From a clean sheet, Honda and HRC’s development engineers set to work creating a new inline four-cylinder engine for the CBR1000RR-R Fireblade. It’s 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.
CBR1000RR R Fireblade - Overview
A ram-air duct in the front fairing feeds through the headstock directly into the airbox. The 4-2-1 exhaust downpipes are ovalized and the end-can has been developed in conjunction with Akrapovic.
The result? The CBR1000RR-R engine delivers 113Nm @ 12,500rpm and makes peak power of 160Kw @ 14,500rpm.
Throttle By Wire has been enhanced for improved feel and three default riding modes feature options to change Power, Engine Brake, Wheelie Control and the optimised Honda Selectable Torque Control (HSTC). The electronics package also now includes adjustable Start Mode.
A totally new aluminium diamond frame uses the rear of the engine as the upper shock mount; the swingarm is longer and based on the RC213V-S design. The rigidity balance, weight distribution and steering geometry have been carefully adjusted for the increased engine output, in terms of front and rear grip levels, and feel for both.
Showa’s 43mm Big Piston Fork (BPF) is matched to a Showa Balance Free Rear Cushion Light (BFRC-L). The front discs are larger in diameter and worked by new Nissin four-piston calipers while the ABS is adjustable for track riding. The rear tyre is now sized 200/55-ZR17.
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 new rod-type 3-level Honda Electronic Steering Damper (HESD).
Honda’s RC213V MotoGP machine has leant some of its slippery aerodynamics to the CBR1000RR-R, including winglets to increase downforce and improve braking stability. The riding position is also much more compact.
The fully customisable 5-inch TFT display offers intuitive control operated via a simplified four-way switch on the left handlebar. Honda’s Smart Key system adds convenience.
