The machine is now a full 15kg lighter, with a wet weight of 195kg. And with an 8kW boost in power, the Fireblade’s physical handling has also been transformed. Rake and trail remain 23.3°/96mm, but the hollow die-cast twin-spar aluminium frame’s rigidity balance has been significantly adjusted to allow even sweeter handling with outstanding steering response, feel and stability.
Suspension and brakes
The Brembo four-piston monobloc radial-mount brake callipers use newly developed high-mu (coefficient of friction) brake pads – these have a greater performance parameter at higher temperatures than standard pads, and suit aggressive riding. The aluminium wheels feature a new five-Y-shape design, shaving about 100g of weight.
The Fireblade SP is the first Honda motorcycle to be equipped with Öhlins S-EC suspension front and rear: a 43mm NIX30 fork and TTX36 shock.
The Suspension Control Unit (SCU) receives roll rate, yaw rate and lean angle information from a 40g 5-axis (3-axis acceleration and 2-axis angular velocity) Bosch MM5.10 IMU gyro, located close to the machine’s centre of gravity. It also gathers wheel speed, engine rpm, brake input and throttle angle from the FI-ECU and, depending on the suspension mode selected by the rider, delivers optimal compression and damping force (adjusted via each step motor) during normal riding, plus hard acceleration, braking and cornering.
