The Kawasaki Ninja 650R is the U.S.-market, faired version of the motorcycle ER-6n, known as the ER-6f elsewhere in the world, introduced in 2006. The 650R is a middleweight twin motorcycle, designed for normal use on paved roads. It has modern styling and features, with low-seating ergonomics, a low center of gravity, and respectable, manageable power output, and has proven to be enough bike to keep seasoned riders entertained. The design of the bike is meant to maximize rider comfort and integration, and be aesthetically equivalent to larger, more powerful superbikes.

The 650R/faired ER-6, known as the ER-6f overseas, was introduced to the market in 2006 by Kawasaki Motorcycles. The unfaired ER-6n is not sold in the U.S. The 2008 650R has an MSRP of $6,499 USD, $200 more than the 2006 model. The motorcycle fits above the Ninja 250R & Ninja 500R models which were already present in Kawasaki's sportbike lineup, which includes the famous Ninja ZX models. 2006 U.S. models came in two color options; black upper with silver bottom, and silver upper with black bottom. The 2008 models are available in Sunbeam Red, Lime Green, and Metallic Diablo Black, in single-tone treatment.

[edit] Common Complaints

The 650R or ER-6F was released shortly after the original "naked version" and the full fairing was added on directly to this original design. Unfortunately, vibrations from the running engine causes a problem commonly referred to as "fairing buzz". A buzzing noise from the front fairing is most notable in the low- to mid-range of the engine when vibrations are strongest. Reports of this problem isolate the source as near the upper left fairing, but this problem is not limited to only that location. The buzz has also been found to be a loose windshield, this has been corrected by simply tightening the screws on the front. Improvised custom solutions for this problem include rubber washers, electrical tape, and weather stripping; however, a fix covered under warranty was later provided by Kawasaki first in the USA, then later in other countries such as Canada, the UK, and Australia.

Many owners did not receive "helmet tethers" (used to secure helmets to the bike when not riding). In most cases Kawasaki shipped the cables to owners free of charge, because installation is easy enough for individuals to do themselves.

For some owners the mirror stalks are not long enough and, as a result, do not allow for a full view to objects (including cars) directly behind the rider.

The handlebars remained unchanged from the original ER-6N design, which are more suited to more traditional "roadster" style motorcycles and offer a fairly unagressive, almost upright riding position. With the Ninja 650r aimed at being more of a sports bike rather than a middleweight tourer, the riding position feels inappropriate to some, although the handlebars and their mounting are a standard type and can easily be replaced with after-market parts.

[edit] European Version

ER-6n, the European naked version

In Europe the bike is sold as the ER-6f or faired version of the ER-6, the "naked" roadster version is sold as the ER-6n. The ER-6f differed slightly from the Ninja 650R as it featured the passenger handlebars as standard and a full single colored fairing. The ER-6n comes in 4 color options, orange, yellow or black with a champagne frame, and silver with a red frame. In addition the option of ABS brakes were made available for both the ER-6n and ER-6f. There is also a derivative of the ER-6 called the Versys which utilises many of the component parts. In many European countries the ER-6n naked version has proven considerably more popular than the 6f.
