2017 Yamaha YZF-R1S

Chassis / Suspension

• FULL COLOR INSTRUMENTS: The R1S features a brilliant full-color, thin-film transistor LCD 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.
• DELTABOX® FRAME: The aluminum Deltabox® frame and magnesium subframe contribute to a light weight and compact chassis design. The aluminum frame is both strong and flexible, and uses the engine as a stressed member of the frame for optimal rigidity balance and fantastic cornering performance.
• FULL ADJUSTABLE KYB® FORK: The R1S features an advanced inverted KYB® front fork with 43mm inner tubes and a 4.7-inch stroke with full adjustability, for an exceptional balance of feedback and traction.
• 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 road.
• COMPACT CHASSIS DIMENSIONS: The YZF-R1S’ wheelbase is 10mm shorter than the 2014 YZF-R1, adding to cornering performance. However, the 2016 R1S retains a 40.5% ratio of swingarm length to wheelbase for superb handling.
• 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.
• POWERFUL, CONTROLLABLE BRAKES: The track developed and tested 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. ADVICS 4-piston radial mounted front calipers ride on big 320mm rotors for excellent stopping power.

Engine

• CUTTING-EDGE CROSSPLANE ENGINE: The R1S’ 998cc in-line 4-cylinder, crossplane crankshaft engine features steel fracture-split connecting rods and lightweight forged pistons. This race-derived engine delivers high horsepower and a strong pulse of linear torque.
• COMPACT STACKED TRANSMISSION: A 6-speed transmission is built to match the engine’s delivery and character for excellent response. The transmission "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.
• COMPACT EXHAUST SYSTEM: The 2016 R1S is equipped with a newly designed exhaust system crafted from titanium and stainless steel. Plus, the compact midship muffler contributes to mass centralization.
• ADVANCED CLUTCH: Assist and slipper clutch is used to give the rider more confident downshifts when entering corners aggressively, while still handling the torque of the R1S’ high-output inline-four motor.

Top Features

• CUTTING-EDGE MOTOGP ®-DERIVED CROSSPLANE CRANKSHAFT ENGINE: The 2016 YZF-R1S™ features a lightweight and compact crossplane-crankshaft, inline-four-cylinder, 998cc high output engine, producing excellent power and a strong pulse of linear torque for stunning performance.
• CLASS-LEADING ELECTRONICS PACKAGE: The YZF-R1S features an advanced MotoGP®-inspired electronics package: a suite of inter-related technologies, enabling the rider to enjoy the fullest range of performance with great comfort, control, and ease of operation.
• MOTOGP®-LEVEL CONTROLLABILITY: Featuring Yamaha’s six-axis Inertial Measurement Unit (IMU), the 2016 R1S represents the state-of-the-art in digital riding control, where all riders can experience total 3D controllability.
• INFORMED SYSTEMS: The IMU consists of a gyro sensor that measures pitch, roll, and yaw, as well as an accelerometer, or G-sensor, 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 2016 R1S is equipped with banking-sensitive Traction Control, as well as Slide Control, Wheel Lift Control, Launch Control, ABS, a Unified Braking System, and more. The all-new R1S gives street riders an amazing level of rider-adaptive performance.
• DELTABOX® FRAME: The 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.
• COMPACT EXHAUST SYSTEM: A midship exhaust system features a titanium muffler and is positioned low, in the middle of the chassis, for improved mass centralization.
• MOTOGP® STYLING: The styling on the R1S is shared with the YZF-R1M® and YZF-R1® and inspired by the YZR-M1™, purposely sculpted for maximum aerodynamic efficiency.
