cool for a 10-year-old bike.
“The CBR has a flapper valve in its airbox, which can
be removed for a bit of low-end gain, but there is very
little point in removing the air bleed system. Where a
Power Commander can get a misreading due to the
fresh air introduced into the exhaust by this system,
when re-flashing the ECU we can simply turn it off so it
doesn’t hamper anything. Also, if you fit a full system,
we can turn off the Fi fault code caused by the missing
exhaust valve or O2 sensor. It’s also quite a good idea to
lower the point at which the radiator fan kicks in, just to
keep the bike running cooler.
“Likesomanymodernbikes,thefirstpart of the

ride quality. Finally, if you don’t like the standard
electronic steering damper, we can turn it off via the
ECU and you can fit a conventional Öhlins unit instead.
And the best bit is that for about £360 you can add all
these extra features to your bike. With a full system and
aftermarket air filter – which is what you booked the
dyno work for in the first place – you can also unleash
a 10bhp power gain. Result.”

“There are loads of parts you can add for
relatively little money that bring it up to the
spec of the latest supersport bike. The first
thing owners do is upgrade the brakes. If
you are riding on the road, Brembo do some
excellent pads, but when it comes to
trackdays, EBC GPFAX pads are staggering.
Their performance is consistent regardless of
their temperature. Combine GPFAX pads with
some Brembo Serie Oro discs and braided lines and
you have a set-up that is more than a match for
anything else out there.
“When it comes to electronics, gear indicators are
always popular, and a lot of owners fit
the Bazzaz Z-Fi fuel control
module as it adds traction
control and a quickshifter
for £606. We sell other
gizmos such as a speedo
healer and exhaust servo
eliminator, but generally
it is the Bazzaz that
riders buy.
“We don’t sell as many
exhausts for the CBR as
we used to, as so many
used machines already have
aftermarket cans fitted. The
same is true for rearsets and stubby
levers. Crash protection is always popular, as are taller
screens because the OE Honda unit is very small.
“I’m surprised by how many Nitron shocks we sell for
the CBR, but owners say the spring is too firm on the OE
shock and there are big benefits when it comes to fitting
a bespoke shock. Finally, although they are expensive, I
can’t recommend carbon wheels highly enough. If you
are into track riding they not only make the bike handle
better, but also reduce the effort required to turn,
meaning you get far less fatigued during the day.”
Next month: riumph’s slice of British beef, the T
Speed Triple 1050.

STANDARD VS REMAPPED

ECU HACK PAYS DIVIDENDS
As this dyno from Dave Wood Racing shows, remapping the CBR600RR not only
smoothes out the power curve, but also adds power everywhere, especially north
of 8500rpm. Dips in the torque delivery are exceptionally well ironed out, too.
