2027 Honda CBR1000RR-R Fireblade SP

Engineering

• LONGER SWINGARM: A specially engineered long swingarm, with precisely calibrated horizontal and vertical rigidity, enhances traction during corner entry and provides superior grip during hard acceleration.
• SHORTER ENGINE: The compact front-to-back engine design optimizes the bike's overall profile, giving our designers increased flexibility in positioning the powerplant within the chassis.
• COMPACT OVERALL CHASSIS: The wheelbase measures 57 inches, allowing for super-responsive handling. The traction-producing swingarm accounts for 24.5 inches of that length, and the crankshaft centerline is positioned for optimal balance.
• TWIN-SPAR FRAME: A lightweight aluminum frame with two-millimeter-thick wall sections fine-tunes both vertical and torsional rigidity for better feel and performance.

Handling

• ÖHLINS SMART SUSPENSION: Öhlins manufactures the electronically controlled third-generation NPX fork. It uses a pressurized damping system to both stabilize force and improve bump absorption.
• BREMBO BRAKES: The front brakes feature 330mm discs paired with radial-mount Brembo Stylema R calipers, and the rear caliper is the same model used in MotoGP. Additionally, Brembo provides both brake master cylinders and the front brake lever, offering the rider a comprehensive braking system.

Performance

• 1000CC INLINE FOUR: Featuring a bore and stroke of 81mm x 48.5mm, the engine design is inspired by Honda’s RC213V MotoGP race bike and draws on our extensive track-gained experience with cylinder filling and combustion.
• TITANIUM MUFFLER: Developed jointly with Akrapovič, the muffler is made of titanium for lightweight construction and improved mass centralization. A special valve helps boost torque at lower revs and increase horsepower at higher rpm.
• INTAKE-PORT SHAPE: We shaped the intake ports to increase charge velocity, resulting in improved midrange performance—a real benefit on corner exit.
• AIRBOX SHAPE: The design of the airbox, combined with the shape of the intake port, enhances the engine's midrange power.
• NARROWER INTAKE-SIDE VALVE ANGLE: A super-narrow 9-degree intake valve angle delivers high ventilation efficiency in the intake port, resulting in power output across the entire rpm range.
• LARGE THROTTLE BODIES: The throttle bore diameter measures a huge 52mm. The oval cross-section inside the throttle body streamlines airflow from the throttle butterfly to the twin intake valves in the head, reducing intake air pressure drop.
• TITANIUM RODS: By eliminating the separate fastening nut and utilizing a titanium design inspired by the renowned RC213V-S rod, we've achieved a staggering 50% weight reduction compared to steel rods.
• SEMI-CAM GEAR CHAIN: The cam drive features a compact chain design. A gear on the crank engages an intermediary gear, which then drives the cam chain, resulting in a shorter overall chain run.
• FORGED ALUMINUM PISTONS: You need a light piston to make high revs. To that end, the pistons are forged out of A2618 aluminum, the same material used in the RC213V. Each piston is approximately five percent lighter than a standard CBR1000RR piston, despite having a larger bore.
• BUILT-IN BOTTOM BYPASS COOLING: Our innovative built-in bottom bypass cooling system directs cooling water differently around the top and bottom of the cylinder. The top requires more cooling, while the bottom needs less. This technology eliminates the need for an external hose outside the cylinder block. Consequently, the temperature difference across the cylinder bores is minimized.
• COMPACT STARTER LAYOUT: Normally, a motorcycle engine is started by rotating the crankshaft. However, on the Fireblade SP, the starter engages the clutch main shaft, allowing the engine to be as compact as possible.

Style

• AERODYNAMIC WINGLETS: Aerodynamic winglets generate significant downforce, particularly beneficial for track use. The two large wings installed at the upper front edges of the side fairings increase traction on corner exit and improve front-tire grip under braking.

Technology

• HONDA SELECTABLE TORQUE CONTROL: Honda Selectable Torque Control (HSTC) ensures you stay in control while riding. The system automatically adjusts engine power to optimize torque at the rear wheel, reducing rear-wheel slip. You have the option to select from five power curves, ten torque levels, three engine-braking levels, and three levels of wheelie control.
• THROTTLE BY WIRE: Our throttle-by-wire system enhances throttle response, particularly during initial engagement, and also enables the integration of our ride mode system.
• FULL-COLOR TFT SCREEN GAUGES: A large, high-resolution TFT display offers customization of essential information, including the speedometer, tachometer, gear position, fuel level, engine temperature, riding modes, and more.
• QUICK SHIFTER: The quick shifter allows for clutchless, full-throttle, seamless gear changes in both directions for uninterrupted power delivery. It also reduces shift shock and minimizes engine wear.
• SMART KEY: Removing the conventional keyed ignition enhances convenience while allowing us to optimize the intake ducting for improved airflow. Plus, the top triple clamp has that trick, race-bike look.
