Before 2014 show in Milan, YAMAHA released a new generation of R1, not only drastically change the appearance, full shadow YZR-M1 MotoGP factory bike outside, which scored nine-time world championship and Valentino Rossi involved in the development. YZF-R1 equipped with a large number of electronic control equipment, and has 200ps horsepower and 199kg wet weight of amazing horsepower to weight ratio, while in addition to the standard version of the R1, but it also delivered a track performance version called the YZF-R1M.
The new engine technology from M1 decentralization, the same straight four 998cc Cross crankshaft 270 ° – 180 ° – 90 ° – 180 ° firing interval ranging from design. Cross crank the engine can be said that with the heart, through the cross crankshaft configuration to achieve the throttle opening and the rear output close to 1: 1 ratio. This represents the power R1 can be more direct feel knight grasped, so that up to 200ps of horsepower can be fully realized. On the M1 intake design is also imported to the new R1, the new intake system to adjust the amount of air intake characteristics, so that the overall optimization, thereby reducing loss of horsepower, making the new engine under Excluding Ram-Air could have 200ps of horsepower output. The new cross crankshaft R1’s new engine is not just bore, stroke, compression ratio change, even the most important cross-crank is also different from the previous generation. 2015 R1 crankshaft inertia is set lower than the previous generation 20%, through the close of the outer cylinder lightweight balancer shafts, to react quickly while maintaining linear engine torque output.
The new cross crankshaft using titanium rod.
Pioneered the use of commercially available titanium rod.
2015 R1 using high strength lightweight titanium connecting rod fracture type, lightweight than 40% of the original steel rod, so that the engine can play to a higher speed, but also faster reaction. Breakages style design also provides greater precision connecting rod big end, and to avoid deformation of the connecting rod big end at high rotational speeds, in ensuring performance and reliability. High-performance cylinder head in order to improve combustion efficiency, 2015 R1 with a set of compression ratio up to 13: 1 in the cylinder head, inlet and exhaust doors also have increased, respectively, 33mm and 26.5mm. In addition, 2015 R1 engine intake and exhaust valve angle is smaller, so that the new engine has a more compact combustion chamber. This design allows the oil and gas can be more smoothly into the combustion chamber, and improve the overall speed and efficiency of combustion, and then let the engine with high output and good torque.
High efficiency cylinder head design, a smaller door into the exhaust angle, to achieve better combustion chamber design.
Lightweight forged aluminium pistons
2015 R1 using forged aluminium pistons, and through the bridge-box bottom piston structure, both at a high intensity light weight, and use of new oil spray piston cooling system. Under high intensity and light weight of 2015 R1 in power output and engine response with significant help. In addition, with low tension piston rings and class diamond carbon coating (DLC) treatment, but also to reduce the loss of power generated by friction. New Valve rocker institution in the history of R1 among the first to use the new agency with a lever arm than the design of steam valve, allowing the cam and valve lift is greater than the height of the load while reducing cam and friction loss. Also the use of high hardness DLC coating, which is a one of the key to 2015 R1 has such a strong output and engine response. Larger intake system under the new cylinder head design and valve, greater space above the engine, which makes 2015 R1 can carry 10.5 liters of gas gathering boxes, an increase of 23% compared with the existing R1. YAMAHA more air under variable inlet YCC-I of the match, through computing, with time speed, better power output and torque characteristics.
More advanced electronic injection system
2015 R1 main nozzle mining bidirectional design, each nozzle has 12 holes, by YAMAHA own electronic throttle control systems YCC-T control, can provide the best fuel atomization. Two-way design allows maximum to avoid the main nozzle gasoline direct injection into the intake pipe wall, thus improving combustion efficiency in exchange for greater output. Make up enough of hydrocarbon at high speeds by another set of nozzles, and to reduce the temperature. 4-in-1 titanium exhaust pipe correspond to the new engine, 2015 R1 also adopted new full titanium exhaust pipe segment from the cylinder head to the bottom of the engine, the exhaust from head section 4 together for two and then combined into one, 5.2 liters of catalyst into the inside. When the exhaust pressure is low in the low speed, the valve will be closed from the tube, only two exhaust channels first. When high speed, discharge pressure increases, the valve will be fully open, so have a greater exhaust space. Exhaust pipe through the valve opening speed, power and performance to provide comprehensive exhaust noise.
The new design of the sliding clutch
The new A & S slipper clutch design with 2015 R1’s power, and the ratio of sliding off the current model by 19% lighter, the diameter is reduced by 7%. A & S slipper clutch cam aluminum alloy link between the clutch hub and clutch plate, for better power transmission. A & S slip away while providing the equivalent of a half-clutch-like smooth degree, so Knight reverse at high speed into the corner will be more smooth and shorten the lap time.
The new design of the sliding clutch, smaller and lighter.
Lightweight Delta Box frame
2015 R1 also use YAMAHA Delta Box frame, the multi-piece welded aluminium components, the new engine with a four-point fastening means within the frame. And after the aluminum casting and forging aluminium alloy swing arm made of two welded together, to reach a high strength aluminium alloy truss specification rocker. The use of magnesium alloy subframe is made lighter than aluminium, and, mutatis mutandis, the main frame using the left-right asymmetry design, light weight and achieve a more compact size.
Short wheelbase, ultra-lightweight
2015 R1 under asymmetric frame and lightweight components such as magnesium alloy oil pan, the whole car hit a 199kg wet weight, dry weight was more just 179kg. Lightweight pipe is only R1 a major focus of this generation, but for the performance curve, the wheelbase is YAMAHA engineers focused point. 2015 R1 wheelbase of 1,405mm, more shorter than the previous generation R1 a 10mm, rear swing arm length is 570mm, 15mm shorter than the previous generation, anteversion remains unchanged, but the front wheel axis increase 3mm to 25mm.
M1 type of pressurized air intake designed
to import a large number of air intake via hidden LED headlights in the middle of large diameter, through 10.5 liters of tap into the plenum chamber, made of plastic and fiberglass lightweight efficient Ram Air duct road, and it is the current M1 MotoGP factory car is the same design. For track suspension system developed by YAMAHA jointly developed with KYB adjustable front and rear suspension system-wide, 43mm inverted fork for using fork, actuator stroke of 120mm, 25mm front wheel axis and use, under heavy braking energy better road feel and damping sense. After the rocker has been calculated, with Motocross multi-link, after the turn of the ground can strengthen the power output of the reaction is determined using the power of the engine. After an additional tooth, the relative position of the arm length of the rocker shaft is also specially designed, to provide a stable acceleration process, and can accurately handle braking and steering actions.
After the suspension, high and low speed compression damping is adjustable design.
ABS and Unified Brake System (Combined Brake System)
This is the first time equipped with ABS and YAMAHA YAMAHA own braking system (UBS) in the Super Sport models, will take the initiative to join the appropriate time after the brake before using the brakes, however, when using When to use both the front and rear brakes, UBS will automatically balance the braking force between the two. The premise is involved through 6-axis inertial measurement device (IMU) mounted inside the vehicle, when the vehicle has the inclination, the rear brake actuator will not automatically ensure that the user can use according to their habits after stopping for a curve correction.
Cast magnesium alloy rims 2015 R1 for the pursuit of lightweight, becoming the first Japanese production sports car powered by a magnesium alloy rim cars. Star design uses ten claw magnesium alloy frame, aluminum alloy frame than the standard 900 grams lighter. Front wheels are lighter than the previous generation R1 530 grams, 4% handling stability, rear light 340 grams, 11% successful in reducing rear wheel inertia, for better handling. The tank car design car design from the M1 tank, and strengthen the body’s legs fixed surface, so that the rider can more easily close to the body, strengthen the integration of people and vehicles, and more conducive to heavy braking and cut corners.

M1 exterior front and a full set of LED lights
Similar to the M1 YAMAHA front appearance is the result of wind tunnel experiments under 8% to reduce wind resistance. Meanwhile, in order to reduce vehicle weight, LED headlamps and positioning lamps, the full realization of lightweight. HiD headlight fairing on both sides of the headlight lower than imitation game, and cleverly hidden within the fairing, the lighting was not the time, it is almost never found headlamps retain their factory racing success like appearance.
All riders in the pursuit the fastest lap wants full control of the vehicle. The 2015 YZF-R1 is equipped as standard production is the most advanced electronic control system electronic equipment, as the latest generation of the superbike debut. 6-axis inertial measurement device (6 axis Inertial Measurement Unit; IMU) which is an important core of commercial superbike, first time any superbike is equipped with IMU (another is DUCATI 1299), the entire electronic control systems, IMU can monitor overall vehicle dynamics information, back to the ECU operations. IMU includes three gyroscopes provide pitch, roll and steering and other tri-axial information, three G sensors provide value around, up and down, left and right of acceleration. Through operations per second, 125 times, can learn R1 include dip, slide and dive speed. Data transfer via CAN to the ECU, the electronic control device to take this as a judgment of the degree of involvement.
6-axis inertial side volume elements. R1 IMU can be said that the electronic control system of the core, can be at different inclination, under dynamic, by changing the ignition and fuel injection, to achieve perfect control of the intervention according to the IMU information ECU, including the rear wheel MotoGP used in the slip control system (Slide Control System; SCS) and Traction Control System (Traction Control System; TCS) is at the IMU with a perfect actuation. Inclination sensing tracking system TCS TCS in general through the front and rear wheel speed sensors, the control ECU information to determine the degree of wheel slip and decide whether to get involved, but found the rear wheels lose traction, it will amend the throttle opening and ignition timing time. 2015 R1 IMU made by the body more dynamic information, so that TCS can automatically according to the vehicle inclination, to strengthen the accuracy of judgment. Vehicle under the straight and different inclination, its tire grip limit is not the same, after adding IMU information automatically when the vehicle is increased TCS rating dip, otherwise lower, will be able to reach the corners to erect one go full speed . Sliding Control System (Slide Control System; SCS) YAMAHA patented technology used in MotoGP, with the IMU also delegated to the new R1. SCS through the IMU signals, together with TCS to do with the control range of the rear wheel sliding around. This high level of electronic control systems has also increased in the field of riders riding fun.

Power mode (PWR) power mode from the original YAMAHA D-Mode evolution, provided to the rider, including the use of the track, including four different power modes.
YAMAHA riding control systems (Yamaha Ride Control system; YRC)
YRC electric vehicle rapid control interface provides four groups, allowing the rider for a quick selection. Meanwhile rider can set their own breakdown of electronic control settings for each packet, then be able to quickly choose their own frequently used settings.
Full colour TFT LCD meter
Facing the new R1 with a lot of electronic control information, YAMAHA chosen to large, full-colour LCD as a meter wide and 109mm of large screen clearly displays a variety of information. For clarity, the use of very small pixels, while the instrument has two display street and the track. In addition, the background can also choose white or black low, and with a light sensor control, according to the site will automatically adjust the brightness of ambient light. When displayed when the street stalls mode,the speed displayed in different colours now riders can immediately recognize the speed, in addition to including mileage, real-time fuel consumption, average fuel consumption, fuel usage, the most on the bottom and the lights are included TCS, SCS and other functions enabled status and power mode.
Under track mode displays useful features lap time, lap number and code tables, etc., to a more prominent position will be displayed in the right way, and speed display only the above data until 8,000rpm red line. At the same time in order to carry out post-match analysis, instrument will record every lap of the information, so the rider can be analysed after the ride.
YZF-R1 appearance from the YZR-M1, R1 also represents a new concept in order to track the performance as a repairer. Viewed from the side, YZF-R1 compact size, it is also born of M1 to contest its design, but also conducive to the Knights fixed or embedded in the body to reduce drag goggles. The YAMAHA been using overlapping style fairing design with a large area of exposed engine, are under air force calculation, considering the heat and the wind resistance of the best design and technology show a sense of R1.
The new R1 has changed the concept of conventional vehicle design, with “no headlights.” The concept is designed to allow commercial vehicles closer to the race vehicles. While its concealed LED positioning lights is to replace the general appearance of the vehicle headlight indicator for the whole bike, it has become an important element of the true representatives of the new face of R1, with real lighting, headlight just for lighting and set, the original arrangement position more hope the headlights is hidden. The new R1 LED positioning lights also represents a new generation of YAMAHA design elements, displayed in Milan, including the new TMAX 530 and MT-09 Tracer, can see the full sense of technology, with simple lines Draw eyes.
And M1 similar triangular platform design.
Overlapping fairing design with different colors of the exposed engine, showing a sense of technology.
To track performance as a goal, YAMAHA R1 has given us a new quite a shock, a lot of MotoGP decentralized electronic control systems, ultra-lightweight 199kg wet weight and 998cc four-cylinder steam engine crankshaft cross 200ps door. On this YAMAHA is published one litre four-cylinder is undoubtedly ready for track battle take out from a PS4 game. More importantly, with so much more, 2015 R1’s new bike price reported slightly more than a 2014 R1, which is about RM85,000 spread.
