The bike has a 6-speed transmission. Power was moderated via the wet multidisk, manual.
It came with a 120/70-zr17 front tire and a 180/55-zr17 rear tire. Stopping was achieved via double disc. optional abs. dual twin-piston. in the front and a single disc. optional abs in the rear. The front suspension was a 41 mm inverted fork with rebound damping while the rear was equipped with a bottom-link uni-trak with gas-charged shock stepless 7-way.

ZR750 K1/K6F Z750S
Z750 was presented in 2004, after Z1000 great success in 2003. Kawasaki played simple, they used same engine block, cheaper front suspension and much simplier exhaust making a cut-down version of Z1000. Apperance was a bit less aggresive and "eye catching" the fun factor stayed equally high and the price was significatly lower.
Z750 easily manages to defeat his competitors (Yamaha FZ6 and Fazer, Suzuki GSR600, Bandit 650, SV650(s), Honda CB600(France)) in most head-to-head comparisons thanks to great engine. Thanks to 100-150 ccm of extra displacement Kawasaki was able to make Z750's engine much more torque and responsive in low and mid engine speeds compared to other budget middleweights, especially Yamaha's which are equally fast but demand much more revs. Naked and half faired sport bikes are much more about commuting in city and cruising on short journeys than speeding and revving the engine "in red" so Kawasaki made a real good job with Z750's engine. Bigger engine costs more so Kawasaki had to go with the steel frame, while all other manufacturers use aluminum which made Z750 heaviest in class. This is only real con for Z750, but few extra kilos was easily "canceled" with more power and torque. By many, this is cheating because for years this class was populated with 600-650ccm bikes, but consumers really don't care, they get faster and more exciting bike for same money. Aggresive "streetfighters" styling makes Z750 very attractive and eye catching, which is another category which makes naked bike great.
In 2005, Kawasaki presented Z750S version which is more tourer, and less streetfighter. This version has one big seat instead of two part seat on Z750, bigger fairing for wind protection, doesn't have rear tire "hugger" like Z750 and uses analog speedometer and tachograph instead great looking digital instruments taken from ZX-R models on Z750 and Z1000

A standard Z750 will make almost 100 hp at the rear wheels, and swapping the muffler for an easier-breathing item will yield slightly over that figure. The power is delivered in a seamless stream with no large dips or troughs but it still manages to deliver a furious top end rush. The fuel injection is a sophisticated dual-butterfly system usually found on more expensive bikes. One butterfly is controlled by the rider while the other is controlled by the EFI. It delivers smooth and usable power from just over tick-over to the 11,500 rpm redline.
The brakes are quite basic, two pot floating units. They lack feel with the standard brake lines but still give a surprising amount of power.
Handling wise the Z750 is much more than the sum of its parts. The wide bars allow the rider to flick between corners with ease and the bike handles lumps and bumps in the road better than any sports bike. The pegs will touch down quite easily but this is more due to the bike's ability than their low placement.
The small screen doesn't offer much protection at high speeds, especially at its 245 km/h indicated top speed! The riding position is very comfortable with a classic naked bike style - sit up and beg. The pillion position is less accommodating with a small peg-to-seat height and no real grab-handle. The 18 liter tank allows for a much larger than average cruising range.
2004 - 2006 Kawasaki Z 750
The Z 750, a motorcycle manufactured by Kawasaki between 2004 and 2006, was available in only three colors, namely blue, black and red.
2005 - 2012 Kawasaki Z750
2012 was the last year of production for the Kawasaki Z750. This naked bike remains an iconic presence in the naked motorcycle segment, standing as a milestone for mixing together maneuverability, fast cornering, a powerful and swift engine, aggressive styling and comfort.
The result was a motorcycle high-capable for daily commuting and sporty touring alike, with fully-adjustable fork and rear shock, optional ABS and countless accessories for both visual and functional upgrades.
Its 226 kg weight and 106 PS engine have remained intact in this last production year, and the Z750 ended its cycle as a highly-revered street bike being favored by numerous riders looking for machines combining the higher power closing to that of a 1 liter engine and the lightweight design of a middle-class one.
2006 Kawasaki Z750
The 2005 Kawasaki Z750 carries on the characteristics of the first model in the series. This naked bike is powered by a liquid-cooled 748cc 4-cylinder engine with electronic fuel injection for a smooth power delivery across a wider rpm range.
The Z 750 can be used for riding to work on a daily basis but it can also surprise you on the race track: it's derived form the acclaimed Z1000 beast and both character and looks proudly show it.
With a 110 PS max power and 195 kg dry weight, the 2005 Z 750 comes with a generous 18 L tank which makes it simply great for longer trips and sport-touring. The rear suspension comes with a 4-way rebound adjustable rear suspension and 7 spring preload settings, for the max comfort on any roads.
Multiple accessories are available for both optical tuning and overall performance and functionality.
2006 Kawasaki Z 750 S
Equipped with dual 300mm discs with 2-piston calipers front brakes and with single 220mm disc with 1-piston calipers rear brakes, the Z750S naked by was first manufactured by Kawasaki in 2006.
2007 Kawasaki Z 750
The Kawasaki Z750, the 2007 model which is available in three colors, black, silver and green, was able to reach a top speed of 230 km/h.
2008 Kawasaki Z750
For the 2008 MY, the Kawasaki Z750 has received some technical advances, and the most important is the addition of adjustable forks, a premiere in the model's history.
The now fully-adjustable bike can be easily tuned for the best performance on multiple surface types and riding styles, no matter whether you're driving on a race track, cross-town, or on fast-bend mountain roads.
The liquid-cooled in-line 4-cylinder power unit now delivers 106 PS and the dry weight has increased a bit, to 203 kg. Dimensions and seat height have remained the same, so maneuverability is still top-notch.
Metallic Ocean Blue, Ebony and Pearl Wildfire Orange are the available colors for 2008.
2012 Kawasaki Z750R
The 2012 MY Kawasaki Z750R brings a stunning new look and some frankensteined parts from its older, more powerful brothers, such as the 41 mm inverted front fork that has been borrowed from the 2009 MY Z1000. Add to this the bottom-link Uni-Trak rear suspension with a nitrogen gas-charged shock and a piggyback reservoir, and the end result is one of the most smooth rides a motorcycle can give you.
The liquid-cooled engine with efficient 4-valve, DOHC cylinder head displaces 748 cm3 and can produce 106 horse power, making this new model from Kawasaki not only comfortable, but also a force to be reckoned with when it comes to speed and acceleration.
The improvement that distinguishes the Z750R from the Z750 is the multi-piece front cowl , with it's bold and aggressive multi-facet design, making it not only a smooth and fast motorcycle, but also a sight for sore eyes.
