car and heard a bike come up from behind. I never knew he was there until he came along side me. And you can get a ticket for having too loud of a muffler.

I have a 2006 650r and put a Leo Vance exhaust and Ermax undertail on it. Now my bike looks and sounds sweet!!!

i’ve got an 06’ 650r and love it. i’m a veteran rider and also have a lot of seat time on trail and motorcross bikes. these people that say the 650r is just for beginners are rediculous. although it is excellent for beginners ,any vet rider will love this bike!!!!!! due to the handling, throttle response, power, and looks it literally glues itself to the asphalt.....

I bought a Blue 2007 650r. I love the bike. The bike exceeds any expectations I had. I am a new rider though! This bike is great to learn on. It is very gentle upon pull out, but has alot of snot even in the low rpm range. I recommend this bike for experienced and unexperienced riders.

I just recently bought a ninja 650r and i enjoy it, it’s quick, fast and handle very well.

I’m concerned about the exhaust, it being under the bike does it sound loud enough? If not, know of any websites that have aftermarket exhaust, or any aftermarket parts for it for that matter

ahhhhhhhhh im bout to buy one

hey whats up people..im what you call i guess a noooby ...so woul the ninja 650r be a good beginer bike? ive ridden just a couple of times on a 636 but not too expirience and its time for me to start..thanx

I just bought a 2007 650R. It seems extremely fast to me. Is this just because I’m a new rider? I was riding recently with a bunch of guys on more powerful 600 class four cylinder bikes and kept up fine with the accelleration up to about 100mph, then accelleration seemed to drop off, (I may have let off the throttle subconciously, not sure).

hey 0 to 60 in 3.4 seconds on a 2007 ninja 650r i own one and i timed myself that aint to bad’ i actually love the bike i have a 06 636 also and the 650r is way more better to ride in the city and on the highway’

I agree wear the right gear.
About the riding with OLD VETs. Why not.
You can learn alot. I been riding for about ,25 years.
I have a Concour now. Its not super fast but fast enough for me.
My Son is comming back form Iraq soon he wants a bike.He rode dirt bikes befor but not a sport bike.
I was looking at the 650 Kaw. For him; Fast enough,for a 20 year old kid. My older kid has a 636Ninja. I think it will be a good starter bike.
Looks great and from Comment #4 sounds like he knows what he is saying.He is about 5,9 170 pounds.
I think it will be a good starter bike.
Things Vet riders will tell you.
DONT BUY A BLACK BIKE BLACK HELMET BLACK JACKET. I did that once,it all was great and mean looking,but the lady in the car never spotted me.

1st comment: Please. Just because you like a little throttle to test the range doesn’t make you a squid. I ride an 04 R1 and push it to the limit, but not too often on the highways, wear the proper gear, so don’t be stupid. Why don’t you go and ride with your old "veteran" (learn how to spell) riders with a 250 between your legs and enjoy the scenery.
2nd Comment: For a beginner, I agree..they want the look and a little bit of umph..this is for you. If the liter bikes are more your style, this bike WILL bore you.
3rd Comment: Actually, not too top heavy. Gf got one, new rider, I took it out for a spin and I was pleasantly surprised. No, not something I would want, but perfect for the novice as well as the seasoned, more conservative rider appreciating looks and style.
02 F4I
04 R1

1: spell check before you publish, it is kinds not kids of riders.

2. It still does 0-60 faster then most car son the road, you don’t need a liter bike to go fast. If your idea of going fast is grabbing a handful of throttle while going in a straight line, you are a squid. I’ve known many of vetran racers who have a blast on little 250CC race bikes with less then 50hp.

Weighs more than a gixxer1000 with half the horsepower cant be that much fun—style only goes so far

LoL looks like a KLR with street tires and fairings—bet its top heavy for a smaller bike huh?
