The Fireblade’s inline four-cylinder engine delivers 112Nm @ 12,500rpm and makes peak power of 160Kw @ 14,500rpm.
Updates for 2022 Honda CBR1000RR R Fireblade centre around upping mid-corner drive and acceleration. Firstly, the rear sprocket goes from 40 to 43 teeth, improving acceleration through the gears in the mid-range while maintaining high-rpm output.
Both airbox and intake funnels have been re-shaped to smooth flow. The intake ports have been adjusted to increase airflow velocity while exhaust flow into the catalyser (and the catalyser itself) has also been optimised.
Throttle By Wire (TBW) spring load has been reduced, for improved linearity and response on opening. Using extensive feedback from racers around the world – including Honda’s HRC World SBK team – Honda Selectable Torque Control (HSTC) has been refined to offer the rider the power, grip level and feel they want, and to match the increased drive.
As before, three default riding modes cover most conditions with options to fully adjust Power, Engine Brake, Wheelie Control and HSTC. The electronics package also includes adjustable Start Mode.
The engine uses a compact, short-stroke layout – sharing the bore and stroke of the RC213V – and features a semi-cam gear train, finger-follower rocker arms, titanium con-rods, RC213V-S internal friction reduction technologies, piston jets with check ball system and a built-in bottom bypass passage for the cylinder water jacket. A ram-air duct in the front fairing feeds directly through the headstock. The 4-2-1 exhaust downpipes are ovalized and the end-can was developed in conjunction with Akrapovič.
An aluminium diamond frame uses the rear of the engine as the upper shock mount while the swingarm is based on the RC213V-S design. The rigidity balance, weight distribution and steering geometry are carefully adjusted to exploit the engine’s output, in terms of front and rear grip levels, and feel for both. A six-axis Inertial Measurement Unit (IMU) provides accurate 3D estimation of riding dynamics and provides input to manage all of the electronic systems. It also controls the rod-type 3-level Honda Electronic Steering Damper (HESD).
Showa’s 43mm Big Piston Fork (BPF) is matched to a Showa Balance Free Rear Cushion Lite (BFRC-L). The front discs are worked by Nissin four-piston calipers, which have received revised piston material and surface treatment improving heat management. The ABS is adjustable for track riding.
Honda’s RC213V MotoGP machine has leant some of its slippery aerodynamics to the Fireblade, including winglets to increase downforce and improve braking stability. The riding position is also very compact. A fully customisable 5-inch TFT display offers intuitive control via a four-way switch on the left handlebar. Honda’s Smart Key system adds convenience.
The CBR1000RR-R Fireblade will be available in the beautiful Grand Prix Red colour scheme introduced for the 20YM redesign, now featuring a white front ‘number board’.
