Kawasaki zx-7R


The ZX-7R has a 749 cc in-line four-cylinder, four-stroke engine.

The frame used on the ZX-7R is a lightweight aluminum twin-spar item, designed using computer-aided design to optimize strength. The rear subframe was constructed using steel, providing enough strength for a pillion passenger.

The swingarm used largely the same fabrication techniques to produce a hollow cast and pressed aluminum alloy hybrid swingarm, and the Uni-Trak rear suspension system features a predominantly lightweight alloy and aluminum construction. The Uni-Trak system was designed to provide a progressively stiffer damping and spring rate under compression. The rear suspension unit is fully adjustable in terms of damping, preload and compression.

The front suspension found on the ZX-7R comprises a fully adjustable 8-way compression and 12-way rebound 43 mm inverted cartridge fork.

Front brakes are 320 mm semi-floating front discs and Tokico six-piston calipers. Rear brakes feature a 230 mm disc with a twin-piston opposed caliper.

The ZX-7RR differs from the road model with an adjustable head-stock angle, swing arm pivot, additional increased adjustability 28-way compression and 13-way rebound to the front and 14-way rebound for the rear suspension, ten more than the R model, a solo cowl with a different aluminum subframe, and 41 mm flat-slide carburetors versus the 38mm on the base R model. It also has a close ratio gear-box fitted as standard and a crankshaft flywheel that is heavier and Nissin front brake calipers.[2][6][7]

Cycle World recorded a 0 to 1⁄4 mi (0.00 to 0.40 km) time of 10.82 seconds at 129.68 mph (208.70 km/h).

The 2012 model drops the   R   suffix from its name. [2]   It is a middleweight,   parallel-twin   engined motorcycle, designed for normal use on paved roads. They have modern styling and features, with low-seating ergonomics and a low   center of gravity . The engine has a 180° crankshaft, resulting in an   uneven firing interval   of 0° and 540°. The 650R and its  naked  sibling, the ER-6n, were introduced in 2006. The naked ER-6n was not sold in North America until the 2009 model year. The motorcycle fits above the  Ninja 250R  and  Ninja 500R  models, which already existed in Kawasaki's sportbike lineup, which includes the Ninja ZX models. For 2009, Kawasaki released an updated Ninja 650R which in...
