new YZF-R1

A Person puts his passion,skill,hardwork and determination together to make a masterpiece. when it comes to Yamaha they have put their years of hard work, technology and their hart together and made a masterpiece and named it as YAMAHA YZF-R1.

History:

1998 R1

In 1998 Yamaha launched the YZF-R1 after redesigning the Genesis engine to offset the crankshaft, gearbox input, and output shafts. This "compacting" of the engine made the total engine length much shorter. This allowed the wheelbase to be shortened significantly, resulting in much quicker handling and an optimised center of gravity. The bike had a compression ratio of 11.8:1 with a six-speed transmission and multi-plate clutch.
In 1999 Notable improvements were a redesigned gear change linkage and the gear change shaft length being increased. Fuel tank reserve capacity was reduced from 5.5 to 4.0 litres


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.they're gole was to reduce the weight of the light bike even further .
For example, even with the addition of the new air induction system, which weighed four pounds, the overall weight of the bike was down five pounds to 414 pounds (188 kg) dry.

A new fuel injection system was introduced for the 2002 year. One notable improvement was the use of new cylinder sleeves of a high silicon content alloy containing magnesium that minimised heat induced distortion, reducing oil consumption. Also in 2002, Yamaha released the newly developed "Deltabox III" frame, 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.

For 2003, the only change was fitted hazard warning lights and dipped headlights, which stay on all the time the engine is running.

2004 R1

2004 was the year when r1 took it beautiful shape which is still continued today


This engine features forged aluminum pistons to take maximum advantage of the power characteristics. Titanium intake valves are lightweight.

A forced-air intake system is adopted to increase intake efficiency by using the natural airflow during riding to pressurize the air in the air box. This contributes to outstanding power delivery characteristics in the high-speed range, while the design also helps to minimize intake noise.

Slipper-type back torque-limiting clutch greatly facilitates braking/downshifting from high speed.

The exhaust system is meticulously designed to enhance engine output while, thanks to its three-way catalyst technology, also reducing exhaust emissions. The silencer is a single expansion type, and the sound coming through from the unique crossplane-crankshaft-equipped engine is unlike any other inline-four cylinder production supersport.

This fuel-injected engine takes full advantage of YCC-T (Yamaha Chip Controlled Throttle), the MotoGP®-inspired fly-by-wire technology used to deliver instant throttle response. There’s also YCC-I, Yamaha Chip Controlled Intake, the variable intake system that broadens the spread of power.

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 featured a separate top crankcase and cylinder block

For 2006, the swing arm was extended by 20 millimetres to reduce acceleration instability. In this year, Yamaha also released a limited edition version in original Yamaha racing colors to celebrate its 50th anniversary. The model (LE/SP) featured a Kenny Roberts front and rear custom Öhlins suspension units developed by the same team as the YZR-M1 MotoGP bike. Custom forged aluminum Marchesini wheels specifically designed for the LE shaved nearly a pound off the unsprung weight. A back torque-limiting slipper clutch, and an integrated lap timer rounded out the package, making the LE virtually a production racer. Only 500 units were made for the United States with another 500 units for Europe.

Yamaha r1 special edition

An all-new YZF-R1 for the 2007 model year was announced on 8 October 2006. Key features included 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 were 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. There were no major changes for 2008

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 variations of internal crankshaft speed, 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).

R1 with custom exhaust

Another advancement included on the 2009 model was 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 mid 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 by 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.

The overall look of the R1 has changed drastically. In a side by side comparison between the 2007 and 2009 models, the 2009 looks much more compact and could be compared to the size of the R6. The center-up exhaust on the 2009 is significantly larger compared to previous models, due 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.

Yamaha r1

As we saw Yamaha has installed all class leading technology's into the r1 now in 2012 Yamaha has introduced it with 6 Laval traction control system.

Now they are going to release a new model for 2013 following are key features offered by new R1

all new r1

• The YZF-R1 benefits from MotoGP® technology – a seven-level Traction Control System. The system has been developed so the rider does not feel any unnatural or harsh intervention from the system. In addition, traction control can aid in reducing tire wear due to less wheel spin. Coupled with the three level D-Mode electronic throttle response control, riders have 21 different choices available to tailor the YZF-R1 to their riding preference.

• This R1 keeps all the technological superiorities developed for its predecessor: YCC-T™ (Yamaha Chip Controlled Throttle) is MotoGP® inspired fly-by-wire technology used to deliver instant throttle response. YCC-I® is Yamaha Chip Controlled Intake which is a variable intake system that broadens the spread of power. The fuel injection system provides optimum air/fuel mixtures for maximum power and smooth throttle response.

• In keeping with this machine’s exceptional cornering ability and crisp handling, the aluminum frame has been designed to offer exceptional rigidity balance. The rear frame is lightweight Controlled-Fill die-cast magnesium, contributing the optimum mass centralisation. Suspension includes YHSJ (Yamaha Hydraulic Systems Japan) front forks which use one of the tricks developed for our winning MotoGP® bikes: independent damping. The left fork handles compression damping and the right side handles the rebound damping. And the rear shock adopts bottom linkage for optimum suspension characteristics.

• The sound on the YZF-R1 is unlike any other inline-four cylinder production supersport. The precise and throaty pulse of the exhaust note will have riders enthused every time the throttle is opened.

Engine:

R1 2013

• Crossplane crankshaft technology proven in victory after victory on MotoGP® machines provides a high-tech uneven firing interval. Unlike typical inline-four engine design, where the two outer and two inner pistons move together in pairs with 180°intervals, the crossplane crankshaft has each connecting rod 90° with a unique firing order of 270° –180° – 90° – 180°. This overcomes the inherent fluctuations in inertial torque during each engine revolution, and the accompanying peaky torque characteristics. Instead, combustion torque continues to build, giving the rider more linear throttle response with awesome power and traction out of the corners.

• Seven-level Traction Control System allows the rider to get more traction and drive while exiting corners.

• To maximize rider comfort as well as power output, the engine adopts a coupling-type balancer that rotates in the opposite direction as the crankshaft.

• This engine features forged aluminum pistons to take maximum advantage of the power characteristics. Titanium intake valves are lightweight.

• A forced-air intake system is adopted to increase intake efficiency by using the natural airflow during riding to pressurize the air in the air box. This contributes to outstanding power delivery characteristics in the high-speed range, while the design also helps to minimize intake noise.

• Slipper-type back torque-limiting clutch greatly facilitates braking/downshifting from high speed.

• The exhaust system is meticulously designed to enhance engine output while, thanks to its three-way catalyst technology, also reducing exhaust emissions. The silencer is a single expansion type, and the sound coming through from the unique crossplane-crankshaft-equipped engine is unlike any other inline-four cylinder production supersport.

• This fuel-injected engine takes full advantage of YCC-T (Yamaha Chip Controlled Throttle), the MotoGP®-inspired fly-by-wire technology used to deliver instant throttle response. There’s also YCC-I, Yamaha Chip Controlled Intake, the variable intake system that broadens the spread of power.

Chassis/Suspension:

• The frame has a combination of uncompromising rigidity where needed along with carefully achieved flex for the precise rigidity balance this bike needs to give the rider the full benefit of its handling and engine characteristics. It is a sophisticated combination of Controlled-Fill die-cast, stamping, and gravity casting… the exact technology needed for each portion of this advanced frame.

• Front forks take a page from the championship-winning design of our MotoGP® weapon, the M1. Since both forks always move together, compression damping duties can be confined to the left fork, while rebound damping is precisely handled by the right fork, reducing oil cavitation.

• The rear shock features both high and low speed compression damping plus an easy-to-use screw hydraulic adjustment for preloaded. This unit also adopts a pillow-ball-type joint for exceptional shock absorption, road hold feeling, and damper response. To achieve maximum performance, a bottom linkage is used to work with the rest of the chassis refinements for brilliant, crisp handling characteristics.

• Factory racers get machines tailored to their preferences. Welcome to the club. R1 has adjustable footrests, with a 15mm height and 3mm front-to-rear adjustment.

• Top triple clamps add to the appearance of the YZF-R1, reminiscent of those on the MotoGP® powerhouse YZR-M1.

• LED position lights enhance the YZF-R1’s unique styling.

Additional Features:

• The instrumentation includes everything a rider wants to know, including gear position.
• Have it your way, thanks to Yamaha D-MODE (or “Drive Mode”) variable throttle control. There are three modes that control how YCC-T responds to throttle input from the rider. The selectable “A” mode puts more emphasis on engine response in low to mid range rpm. “B” mode, on the other hand, provides less sharp response to input for riding situations that require especially sensitive throttle operation. The standard map is designed for optimum overall performance. Selecting the map you want is as easy as pressing a button on the handlebars.

Conclusion:

R1 is a true masterpiece which took many tweaks and developments which made it more desirable bike. this beast sounds unlike any other bike on the rode looks beautiful with its unique style and got best engine in it which made it more unique from others . but from many reviews i noticed that r1 is somewhat harder to control than other bikes in the class .because its engine is really very powerful you get a lot of power delivery even in low RPM which is good on track but while you are commuting it feels somewhat difficult to handle it on normal roads so in starting it may feel difficult but once you get control on this beast there's no one out there can stop you . Yamaha also gave us 3 power delivery settings so now you can even control it in  different roads in just one click but believe me once you get control on the bike you will never use those settings.now the new traction control system offers more confidence to the rider to push the bike to its limits that means more joy.every Pennie of it is worthy Yamaha never disappoints its costumers. and i wish Yamaha will develop the r1 much further and make it even beater YES YAMAHA.
