2019 Yamaha YZF-R1

Top Features

• MotoGP®-Derived Crossplane Crankshaft Superbike
  The YZF-R1® features a lightweight and compact crossplane crankshaft, inline-four-cylinder, 998cc high output engine. Featuring titanium fracture-split connecting rods, an offset cylinder block and magnesium covers, the motor delivers extremely high horsepower and a strong pulse of linear torque for outstanding performance, all wrapped in aerodynamic MotoGP®-style bodywork.
• Class-Leading Electronics Package
  The YZF-R1 features the most advanced electronics package ever offered on a supersport machine, with a full suite of interrelated technologies that enable the rider to enjoy the fullest range of performance with greater comfort, control, and ease of operation than ever before.
• MotoGP®-Level Controllability
  The YZF-R1 pioneered the use of the first six-axis Inertial Measurement Unit (IMU) ever offered on a street-going motorcycle. The IMU consists of a gyro sensor that measures pitch, roll, and yaw, as well as an accelerometer that measures acceleration in the fore-aft, up- down, and right-left directions… all at a rate of 125 calculations per second. By calculating each signal, the IMU finds the precise vehicle position and movement, and communicates it to the ECU, enabling it to control the bike’s systems.
• Digital Rider Aids
  The YZF-R1 is fully equipped with banking-sensitive Traction Control and unified ABS, as well as Slide Control, Launch Control, and more. The Quick Shift System provides both up and downshifting ability, automatically matching engine speed on downshifts for rapid clutchless shifts in either direction. The Wheel Lift Control system smoothly intervenes for maximum forward drive.
• Deltabox® Chassis
  Advanced aluminum Deltabox® frame uses the engine as a stressed member of the chassis and is designed to provide optimum longitudinal, lateral and torsional rigidity balance. Fully adjustable suspension front and rear provides exceptional road-holding and tuneability.

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.

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.

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.

Additional Features
