Today a new base Honda CBR1000RR debut in Italy. High-end Ohlins and Brembo components from the SP is exchange for less expensive Showa and Tokico piece.

Otherwise, much stays the same, including a plethora of motor mods, ride-by-wire throttles and IMU-based electronic rider aids. Even the SP’s titanium fuel tank is carried over to the regular RR, and its titanium muffler is said to be 6.2 lbs lighter than previous. Some 4.4 lbs was also shaved from the weight of the engine. It adds up to a CBR1000RR a purported 33 lbs lighter than the last generation, for a fueled wet weight of 432 lbs.

Engine has higher compression ratio and modified CAM timing, Honda said that the speed range of the power at the end of two, put forward an additional 10.7 horsepower (189 horsepower at 13000 RPM), the top may make CBR fans buzzing. It supposedly power-to-weight ratio increased by 14%.
From Honda news materials collected by other things including modified ski clutch, joint in the six-speed box gear reduction.
Tokico four-piston front brake calipers use high-performance track-ready brake pads, and are controlled by a new Lean-Sensitive ABS system that uses an IMU.
“With information from the IMU,” says Honda, “plus front- and rear-wheel speed sensors, the ABS modulator controls braking force according to lean angle, even when emergency braking. But it also allows for hard trail braking by using two parameters (deceleration derived from wheel speed and front/rear slip rates) plus lean angle to vary the threshold of ABS intervention.”
Suite Electronics… Honda’s first inline four-cylinder engine to employ Throttle by Wire (TBW) – derived from the system used by the RC213V-S – using an Acceleration Position Sensor (APS) integrated into the right handlebar switchgear to convert movement of the grip into an electrical signal sent to the ECU. “The return spring and other mechanisms inside the APS,” says Honda, “faithfully reproduce the initial play and feel of a cable, with throttle load set specifically for the Fireblade.”
Five levels of power are selectable, from Level 1’s peak output in all six gears to Level 5’s “most moderate throttle response for maximum security.”
Honda optional torque control (HSTC) by two methods of testing the control engine torque – used to compare the front wheel and rear wheel speed of the wheel speed sensor, and by testing the chassis roll and yaw direction on the bottom of the rotating speed of IMU and longitudinal acceleration, lateral and vertical direction. There are nine intervention level and shut down.
A Selectable Engine Brake (SEB) system provides three engine-braking settings. A Quickshifter with Downshift Assist system (like the one on the CBR1000RR SP1) is available as an option. You’ll access and play with all that through a full-color TFT liquid-crystal dash (again, like the RC213V-S’s) which automatically adjusts to ambient light, and offers three modes: Street, Circuit and Mechanic.
Three preset riding Modes, Track (1), Winding Road (2) and Street (3) provide different combinations of HSTC Honda Selectable Torque Control), Engine Power and Engine Braking level. Two additional User modes let riders add custom programs.
Rake and track keep 23 ° 20 ‘/ 96 mm, but the stiffness of the hollow aluminum die-casting wings beam frame balance has the significant adjustment to give even more sweet has outstanding steering response processing, shooting and stability “Honda says 15 kg (33 lb) weight reduction has been” transform “Fireblade processing.
Honda says the frame is 10% more flexible in the torsional plane, which works to deliver a faster-reacting chassis. Yaw moment of inertia has been reduced by 15%; roll moment of inertia by10%. The aluminum Unit Pro-Link swingarm is now about 10.6 ounces lighter, “while maintaining transverse rigidity and increasing torsional rigidity.”
Front suspension by the fully adjustable 43 mm showa large piston fork; After the suspension is equipped with fully adjustable Showa Balance Free Rear as (BFRC), the latest double tube valve design. Aluminum wheel is a new 5 Y design, save some. 100 g (3.5 oz). Tire size 120/70 – R17 before and after 190/50 – R17.
It’s all a very highly evolved motorcycle, adorned with narrower ergos and crisp LED lighting, yours in Victory Red or Matt Ballistic Black.
