The Yamaha YZF-R1 is an open class sport bike,[1] or superbike,[2][3][4] motorcycle manufactured by Yamaha Motor Company since 1998.

1998–1999

Yamaha launched the YZF-R1 after redesigning the Genesis engine to offset the crankshaft, gearbox input and output shafts. This "compacting" of the engine yielded a huge dividend in that the total engine length was now much shorter. This allowed the wheelbase to be shortened significantly which resulted in much quicker handling and an optimized center of gravity. The bike had a compression ratio of 11.8:1 with a 6-speed multi-plate clutch transmission.

The launch model Yamaha YZF-R1 was available either in white-on-red or in blue. Early models were subject to a worldwide recall for a clutch problem. Yamaha today describes the launch of the R1 as the true value of "Kando".[5][clarification needed]

2005 YZF-R1 instrumentation

The 1999 R1 saw only minor changes apart from paint and graphics. Notable improvements were a redesigned gear change linkage and the gear change shaft length which was increased for better gear shifting. Fuel tank reserve capacity was reduced from 5.5 L (1.2 imp gal; 1.5 US gal) to 4.0 L (0.88 imp gal; 1.1 US gal), while the total fuel tank capacity was unchanged at 18 L (4.0 imp gal; 4.8 US gal). A second worldwide recall was issued for 1998 and early 1999 models to change a coolant hose clamp under the fuel tank which could come loose under hard use.

Motorcycle Consumer News tests of the 1998 model year YZF-R1 yielded a 0 to 60 mph (0 to 97 km/h) time of 2.96 seconds and 0 to 100 mph (0 to 161 km/h) of 5.93 seconds, a ¼ mile time of 10.19 seconds at 131.40 mph (211.47 km/h), and a top speed of 168 mph (270 km/h), with deceleration from 60 to 0 mph (97 to 0 km/h) of 113.9 ft (34.7 m).[1] For the 1999 model year, Cycle World tests found a 0 to 60 mph (0 to 97 km/h) time of 3.0 seconds, ¼ mile time of 10.31 seconds at 139.55 mph (224.58 km/h), and a top speed of 170 mph (270 km/h).[6]

2001 YZF-R1

2000–2001

In 2000, Yamaha introduced a series of changes to improve the bike, plus minor changes to the body work to allow for better long-duration ride handling. The R1 was an excellent bike to ride on short runs, but due to its quick handling was not a favorite long-ride bike. Yamaha's main design goal was to sharpen the preexisting bike and not redesign it. Even so they instituted over 150 changes in hopes of making an already light, sleek and mean motorcycle even lighter, sleeker and meaner. For example, even with the addition of the new Air Induction System, which weighs four pounds, the overall weight of the bike is down five pounds to 414 lb (188 kg)[7] dry. At 127.8 bhp (95.3 kW) at the rear wheel,[7] top-end output remains the same but changes to the engine management system are supposed to result in a smoother, broader distribution of power. The bodywork is 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. These redesigns changed the bodywork to a large enough degree that previous years' bodywork will not fit the 2000 model. The seating area was also updated. The fuel tank was reshaped with a more relaxed rear angle and deeper leg recesses to provide for better rider feel. The seat extended further towards the front 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, sharpening what was already a very sharp package. Engine-wise, the carburetors were rejetted 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 use internal oil ways to lubricate journals that, when combined with reduced tappet clearance, provided less friction and create 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 nixing the 1998 - 1999 generation's transmission complaints as well as helping to transfer as seamlessly as possible the R1's prodigious power to the tarmac.

2002–2003

2002 YZF-R1 with aftermarket high-mount exhaust

A new fuel injection system was introduced for the 2002 year, which worked like a carburetor by employing a CV carburetor slide controlled by vacuum created by the engine. With a similar power output to the 2000-2001 bike, the engine was remained largely the same. 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 2002, Yamaha released the newly developed "Deltabox III" frame,[8] which, with its hydro formed construction, dramatically reduced the total number of frame welds. These changes improved the frame's rigidity by 30%. 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 2002, between the higher definition headlights and also side "parking" lights within the twin-headlight panel, giving a more angular appearance. This also gave additional after market possibilities, such as to remove the front blinkers and utilize these front lights as directional or hazard markers while stopped. For 2003, the only change was the choice of colors, fitted hazard warning lights and dipped headlights, which stay on all the time the engine is running. The previous years all had a "Red" option, but this was replaced by a black with red flames "Special Edition" which cost an extra $100.

In 2002, Cycle World reported fuel mileage of 38 mpg[convert: ambiguous unit], a 0 to 60 mph (0 to 97 km/h) time of 2.9 seconds, a ¼ mile time of 10.32 seconds at 137.60 mph (221.45 km/h), and a top speed of 167 mph (269 km/h).[9]

2004–2005

2004 YZF-R1

With the competition advancing, Yamaha took to a major development. This included style updates like an under seat twin exhaust, and performance upgrades including radial brakes and for the first time on an R1 Ram-air intake. Furthermore, the wheelie-tendency known from earlier productions is drastically reduced by changing frame geometry and weight properties. The all new engine (no longer used as a stressed member of the chassis) featured a separate top crankcase and cylinder block. The 2004 R1 produces 132-134[10] hp at the rear wheel, and also weighs 172 kilograms (dry). The conventional front brake calipers were replaced by radially-mounted calipers, activated by a radial master cylinder. Also newly added for this year was a factory installed steering damper. Combined with the changes to the frame, it helped to eliminate the tendency of the handlebars to shake violently during rapid acceleration or more so during deceleration on downgrade and less-than-perfect surfaces (aka "tank slapping").

2006 YZF-R1

2006

The 06 R1 produces 132-134 horsepower at the rear wheel.[10] In addition, the swingarm was extended 20 mm longer due to acceleration instability. Also, in 2006 the 50th anniversary of Yamaha racing in America, Yamaha released the limited edition version in original Yamaha racing colors. The model (LE/SP) featured a Kenny Roberts replica paint pattern with yellow and black paint, and front and rear custom Öhlins suspension units developed by the people who work on the YZR-M1 MotoGP bike. Custom forged aluminum Marchesini wheels specifically designed for the LE shaved nearly a pound of unsprung weight. And a back torque-limiting slipper clutch, and an integrated lap timer rounded out the package making the LE more of a production racer. Only 500 units were made for the United States.

2007-2008 YZF-R1

2007–2008

2007 Yamaha YZF-R1 used by Noriyuki Haga in the Superbike World Championship.

An all-new YZF-R1 for the 2007 model year was announced on 8 October 2006. Key features include an all-new inline four-cylinder engine; going back to a more conventional four-valves per cylinder rather than Yamaha's trade mark five-valve Genesis layout. Other new features are the Yamaha Chip Control Intake (YCC-I) electronic variable-length intake funnel system, Yamaha Chip Control Throttle (YCC-T) fly-by-wire throttle system, slipper-type clutch, all-new aluminum Deltabox frame and swingarm, six-piston radial-mount front brake calipers with 310 mm discs, a wider radiator, and M1 styling on the new large ram-air ports in the front fairing. 2008 brought BNG[clarification needed] and the ability to buy limited edition Fiat plastics. Power was 152.9 hp (114.0 kW) @ 10,160 rpm.[2]

2009–2010

In late 2008 Yamaha announced they would release an all new R1 for 2009. The new R1 takes engine technology from the M1 Motogp bike with its cross plane crankshaft, the first ever production motorcycle to do so. Crossplane technology, puts each connecting rod 90° from the next, with an uneven firing interval of 270°- 180°- 90°- 180°. The idea of this technology is to reduce internal crankshaft torque, thus giving the new R1 a more linear power delivery. Yamaha claims the bike would give the rider 'two engines in one', the low end torque of a twin and the pace of an inline four. As with previous incarnations of the R1 the 2009 model keeps its YCC-T (Yamaha Chip Controlled Throttle). The R1 now produces 136-138 hp at the rear tire. Which is more than enough power for an average ride such as Timothy Liska.[10]

Another advancement included on the 2009 model is D-Mode Throttle Control Valve Mapping which allows a rider to choose between three distinct maps depending on the rider’s environment. Each mode of operation controls YCC-T characteristics changing how the R1 reacts to driver input. The first mode is Standard Mode, which delivers performance for a wide variety of driving conditions. The second mode is "A" mode which will give a rider more available power in the lower to middle RPM range. The third mode is "B" mode, which is a dial back of the previous mode, designed to soften throttle response in inclement weather and heavy traffic. D-Mode throttle control is controlled via the rider through a forward mode button near the throttle. The instrument panel is more comprehensive than previous models and the 2009/2010 Yamaha YZF-R1 model now features a gear indicator as standard.

Overall handling of the R1 was improved through several changes to frame and suspension. A new sub frame was designed for the 2009 R1 which is magnesium cast in a carbon fiber mold. This new subframe offers a superior strength to weight ratio, while helping keep mass closer to the center of gravity and subsequently gives the bike greater handling performance. The rear shock absorber on the 2009 offers variable speed damping as well as an easy to tweak preload via a screw adjustment. The rear shock now connects underneath the swing arm through different linkage; a change from previous years models. Front suspension takes its cues from the M1 as the left fork handles compression damping while the right controls the rebound duties. To improve overall handling and safety, this is the first year Yamaha developers included an electronic steering damper on a production R1.

The overall look of the R1 has changed drastically. In a side by side comparison between last year’s model and the 2009; to the eye, the 2009 looks much more compact and could be compared to the size of the R6r. The center up exhaust on the 2009 seems significantly larger compared to previous years, due in some respects to changes in emissions controls. The front has the same classic R1 shape, though the air intake location and headlamp design have been revamped on the 2009 model; utilizing only projector lamps and using the new found design space within the nose cone to reroute ram air tubes next to the lights.

Testing the 2010 model year, Motorcyclist reported a ¼ mile time of 10.02 seconds @ 144.23 mph (232.12 km/h), a top speed of 165 mph (266 km/h), and fuel mileage of 25 mpg[convert: ambiguous unit].[11]
