YAMAHA R1 2001

In 2000, Yamaha introduced a series of changes to improve the bike, and minor changes to the bodywork to allow for better long duration ride handling. Yamaha's main design goal was to sharpen the pre-existing bike and not to redesign it. The dry weight was reduced five pounds to 414 lb (188 kg).[5]

At 127.8 hp (95.3 kW) at the rear wheel, top-end output remained the same, but changes to the engine management system were intended to result in a smoother, broader distribution of power. The bodywork was still unmistakably R1, although a few changes were made resulting in a 3% reduction in the drag coefficient. The headlight housing's profile was sharpened, the side panels were made more aerodynamic and slippery, and the windscreen was reshaped for better rider protection.

The seating area was also updated. The fuel tank was reshaped, with a more relaxed rear angle and deeper leg recesses to provide for a better rider feel. The seat extended further towards the rear of the tank and the new, steeper, seating position put additional weight on the front end. All of this was aimed at improving weight bias and offering sharper cornering and more stability.

Mechanically, the carburetors were re-jetted in an effort to improve throttle response, especially in the low end, all the way up to the bike's 11,750 rpm redline. The redesigned camshafts were lightened and used internal oil ways to lubricate journals that, when combined with reduced tappet clearance, provided less friction and created less engine noise. The gearbox received a taller first gear, a hollow chrome moly shift shaft with an additional bearing and a completely redesigned shift linkage and foot pedal. These changes were aimed at eliminating problems with the transmission in earlier models, and to help to seamlessly transfer the bike's power to the road.

 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 ar...

ER_6F @ NINJA 650R The  Kawasaki Ninja 650R , also called   ER-6f   or   EХ-6 , is a motorcycle in the   Ninja   series from the Japanese manufacturer   Kawasaki   sold since 2006. 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...
