Long before you start to tip the Fireblade into a corner, its high-tech brain is already making any necessary calculations.
The 5-axis (3-axis acceleration, 2-axis angular velocity) Inertial Measurement Unit (IMU), located close to the machine’s centre of gravity is the bike’s nerve centre, constantly interpreting roll, yaw and lean angle.
Information on wheel speed, engine rpm, plus brake and throttle position, are also gathered from the other sensors and, on the SP and SP2—depending on the suspension mode selected by the rider-optimal compression and rebound damping force are then applied, for total suspension control at different speeds.
Rear Lift Control (RLC) helps keep the back wheel under control when braking hard and late into corners. The ABS is tuned for track use, and manages braking force into corners with reduced intervention the high speeds generated on a racetrack.
You and the machine are always in control, at any angle.
The ABS works on the way into a corner, increasing confidence when you’re going for a hot lap—and it helps the professionals, too.
Shared with the Fireblade, the Fireblade SP’s DOHC inline four-cylinder engine has the same 141kW peak power output, 114Nm peak torque, magnesium parts, slipper clutch and titanium exhaust muffler. But it also has a Quickshifter fitted as standard for clutchless upshifts, plus Downshift Assist, which allows clutchless downshifts with an autoblipper function.
SP2. Made to race
As a homologation special, the SP2’s engine is ready to receive HRC race kit parts. Also integrated during its build are electronics that open up extra levels of functionality and performance specific to the track. The HRC Launch Control can be set between 6-12,000rpm, and there’s also a Pit Lane speed limiter function.
The Fireblade’s engine is a four-cylinder masterpiece that draws on RC213V engineering and electronics.
Shaped for improved ground clearance, the titanium exhaust muffler saves weight and aids mass centralisation.
The output characteristics of the engine, handling response of the chassis and—on the SP and SP2—the Öhlins suspension are electronically managed and constantly adjust as you ride. The RMSS features 3 pre-set options, FAST, FUN and SAFE and are selected by flicking a switch on the left handlebar.
Delivers full, linear power with smooth throttle response, low HSTC intervention and Engine Brake control while introducing high damping force adjustment.
Power output is managed through the first three gears with medium HSTC, Engine Brake and suspension damping force adjustment.
Control engine performance from first through to fourth gear, with high HSTC input providing improved rear wheel traction alongside increased Engine Brake. The suspension adjusts to provide low damping force.
There are two USER Modes, making five riding modes in total. When selected mode 1, 2 and 3 can be programmed independently to suit the rider’s style, body weight, track layout and conditions. Some settings can also be switched off completely.
The Fireblade SP and SP2 are the first Honda motorcycles to be equipped with Öhlins Step motor-type Electronic Control (S-EC) suspension, a 43mm NIX30 inverted front fork and TTX36 rear shock. Depending on the suspension mode selected by the rider, the system delivers optimal feedback—which automatically adjusts via the Suspension Control Unit (SCU)—for normal road-riding conditions as well as the hard acceleration, braking and cornering forces generated on a racetrack.
The aluminium Unit Pro-Link swingarm’s hybrid structure is incredibly rigid while the gas-charged Öhlins TTX36 rear shock offers top-shelf quality, full adjustability and a 60mm stroke.
There’s plenty of feedback and feel coming your way from the Öhlins 43mm NIX30 inverted front fork. The Fireblade SP2 is also equipped with gold Marchesini wheels and four-piston Brembo monobloc calipers.
