2019 Yamaha YZF-R1

Chassis / Suspension

• DELTABOX® FRAME: The slim aluminum Deltabox® frame and magnesium subframe contribute to a light weight and compact chassis design, with overall geometry refined on racetracks around the world. The rigid motor mounts use the engine as a stressed member of the frame for optimal rigidity balance and great cornering performance on the race track.
• FULLY ADJUSTABLE KYB® FORK: The R1 features an advanced inverted KYB® front fork with 43mm inner tubes and a 4.7 inch stroke with full adjustability, for incredible front-end feel on the track. All adjustments are also made on the top of the fork legs, for simplified tuning.
• LINKAGE-TYPE KYB® SHOCK: The fully adjustable KYB® shock has a rear bottom link pivot position that is optimally placed to provide exceptional handling, and excellent transmission of engine torque to the track surface.
• ALUMINUM FUEL TANK: An aluminum 4.5 gallon fuel tank, weighing in at a full 3.5 pounds less than a comparable steel tank, further reduces overall weight and is sculpted to give riders a good lower body connection to the machine.
• POWERFUL, CONTROLLABLE BRAKES: The track developed racing ABS and Unified Braking System provide maximum braking performance. UBS inhibits unwanted rear-end motion during braking by activating the rear brake when the front brake is applied, with force distribution based on the bike’s attitude and lean angle. 4-piston radial mounted front calipers ride on big 320mm rotors for excellent stopping power.
• RACE-READY MAGNESIUM WHEELS: 10-spoke cast magnesium wheels significantly lower rotational mass compared to conventional aluminum alloy rims, reducing unsprung weight for quick direction changes and responsive handling.

Electronics

• MOTOGP®-LEVEL CONTROLLABILITY: Yamaha’s Inertial Measurement Unit (IMU) uses six axes of measurement: a gyro sensor that measures pitch, roll, and yaw, and an accelerometer that measures acceleration in the fore-aft, up-down, and right-left directions… all at a rate of 125 calculations per second. The IMU communicates with the ECU, which activates the technologies in Yamaha Ride Control (YRC): Power Mode, Traction Control System, Slide Control System, Launch Control System, Lift Control System and Quick Shift System with rev-matching. All these systems are adjustable and can be saved within four presets in the YRC system.
• RIDE-BY-WIRE FUELING: The ride-by-wire Yamaha Chip Controlled Throttle (YCC-T®) system senses the slightest throttle input by the rider and instantaneously calculates the ideal throttle valve opening, and then actuates the throttle valves to actively control intake volume. The R1 also features YCC-I® (Yamaha Chip Controlled Intake), a variable intake system that broadens the spread of power in across the entire rpm range.
• PWR MODE: Power Delivery Mode (PWR) lets the rider choose from four settings of throttle-valve response to best match their preferences and riding conditions, adjusting both engine response and overall power.
• LEAN ANGLE SENSITIVE TCS: The R1’s Traction Control System (TCS) reduces rear wheel spin when exiting corners, calculating differences in wheels speeds and in relation to lean angle. As lean angle increases, so does the amount of intervention, with ten separate settings (off and 1-9) enabling the rider to dial in the exact level of control needed.
• MOTOGP®-DEVELOPED SCS: Yamaha’s Slide Control System (SCS) is the first of its kind on a production motorcycle and comes directly from the YZR-M1® MotoGP® bike. It works in tandem with the IMU, so that if a slide is detected while accelerating during hard leaning conditions, the ECU will step in and control engine power to reduce the slide. This too can be adjusted by the rider, with four settings (1-3 and off).
• LIFT CONTROL SYSTEM: The R1’s Lift Control System (LIF) features progressive mapping to improve forward drive when the system intervenes. As before, the IMU detects the rate of chassis pitch and the ECU controls engine power to reduce the front wheel lift during acceleration, with four settings (1-3 and off) for fine-tuning.
• RACE START CONTROL: The R1’s Launch Control System (LCS) limits engine rpms to 10,000 even with wide open throttle. It maintains optimum engine output in conjunction with input from the TCS and LIF systems to maximize acceleration from a standing start. Three setting levels regulate the effect (1-2 and off).
• UP AND DOWN QUICK SHIFT SYSTEM: The Quick Shift System (QSS) on the YZF-R1 features downshifting capability as well as allowing full-throttle clutchless upshifting. On downshifts, the ECU matches engine speed on each downshift for instantaneous gear changes with minimal chassis disruption. The QSS can be adjusted with three settings (1-2 and off), as well as turning the downshift function on and off.
• FULL COLOR INSTRUMENTS: The R1 features a brilliant full-color, thin-film transistor (TFT) meter, including front brake pressure and fore/aft G-force readouts, giving the rider even more feedback from the machine. It features both street mode and a track mode that focuses on performance information, such as YRC settings, a zoomed-in view of the tachometer in the upper rpm range, a lap timer with best lap and last lap feature, gear position indicator and speed.

Engine

• CUTTING-EDGE CROSSPLANE ENGINE: The 998cc inline 4-cylinder, crossplane crankshaft engine features titanium fracture-split connecting rods, which are an industry first for a production motorcycle. The titanium alloy used to manufacture the connecting rods is around 60% lighter than steel, and this reduction in weight gives the R1 engine a responsive and potent character at high rpm. This stunning engine delivers extremely high horsepower and a strong pulse of linear torque.
• COMPACT STACKED TRANSMISSION: A 6-speed transmission features close-ratio gearing to best match the high-revving engine. The transmission also "stacks" the input/output shafts to centralize mass and to keep the overall engine size shorter front-to-back, which optimizes engine placement in the frame for outstanding weight balance.
• ROCKER-ARM VALVETRAIN: Advanced rocker-arm valve actuation uses the arm’s lever ratio to allow for larger valve lift while using lower cam lobes and reduced spring pressure, further boosting power.
• LIGHTWEIGHT ENGINE COMPONENTS: Lightweight magnesium covers and ultra-light aluminum fasteners are used across the engine to further reduce weight.
• TITANIUM EXHAUST SYSTEM: The R1 is equipped with an exhaust system manufactured primarily from lightweight titanium. The compact midship muffler also centralizes mass low in the frame and as close to the center of the machine as possible, improving overall handling.
• ADVANCED CLUTCH: Yamaha’s assist and slipper clutch is used to give the rider more confident downshifts when entering corners aggressively, while still smoothly handling the torque of the R1’s high-output inline-four motor.

Other Features

• MOTOGP® STYLING: Dynamic YZR-M1 styling creates a more compact profile with improved aerodynamics, getting you closer to MotoGP® than any other production motorcycle available today.
• ALL-LED LIGHTING: LED headlights are both lightweight and compact, allowing for a more streamlined design of the front face. LED front turn signals are integrated into the mirrors for improved aerodynamics, while an LED tail light is stylish and highly visible.
• FACTORY LEVEL TELEMETRY: Available as an option is the Yamaha-exclusive Communication Control Unit. The CCU allows riders to communicate with the vehicle via Wi-Fi through Yamaha’s exclusive Y-TRAC smartphone and tablet app. The system is comprised of the CCU and GPS antenna, running data can be recorded via a data logger, with course mapping and automatic lap timing managed by GPS. This data can then be wirelessly downloaded to the Android® or Apple® iOS® app where it can be analyzed. Changes to settings can be made via the Yamaha Ride Control (YRC) Setting app and then uploaded back to the R1.
