The CBR’s Dual-Stage Fuel Injection system features two sets of injectors per cylinder for instantaneous high-rpm response, great low-rpm fuel metering, and clean running. Refined EFI settings and larger throttle bodies (48 mm vs 46 mm) make the engine even more manageable, with smoother throttle response particularly at smaller throttle openings.
Here’s what the Riding Mode Select System allows you to control. Power Selector (5 levels), which regulates engine power from peak output in all six gears at Level 1 to gentler power increase at Level 5 (all levels have the same throttle response on initial opening). Honda Selectable Torque Control (9 levels and off), which manages rear-wheel traction and front-wheel lift under acceleration. Selectable Engine Brake Control (3 levels), which regulates the amount of engine-braking force when you roll off the throttle. Öhlins Smart EC (3 manual and 3 automatic modes), which controls both the compression and rebound damping force of the semi-active Öhlins Electronic Control fork and shock.
Working in conjunction with the Throttle By Wire, fuel-injection and ignition systems, the SP’s quickshifter and Downshift Assist let you smoothly and quickly upshift or downshift without using the clutch. It even momentarily blips the throttle on downshifts, and you can select from three modes or off.
The titanium irregular-cross-section muffler helps shave overall weight, while also creating an unmistakable sound at wide open throttle. The exhaust supplier to the Repsol Honda MotoGP team was tasked to develop the prototype and produced an exquisite design with the 4-2-1 double-layer downpipes incorporating the exhaust valve within the first main pipe.
Light, powerful and easy to control. The 16 valve DOHC engine found in the CBR1000RR SP delivers class-leading power to weight ratio, making it stronger and lighter than its previous generation, while packing the latest technology derived from the groundbreaking Honda RC213V-S MotoGP™ machine. Powered by rich racing heritage and proven real world performance, the SP maintains its user-friendly character, specifically designed and dedicated to the concept of total control.
Engineered with extraordinary precision and designed with powerful purpose, the high horsepower engine revs harder and higher thanks to its 13 : 1 compression ratio, advanced cam timing and high revving 13,000 rpm redline. The pistons feature an optimized wall thickness and crown design, while the piston rings have Diamond Like Carbon (DLC) coating that improves sealing. Polished inlet and exhaust ports in the cylinder head and “gas-flowed” combustion chambers improve efficiency, and the intake funnels are “slash cut”, a design used in World Superbike.
From the use of a magnesium oil pan and ignition cover to a light Assist Slipper Clutch with light yet strong transmission gears, it all adds up to an engine that’s 2 kg (4.4 lbs) lighter than that found in its previous generation. This incredible attention to detail even included careful analysis on the precise shape and length of bolts, hoses and clamps.
The CBR1000RR SP features a cutting-edge electronic control system, allowing you to tailor its performance exactly the way you like it. Central to the system is the 5-axis Inertial Measurement Unit (IMU) gyro, which precisely measures what the machine is doing, in every plane. It works with the fuel-injection ECU, Throttle By Wire system—the first on an inline-four Honda—and even the ABS system to provide unparalleled ride control right at your fingertips.
The Riding Mode Select System makes it easy to program the CBR’s electronic controls for various types of riding situations. Accessed via the instrument panel and switches beside the left handgrip, RMSS lets you choose, on the fly, between five different combinations of electronic control: three modes offer preset combinations of engine power level, rear-wheel traction and wheelie control, engine braking strength, and suspension damping control, while two additional user settings allow you to customize combinations to your exact preferences.
