MotoGP™ DNA
The CBR1000RR-R Fireblade SP has been created from the ground up with heavy input from the HRC MotoGP™ development program. Engine and chassis technology lean heavily on that of the RC213V-S ‘Street legal MotoGP™ machine’, with aerodynamics drawn from the RC213V MotoGP™ bike. Power delivery, handling and aerodynamics are all targeted toward outright track performance. |
Cutting Edge Performance
To make an amazing sport motorcycle even better, Honda engineers looked at every component in the inline-four engine with the aim of squeezing out a little more performance here, a little better rider control there, and a little less weight overall. We believe this is the best Fireblade we’ve ever made. |
Valvetrain Upgrades
More torque at low revs means better drive out of corners, so our engineers focused on the shape of the piston and connecting rod, while optimizing valve timing to help prioritize combustion consistency and thereby exhaust efficiency at lower revs. The bridged-box design of the piston uses a reinforcing structure between the skirt and the wrist-pin bosses that helps enable a high redline. Big torque down low, huge power up top. A winning formula. |
Twin DSFI Motors
For ultimate control of the intake charge, the Dual Stage Fuel Injection system now employs two motors to open and close the throttle-body valves. One motor controls the intakes for cylinders 1 and 2, the other controls the intakes for cylinders 3 and 4. This allows finer control of the fuel-injection system, and thereby smoother transition between acceleration and deceleration. In other words, a more rider-friendly powerband. |
Reduced Weight – Better Response
Even while boosting power, engineers still managed to reduce the weight of the RR-R SP’s engine. A new crankshaft shaves 450 grams while also reducing inertial mass by 8.8%, and the connecting rods and crankcase have also dropped weight. Less weight in reciprocating components allows revs to build faster and throttle response to be quicker. |
Reduced Friction
To help reduce internal friction and improve durability, the cam lobes are coated in Diamond Like Carbon (DLC) – similar to the RC213V-S. The cylinders also feature a built-in bottom bypass that circulates cool water from the radiator into the main water jacket, while the area below uses non-cooled water. The outcome is a lower, more even temperature at all points across the cylinder bores for less distortion and friction. |
Ram-Air Induction
A ram-air duct located in the front fairing tip feeds through the headstock, around the steering stem and into the airbox. The opening area of this system is equivalent to that of the RC213V MotoGP™ machine and its design provides high ram pressure in a stable manner at a wide range of speeds. |
Akrapovic Exhaust
The 4-2-1 exhaust downpipes have optimized diameters and oval cross section to improve gas flow. The smaller, lightweight titanium exhaust muffler was developed in conjunction with Akrapovic, to help deliver both low-RPM torque and high-RPM power; a valve stopper helps stop exhaust-gas leak when closed while also reducing noise, allowing the mufflers total internal volume to be reduced by 38%. |
Throttle By Wire
Throttle By Wire (TBW) ensures fast response through a range of part-throttle applications – such as gradual opening as you exit a corner – thereby minimizing any delay in torque delivery. It's derived from the RC213V-S to provide more linear delivery and puts precise throttle control – and a natural feel – in a rider's right hand. |
Riding Modes
Three default riding modes feature options to change the engine’s output and character. Power (P), Engine Brake (EB) and Wheelie (W) control can all be adjusted within the modes. The RR-R SP is also equipped with Start Mode for optimum race starts — It limits engine revs at 6,000, 7,000, 8,000 or 9,000 RPM set-points even with a wide-open throttle, helping you focus on clutch release (and lights) alone. As well, a quickshifter is fitted as standard, with performance optimized for racing and reliability. |
Wheelie Control
Wheelie control uses information gathered by the IMU on pitch angle, along with front and rear wheel speed sensors to maintain torque and manage any front wheel lift without sacrificing forward drive. |
Honda Selectable Torque Control
Honda Selectable Torque Control (HSTC) adjusts through nine levels and off. HSTC has been optimized for the RR-R SP and adds slip-rate control to moderate rapid wheel spin. In conjunction with the existing outright slip control, HSTC is smooth in operation while helping deliver added rider confidence. |
