Kawasaki Z750
From Wikipedia, the free encyclopedia
The Z750 motorcycle is Kawasaki's model in the budget class of naked and half faired bikes. It is a smaller version of the Kawasaki Z1000.
The Kawasaki Z750 was launched in 2004, after its bigger brother, the Z1000 in 2003. Kawasaki kept it simple, using the same engine block and sleeving it down from 1000cc to 750cc, cheaper front suspension and using a conventional exhaust, making it a cut-down version of Z1000. Like the Z1000, which is considered a modern version of the Kawasaki Z900/Z1, the Z750 can be considered a modern take on the Kawasaki Z750RS Z2. A remodeled version of both the Z750 and the Z1000 was released in 2007, with changes both stylistically and mechanically.

[edit] Variants
In 2005, Kawasaki launched the Z750S version which is more tourer, and less streetfighter. This version has a single long seat instead of the two-part seat on the Z750 similar to the Kawasaki ZXR600R, half fairing for wind protection, and excludes the rear tire "hugger" as found on the unfaired Z750. The 'S' version also uses an analog speedometer and tachometer instead of the digital instrument cluster taken from Kawasaki's supersport ZX-R models of which some riders complain that the digital LCD tachometer was harder to read while riding. Other differences inclue a slightly lower seat, grab rails and ZX10 style rear brake lights.
[edit] Common Complaints
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 2005-2006 model Z750S produces a lot of vibration from the running engine. This causes a problem commonly referred to as "fairing buzz". On this model motorcycle, the buzz tends to be most noticeable around 6000-8000RPM, above an indicated 75mph.
The aforementioned 2005-2006 vibrations are also very noticeable in the stock mirrors, so much that many riders claim that the mirrors are useless once you enter the base vibration range of 5000RPM until high RPM. There have been numerous attempts to get around this vibration while maintaining the stock mirrors. As of yet, Kawasaki has not announced any plans to fix this in the current model Z750S. A proposed fix from some is to replace them with mirrors from the Buell XBR12 Firebolt.
