1. Introduction
1992. And something new stunned the motorcycling world. Radical thinking from Honda
focused on the ratio between power and weight and the CBR900RR Fireblade arrived fully
formed at the perfect balance point between the two.
Physically smaller and much more agile than the larger capacity competition, its four­
cylinder engine also packed real punch. The Fireblade reset expectations of just what an
open­class sports bike should be, and what it could do in an era when outright horsepower
and straight­line speed had long held centre stage.
Over the following 25 years the Fireblade has seen many changes and been through many
evolutions – each underpinned by the concept of Total Control. Each generation has built
on the legacy of the original Fireblade, providing a superbly balanced package that works
evolutions – each underpinned by the concept of Total Control. Each generation has built
on the legacy of the original Fireblade, providing a superbly balanced package that works
incredibly well on track and, even more importantly, is both exhilarating and uniquely
rewarding to ride out on the open road.
The fact the Fireblade is so good when actually raced on real roads – at the Isle of Man TT,
for instance, where it is the most successful 1000cc machine ever with 23 wins to its
name – is testament to its speed, handling and ability to perform in the most testing and
extreme of ‘real world’ conditions.
Scroll to 2017 and there is a new CBR1000RR Fireblade. Three of them in fact: the
CBR1000RR Fireblade, CBR1000RR Fireblade SP and CBR1000RR Fireblade SP2. And
Honda’s engineers have remained true to the first principles of the original project – power
to weight – with the focus on handling, cornering and acceleration.
Thus, the benchmark CBR1000RR Fireblade is significantly lighter than the outgoing
model, makes more power and has a cutting edge electronics package that underpins the
project’s development concept of Next Stage Total Control.
It is everything that a Fireblade should be.

Mr M. Sato, Large Project Leader (LPL) 17YM CBR1000RR Fireblade
“All 1000cc sportsbikes are extraordinary examples of high performance engineering. But
for us, for our new Fireblade we want extraordinary to be the pleasure of handling and
controlling such a machine. Its true purpose ­ wherever it’s ridden ­ is to enjoy something
that is not normally experienced in everyday life, something that cannot be surpassed.
The very first CBR900RR remains a milestone in our history, and an inspiration we have
drawn on to radically reduce weight and increase power. And, to go to Next Stage Total
Control, we have added an electronic control system that is there to support the rider,
totally.
What then can our new Fireblade promise our customers? That is simple – the pure joy of
riding.”

2. Model Overview
Three factors are key to the essence of the new CBR1000RR Fireblade: less weight,
more power, and electronics to help the rider wherever and however they’re riding.
The new electronic control system provides constant, selectable and fine­tunable rider
support. Central to the system is the 5­axis Inertial Measurement Unit (IMU), which
measures exactly what the machine is doing, in every plane. It works the Honda
Selectable Torque Control system (HSTC) that precisely manages rear wheel traction via
the FI­ECU and Throttle By Wire (TBW). The new ABS braking (also managed by the IMU)
offers Rear Lift Control (RLC) and the ability for hard, safe trail braking into corners. Any
difference measured between the front and rear wheel speeds engages Wheelie Control,
depending on settings.
Three standard display modes – Street, Circuit and Mechanic – provide all the information
required for the rider relevant to the type of riding. The information displayed can be fine­
tuned and adjusted while riding by using the left hand switch gear and TFT liquid crystal
display, just as on the RC213V­S, Honda’s road going version of its RC213V MotoGP
machine.
While the electronic control is very much a new departure for the Fireblade, the other two
factors draw faithfully on the philosophy of the original 1992 machine: the optimal balance
of power and weight. Ninety percent of the main components have been changed in a
relentless search for incremental weight reduction in every area. The engine revs harder
and higher, with a much higher compression ratio and revised cam timing, and uses the
TBW (a first for an inline four­cylinder Honda) and Accelerator Position Sensor (APS) also
developed for use on the RC213V­S.
Bottom end torque and power are improved, with a significant increase in top­end power –
up 8kW to 141kW @ 13,000rpm and 3 modes of engine output character can be selected.
Thanks to the use of magnesium and careful assessment and lightening of individual parts
the engine also carries 2kg less. The new titanium exhaust muffler saves weight and aids
mass centralisation. Overall the Fireblade is a full 15kg lighter than the outgoing model,
with a wet weight of 196kg.
The twin­spar aluminium frame’s rigidity balance has been finely adjusted, and the
swingarm is stiffer to match. A new rear subframe is lighter, as are the redesigned wheels,

while new Tokico four­piston front brake calipers use high­performance track­ready brake
pads.
The Fireblade’s bodywork outlines an aggressive, functional minimalism, and the machine
is slimmer and much more compact. All lighting is LED and two stunning paint options –
Victory Red and Matt Ballistic Black Metallic – will be available.
3. Key Features
3.1 Chassis/Electronics
• Inertial Measurement Unit (IMU)
• Honda Selectable Torque Control (HSTC)
• New ABS
• Riding Mode Select System (RMSS)
The Fireblade’s new electronic control system provides several active features that many
riders will find useful. The new ABS allows extremely hard braking while maintaining rear
wheel contact with the ground, stopping the tendency for the rear of the machine to elevate
or ‘back in’ around the front. It uses the 2­axis acceleration information from the Inertial
Measurement Unit (IMU) and calculates the acceleration of the machine’s centre of gravity
in the lift direction and acceleration perpendicular to that, using the front wheel as the
grounding point.
The new ABS delivers smooth, effective braking into a corner. With information from the
IMU, 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. ABS delivers an extra
sense of security when braking hard on the road, and offers a performance edge in certain
conditions on the racetrack.
In isolation all the functions of the electronic control system – plus the HSTC’s wheelie
control – perform specific, individual tasks. When tied together, however and working
seamlessly as one they provide technological rider support that truly elevates the super
sports experience. Next Stage Total Control, indeed.
Like the RC213V­S the Fireblade uses a full­colour TFT liquid crystal dash to clearly
communicate information to the rider. It automatically adjusts to ambient light, with a
backlight of up to 1000 cd/m 2 luminescence and features 3 modes: Street, Circuit and
Mechanic ­ each with the information most relevant for that particular usage.
Street displays riding modes (1­3 and USER 1­2) plus the settings for each parameter – P
(power), T (HSTC) and EB (Selectable Engine Brake). Circuit adds in addition to Street
mode the lap time, number of laps and difference from the best lap. Mechanic displays the
digital tacho, gear position, grip angle, coolant temperature and battery voltage.
There are 3 preset riding Modes, Track (1), Winding (2) and Street (3) that offer different
combinations of HSTC, Engine Power and Engine Braking level. Riding mode 1 (Track)
gives full power, with linear throttle response, low HSTC and EB intervention. Mode 2
(Winding) controls output through first to third gear, with fairly moderate power increase,
medium HSTC and strong EB. Mode 3 (Street) controls output through first to fourth gear,
with moderate power increase, high HSTC and strong EB.
In the two USER modes all parameters can be combined and adjusted freely; riding
modes and HSTC can be changed while riding by using the up/down switch on the left
switch gear.
The Shift­Up indicator is a horizontal line of 5 white LEDs located at the top; when engine
speeds exceed user presets they go from solid to flashing. Displays include speedometer,
tachometer, gear position, coolant temperature, riding distance and twin trip meters.
The onboard computer calculates instantaneous and average fuel economy, trip fuel
consumption, average speed and time after last ignition, plus remaining fuel after reserve
light and distance to empty (when selected). This information is shown on the bottom right
of the screen.
In the upper display, middle right the rider can choose to see the Shift­Up indicator setting
speed, grip angle, battery voltage, calendar, or user­defined text.
Switching between modes is controlled by a mode switch on the right of the left hand
switchgear. Just above it is an up/down switch that manages and changes the information
displayed within the mode.
3.2 Chassis
• 196kg wet weight
• Showa 43mm Big Piston Forks (BPF) and Balance Free Rear (BFR) shock
• Adjusted rigidity balance for the frame
• Stiffer swingarm
• Lighter subframe
• New Tokico four­piston radial mount brake calipers
• Redesigned wheels
• Minimal and aggressively styled bodywork
As a machine now a full 15kg lighter – with a wet weight of 196kg –the Fireblade’s physical
handling has also been transformed. Rake and trail remain 23 °20’ / 96mm but the hollow
die­cast twin­spar aluminium frame’s rigidity balance has been significantly adjusted to
give even sweeter handling with outstanding steering response, feel and stability.
Thinned frame walls save 300g. While transverse rigidity is unchanged, the frame is 10%
more flexible in the torsional plane, which works to deliver a faster­reacting chassis. Yaw
moment of inertia has been reduced by 15%; roll moment of inertia by10%. The Honda
Electronic Steering Damper (HESD) unobtrusively maintains stability.
To complement the frame changes the aluminium Unit Pro­Link swingarm’s hybrid
structure has had the thickness of each section adjusted, saving approx. 300g while
maintaining transverse rigidity and increasing torsional rigidity.
The Showa 43mm BPF inverted telescopic fork with its large damping volume effectively
reduces hydraulic pressure generated under compression and extension. This results in
reduced play during the initial stroke and smoother damping, maximising tyre contact with
the tarmac. Spring preload and rebound/compression damping are fully adjustable.
The rear suspension features a fully adjustable Showa Balance Free Rear Cushion
(BFRC). Instead of a conventional single­tube layout, BFRC uses a double­tube design:
the damper case and an internal cylinder. The damper piston has no valves – instead the
damping force is generated as displaced oil passes through a separate damping
component.
This allows pressure changes within the shock to be smoothly controlled. And because
there are no small amounts of oil being used at high pressures, damping response and
reaction are improved, and damping force can function smoothly during load input.
Moreover, damping weight is generated consistently when switching from rebound to
there are no small amounts of oil being used at high pressures, damping response and
reaction are improved, and damping force can function smoothly during load input.
Moreover, damping weight is generated consistently when switching from rebound to
compression due to even pressure changes. The die­cast aluminium subframe too has been redesigned and its thinner construction is
at the same time highly rigid and 600g lighter – contributing to the concentration of mass
and thus neutral handling feel with improved agility. Wheelbase is 1405mm; seat height is
832mm.
New front Tokico four­piston opposed radial mounted brake calipers are highly rigid, 150g
lighter and do without hanger pins. Newly­developed high­mu (coefficient of friction) brake
pads are fitted – these have a greater performance parameter at higher temperatures than
standard pads. The aluminium wheels are a new five Y­shape design, saving approx.
100g. Tyre sizes are 120/70 R17 front and 190/50 R17 rear.
Minimal and dynamic are two words used to best describe the Fireblade’s new styling. The
design team wanted to create tightly compact proportions and the upper and middle fairing
surfaces have been reduced in size as far as possible. Forward tilting character lines
inject an aggressive attitude, with a focus on mechanical functionality, detail and quality of
finish.
24mm in width has been squeezed from the upper fairing. Airflow control from the flow
surfaces of the fairing, to the surface angle of the headlights and the contouring of their
side slits supports stability at speed. In a racing crouch the rider is tucked well out of the
airstream. In normal riding situations air pressure is evenly distributed on the rider’s
shoulders, back and sides.
18mm has been saved across the middle fairing and its ‘knuckles’ double as radiator
intake structures that pass discharged air around the outside, and underneath, the rider’s
legs. The knee grip area is 15mm per side slimmer, with the interface between tank cover
and the seat unit athletically accentuated.
All lighting is crisp LED, with the twin front headlights offering high/low beam on both sides.
Crowned with a sharply angled new logo the Fireblade will be available in two paint options:
Victory Red and Matt Ballistic Black.
3.3 Engine/Electronics
• Throttle By Wire (TBW)
• Accelerator Position Sensor (APS)
• Throttle By Wire (TBW)
• Accelerator Position Sensor (APS)
• Power Selector
• Inertial Measurement Unit (IMU)
• 9 level Honda Selectable Torque Control (HSTC)
• Wheelie Control
• Selectable Engine Brake (SEB)
• Riding Mode Select System (RMSS)
The 17YM Fireblade is the first inline four­cylinder engine from Honda to use Throttle by
Wire (TBW) control. Derived and developed from the system used by the RC213V­S, its
job is to put precise throttle control – and a very natural feel – in the rider’s right hand.
Heart of the system is a newly developed throttle grip Acceleration Position Sensor (APS)
integrated into the right handlebar switchgear, which itself neatly mounts the engine
start/stop switch – nothing more. APS converts movement of the grip into an electrical
signal sent to the ECU, that then transmits it as an actuator signal to the TBW motor,
achieving ideal throttle control relative to grip angle.
The return spring and other mechanisms inside the APS faithfully reproduce the initial play
and feel of a cable, with throttle load set specifically for the Fireblade. Throttle bore is
increased 2mm to 48mm (without increasing exterior width) and careful shaping of the
intake funnels adds to the linear throttle response.
The Power Selector can be accessed through the RMSS. It offers 5 levels of output
character: Level 1 give peak output in all six gears; Level 2 output is controlled in each gear
to achieve smooth throttle feel under acceleration or deceleration; Level 5 has the
strongest output control for most moderate throttle response. All levels have the same
throttle response on initial opening.
Riding Mode (1) uses Level 1 as its preset, drawing out the full performance of the engine.
Mode (2) uses Level 2, and is suitable for twisty roads and city environments, while Mode
(3) goes to Level 5 for maximum security. Individual rider preferences can also be input
manually through the USER 1 and 2 interface.
The Fireblade employs an enhanced version of the Honda Selectable Torque Control
(HSTC) used on the RC213V­S. It controls engine torque via two sensing methods – the
first uses wheel speed sensors to measure and compare front and rear wheel speeds.
When the FI­ECU detects rear wheel acceleration (and front wheel deceleration) it
reduces the TBW throttle position, and thus output, keeping the front wheel on the ground.
When the FI­ECU detects rear wheel acceleration (and front wheel deceleration) it
reduces the TBW throttle position, and thus output, keeping the front wheel on the ground.
Maximum application of the throttle is thus possible without fear of wheelies, with 3 levels
of Wheelie Control, plus off.
The second sensing function detects machine roll angle. The IMU located under the seat
detects rotational speed in the chassis’ roll and yaw directions, and acceleration in the
longitudinal, lateral and vertical directions. It then calculates roll angle to control engine
torque, maintaining rear wheel traction at the required level. The body roll calculation logic
used by the ECU uses the same attitude detection technologies developed for Honda’s
ASIMO humanoid robot, enabling the most precise calculation possible.
Nine intervention levels (plus off) are offered by HSTC to suit rider preferences, and the
Riding Modes USER 1 and 2 enable individual changes to be made while moving.
There is also a Selectable Engine Brake (SEB) system to change engine­braking
character to match rider preference and a range of conditions. Level 1 offers the highest
braking force, Level 3 the lowest. The preset Modes 1, 2 and 3 use recommended
settings, but through USER 1 and 2 can be set individually.
A Quickshifter with Downshift Assist system (as fitted to the CBR1000RR Fireblade SP1)
is available as an optional extra.
3.4 Engine
• 8kW power increase
• Revised valve lift and cam timing
• Magnesium covers and detail redesign saves 2kg
• 4­2­1 exhaust with titanium muffler
• Redesigned slipper clutch
Honda’s engineers exhaustively re­examined the Fireblade’s 999.8cc inline four­cylinder
engine to make it as light and powerful as possible. The result of the work is an extra 8kW,
the loss of 2kg and raised rev ceiling of 13,000rpm.
Peak power is 141kW @ 13,000rpm, with peak torque of 114Nm delivered @ 11,000rpm.
Bore and stroke remain 76 x 55mm but compression ratio is up from 12.3:1 to 13:1. This
is an engine in a very high state of tune and the crankshaft, valve train and transmission all
use higher specification materials than the previous design.
is an engine in a very high state of tune and the crankshaft, valve train and transmission all
use higher specification materials than the previous design.
The pistons feature an optimised wall thickness and a new crown design to raise the
compression; the surface finishing of the piston­ring grooves has also been modified to
improve sealing performance and efficiency. Valve lift and cam timing has been revised to
match the higher rpm and greater engine performance.
Power up is just one part of the Fireblade’s story – reduced weight is another. So every
part of the engine was scrutinised to see if it could be made lighter. All the engine covers
are redesigned (clutch cover is aluminium; the ignition cover magnesium) and the length of
the bolts, water hose and water hose bands have been reduced.
With a revised, rounded shape the radiator is 30mm narrower in overall width and 100g
lighter (including a 30cc reduction in water capacity). Using a new high­density core it
achieves identical heat dissipation and contributes to the slimmer frontal area of the fairing
cowls.
The assist slipper clutch is completely revised with a single die­cast pressure plate and
clutch centre, and offers reduced load at the lever. For downshifts the slipper functionality
remains the same as before but aluminium cam parts (instead of steel) save weight. The
gap between the accelerating and decelerating cams has also been optimised, again
improving lever feel when changing gear. All of the transmission gears have been pared
down to save weight.
The titanium irregular cross­section muffler is 2.8kg lighter and minimises the centre of
gravity change; it also creates an unmistakable sound tone from the exhaust on an open
throttle. The exhaust supplier to the Honda Repsol MotoGP team was asked to develop the
prototype and produced an exquisite design with the 4­2­1 double­skinned downpipes
incorporating the exhaust valve within the first main pipe.
