Honda CBR1000RR-R
Fireblade SP features
an all-new, short-stroke
inline four-cylinder 999cc
engine with the same bore
and stroke as the RC213V
(81 x 48.5mm). Honda
touts that the new RR-R SP
puts out 215 horsepower at
14,500 RPM and 83 lb-ft of
torque at 12,500 rpm. With
a wet weight of 443 pounds,
the new RR-R is 12 pounds
heavier than the outgoing
2019 model.
While there is a slight
weight increase, it's over-
shadowed by a 26-horse-
power increase over the
2019 model. This has been
achieved with a new top
end, finger followers, DLC
(Diamond Like Coating)
cams and a shorter cam
chain. The bottom end of the
engine sees some redesign
as well, with connector rods
made of forged aluminum,
Beryllium coated tips and
Teflon coated piston skirts.
The exhaust system was
redesigned to meet strict
Euro-5 standards. Honda
engineering teams devised
an intricate liquid-cooling
system.
The SP has an RCV-style
30.5mm longer swingarm
that extends the RR-R SP
wheelbase to 48mm. Ad-
ditionally, the crank position
has been moved further and
higher from the front wheel,
which will increase the bike's
center of gravity but also im-
prove high-speed cornering.
The suspension on the
new RR-R SP includes fully
electric Ohlins components
front and back. Honda
continues to develop its
fully customizable electronic
riding suite which includes
three levels of electric steer-
ing dampening (HESD), a
new six-axis IMU, traction
control, cornering ABS,
wheelie control and engine.
An up/down quick shifter
also come standard.
The SP includes MotoGP-
inspired winglets which
contribute to an increase
in downforce and improve
braking stability. Addition-
ally, there are three vertically
stacked internal fairing wings
to channel air and increase
stability. Further aerodynam-
ic advancements include
lowering the tank cover
45mm and redesigned the
lower and rear fairings. CN
