The Kawasaki Ninja 650R is engineered to deliver the best of performance and accommodations in day by day riding as sportbike performance levels and a comfortable seating position are basic features of this interesting-balanced motorcycle.
Kawasaki designed the Ninja 650R with versatility in mind, resulting into a bike that invites to be ridden daily. Blending an innovative engine and chassis when willing to create a sportbike is always a good idea and the bike obtained will definitely achieve the points previously established for the sales evolution. But when a bike outruns any expectation that is when you know that you’ve done a good job. This is also the case with the subject of this review.
Like all Kawasaki’s sportbikes, the Ninja 650R, even though was introduced very recently, has behind a model which lead to its creation. In this case is the ER-6n, a motorcycle launched at the end of 2005.
It planned on conquering the mountain named success by using a low center of gravity which results into a great handling motorcycle. In communion with a decent power output, this model formed the base of the Ninja 650R, a motorcycle launched a year later.
The idea was to create this Ninja by simply attaching a fairing with the purpose of obtaining less drag and better wind protection for the rider. Afterwards, by painting it in a two-tone color (Black and Silver), the exterior was radically changed and it was ready to shine.
Also characteristic to Kawasaki motorcycles in this lineup is the user-friendly behavior coming from a two-cylinder engine which is actually smaller than the one found on the Ninja 500R.
With the 2006 Ninja 650R, Kawasaki proved it can take an already successful product even further by simply adding all those attractive elements that make it a Ninja. More important, the riding feel speaks for itself.
The middleweight sportbike class is one very disputed and manages to gather most of the Japanese manufacturer for a piece of the cake.
Yamaha, of course, offers the FZ6, an awesome performer thanks to its 600cc liquid-cooled inline four-cylinder; DOHC, 16 valves engine. It says a lot more than the Ninja but they are both multipurpose, go-anywhere, do-anything middleweight motorcycles and implicit, are meant to do pretty much the same things.
Another example would be the Suzuki SV650SF. This motorcycle offers its own kind of middleweight agility combined with V-twin power. The engine configuration allows for great amounts of torque delivered from down low and the fuel injection tops the levels of performance.
But middleweights are built to handle and the Suzuki does it like a dream due to its aluminum-alloy truss frame and technically advanced suspension front and rear.
You would expect to find the Honda 599 offering refinement and sharp handling, but this model is out of the battle as Honda decided to retract it from the U.S. market. It was a blast, by the way, so I don’t understand the reason…maybe a surprise is awaiting.
Even so, the Hornet 600 is Honda’s alternative to comfort and sporty abilities.
Maybe the competition does a better job with different engine types but it is no doubt that Kawasaki rules when it comes to styling. No matter the color (Green, Red or Black) this one is a turn header.
The biggest advantage is that it doesn’t sacrifice the riding position in order to achieve being a sporty looking motorcycle. No, its beauty consists in the fact that the low, narrow seat combine with slim overall design and it allows the rider to touch the pavement with confidence when stopping.
This bike was built to be a true friend on the roads so the manufacturer first considered the rider and created carefully designed ergonomics which present a comfortable, natural riding position.
If you take a look at the stylish full fairing featuring an aerodynamic windscreen, you will actually expect to be tired after a few hours on it, but this won’t become a reality. The visual impact is also upgraded by integrated front signals with clear lenses.
Personally I like it covered in Sunbeam Red paintjob, as it is kind of unique, and it matches the black colored rims, frame, swingarm, and pretty much everything that isn’t red.
Riding the Kawasaki Ninja 650R is easy and enjoyable for all kinds of riders, especially beginners. This is the result of a machine built starting with the rider. It may seem strange, but for this middleweight to be situated in the top concerning riding position and comfort, it had to be manufactured following such a strategy.
I was properly accommodated on this carefully engineered motorcycle and felt no disturbance whatsoever. I find the seat comfortable and its texture didn’t allow me to slip under powerful braking. Handlebars are at quick reach and the footpegs contribute to this ideal riding position found on the 650R.
The second high point of this Ninja is its responsive 650cc parallel twin-cylinder, DOHC engine fed through a fuel injection system. It enjoys being revved all the way through its powerband, with healthy torque starting with 2500rpm, but where this motor enjoys sitting is around 7500-8000rpm. Even though it can go easily up to 10,000rpm, I only took it there for few times because this is no race-inspired four-cylinder, but a permissive parallel twin which won’t surprise you by giving a rush between certain levels of its rev range. It is truly an awesome performer in the low and mid-range so it receives all my appreciation.
Mated to a six-speed tranny, the lively twin delivers linear power in every gear. I enjoyed exploiting the engine at its true value and it proved not to have any disappointment reasons. At around 80 mph, the crankshaft spins with 5000 revolutions per minute in top gear.
The counterbalancer incorporated does its job perfect because I didn’t detect any vibrations even if I was engaged in a highway passing or in an enthusiastic twist of the throttle. Also at relatively high speeds, wind protection is excellent thanks to the full fairing and the windscreen attached to it. I would compare a ride with the Kawasaki Ninja 650R as a trip on a middleweight cloud. It is that reassuring!
Being light, narrow, and allowing for a comfortable riding position, the Ninja 650R has pretty much what it takes to be true easy handler. It is almost too easy to be leaned in corners and it finds the way all by herself once you’ve seen how it likes to be treated (slower at the beginning of the corner and then accelerate progressively as you exit from it). Twisty roads are a true pleasure and this is also the kind of situation in which I appreciate being on a sharp handling motorcycle.
What I don’t find that confidence-providing is the front suspension system which felt a bit weak while cornering. But maybe that was just me fascinated by the looks of this bike and thinking that I’m on a ZX-R motorcycle. Better overall handling comes from the short, compact frame and engine design which allows the adding of a longer swingarm.
I appreciate the braking system though because it is ZX-R inspired and the brake discs feature triple petal design resulting in improved cooling and warp resistance. Braking power is more than sufficient and both the front and the rear receive the credit for that.
Overall, this is a recommended motorcycle for beginners and not only. It features predictable, linear power all the way through the powerband and everything is valued through a smooth operating gearbox. Already popular as a sharp handler, this Kawa sees its way through in a very competitive class.
The Ninja 650R is also a cheap solution for the already enormous number of cars on the streets today. Comfortable, permissive, versatile, and confidence-inspiring, this motorcycle asks for a try and a try only in order to convince you that the ride is well worth the buck. With an MSRP of $6,499, it is the cheapest bike in its class, not necessarily the one that has less to offer.
Kawasaki used the Ninja designation for the 650R, and it made no mistake as the bike features the sporty character you would encounter on such motorcycles.
By proving user-friendly, reliable and manageable under all riding conditions, this middleweight not only stands as an alternative for beginners, but presents a totally new side of the Ninja lineup.
