Yamaha YZF R1 Wikipedia.The Yamaha YZF R1, or R1, is an open class sport bike,1 or superbike,234motorcycle manufactured by Yamaha Motor Company since 1.Yamaha launched the YZF R1 after redesigning the Genesis engine to create a more compact engine by raising the gearbox input shaft and allowing the gearbox output shaft to be placed beneath it.This design feature was revolutionary, called a stacked gearbox, it has set a precedent for other manufacturers to follow.This compacting of the engine made the total engine length much shorter overall, thereby, allowing the wheelbase of the motorcycle to be shortened significantly.This, in turn, allowed the frame design to place the weight of the engine in the frame to aid handling because of an optimized center of gravity.The swingarm was able to be made longer without compromising the overall wheelbase, which was a short 1.Four Kehin CV carburetors of 4.USD 4.KYB mounted 3.The instrument panel was electrical with, self diagnosis system inbuilt, and digital speed readout.The exhaust system utilised an EXUP valve, which controlled the exhaust gas flow, to maximise engine power production at all revs, creating a high powered but also torquey engine.Yamaha-YZ125T1-2005-manual.jpg' alt='2005 Yz250 Service Manual Free Download' title='2005 Yz250 Service Manual Free Download' /> CLICK HERE FOR MORE IMAGES.XT Racing GPX ZED GPS Lap Timer Data Recorder.Ref 61514.SPECIAL OFFER NORMALLY 359 SAVE 60 SelfPowered, USB.List Of Book Kawasaki Z750 2007 2010 Service Repair Manual,Hp P4500 G2 Manuals,Manual Do Google Earth Pdf,Cbse Guide Of10th Class For Economics,Yamaha Raptor 90.The Yamaha YZFR1, or R1, is an open class sport bike, or superbike, motorcycle manufactured by Yamaha Motor Company since 1998.The twin headlights were powerful.The Yamaha YZF R6 was introduced in 1.R1 super bike.

The 1.R1 saw only minor changes, apart from paint and graphics.More improvements were a redesigned gear change linkage and the gear change shaft length being increased.Fuel tank reserve capacity was reduced from 5.US gal, while the total fuel tank capacity was unchanged at 1.US gal.Motorcycle Consumer News tests of the 1.YZF R1 yielded a 0 to 6.For the 1.Cycle World tests found a 0 to 6.In 2.Yamaha introduced a series of changes to improve the bike, and minor changes to the bodywork to allow for better long duration ride handling.Yamahas main design goal was to sharpen the pre existing bike and not to redesign it.The dry weight was reduced five pounds to 4.At 1.W at the rear wheel,6 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 housings 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 bikes 1.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 molyshift 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 bikes power to the road.YZF R1 with aftermarket high mount exhaust.A new fuel injection system was introduced for the 2.CV carburetor slide controlled by vacuum created by the engine.With a similar power output to the 2.One notable improvement was the use of new cylinder sleeves of a high silicon content alloy containing magnesium that minimized heat induced distortion, reducing oil consumption.Also in 2.Yamaha released the newly developed Deltabox III frame,7 which, with its hydro formed construction, reduced the total number of frame welds.These changes improved the frames rigidity by 3.The cooling system was redesigned for better performance and compactness.The exhaust system was changed from a 4 into 1 to a new titanium 4 into 2 into 1 design.The rear end of the motorcycle was updated and streamlined with a LED taillight.This allowed for very clean rear body lines when choosing one of several common after market modifications, such as removal of the turn signal stalks and stock license plate bracket and replacing them with assorted available replacements that hug the body or frame.Also, front end lighting was improved in 2.This also gave additional after market possibilities, such as to remove the front turn signals and use these front lights as directional or hazard markers while stopped.For 2.In 2. 00. 2, Cycle World reported fuel mileage of 3.US 6.L1. 00 km 4.With the competition advancing, Yamaha made some major changes to the model.This included style updates, like an under seat twin exhaust, and performance upgrades including radial brakes, and, for the first time an R1 Ram air intake.Furthermore, the tendency for wheelies by earlier productions was reduced by changing the geometry of the frame and weight distribution.The all new engine was no longer used as a stressed member of the chassis, and had a separate top crankcase and cylinder block.YZF R1 instrumentation.The 2.R1 weighs 1.The conventional front brake calipers were replaced by radially mounted calipers, activated by a radial master cylinder.A factory installed steering damper was also added this year.Combined with the changes to the frame, this helped to eliminate the tendency of the handlebars to shake violently during rapid acceleration or deceleration on less than perfect surfaces, a phenomenon known as a speed wobble or tank slapper.Motorcycle Consumer News tests of the 2.YZF R1.S yielded a 0 to 6.John Mc.Guinness won the senior race at the 2.Isle of Man TT.For 2.In this year, Yamaha also released a limited edition version in original Yamaha racing colors to celebrate its 5.The model LESP had a Kenny Roberts front
