Brakes
A1. Why are 6 piston calipers better than 4 piston calipers?
The main benefit of six piston calipers
over four piston calipers is that the use of a longer
narrower pad track allows a lighter disc of the same
diameter to be used, reducing unsprung weight and gyroscopic
effects. The increased number of pistons also provides
a smoother braking action and a more even distribution
of heat over the disc surface, minimising disc warping.

Brakes
A2. Why don’t you sell wavy discs?
Because ISR don’t make them and also
because there are a number of practical reasons why
I personally don’t like them: All those edges eat brake
pads and shorten their life to an unacceptable level.
I don’t relish the prospect of replacing pads after
every race meeting. Wavy discs have a smaller surface
area in contact with the pad material which is not a
good thing in my book. Because there is so little metal
doing so much work, there could be heat transfer problems
(such as the disc turning blue) or the brake fluid heating
up beyond it's boiling point causing brake fade. The
only benefit that I can see they have is that they have
a reduced gyroscopic effect on the wheel which means
you can turn into corners quicker. However, you can
do that by using a narrower pad track on a normal brake
disc. Or get better wheels. Or race carcass tyres.

Brakes
A3. I've upgraded my calipers but am not seeing increased
braking performance. Why?
If you have upgraded your calipers,
e.g. from 4 piston to 6 piston, or from 2 piston to
4 or 6 piston and you don't think that you are seeing
the improved braking performance that you expected,
it may be that your master cylinder is not powerful
enough to cope with the increased pad area. This may
be especially apparent on Supermoto bikes where the
standard master cylinder bore is around 11mm. For a
single 4 or 6 piston caliper you should have a master
cylinder with a bore of at least 14mm. For a pair of
4 or 6 piston calipers, you should have a master cylinder
with a bore of at least 17.5mm The best thing you can
do is get a master cylinder with adjustable ratio, which
means that you can effectively adjust the bore size
to control the amount of fluid being moved and hence
the braking power. So, you can adjust the power to suit
your riding style, and to suit the track you are racing
on.

Brakes
A4. Where can I get replacement pads for ISR calipers
from?
The 6 piston montoblock and vented calipers are supplied
with DC pads, which is a carbon based racing compound.
The small 6 piston, 4 piston and the 2 piston monoblock
calipers are all supplied with RQ pads. For the other
calipers, you need to tell us whether you are using
it on the front or rear of the bike and we will include
the relevant pads. Click here for more information on
the pad compounds.

A5. Where can I get replacement pads for ISR calipers
from?
Both EBC and SBS do a range of different
pad compounds for all ISR calipers. Alternatively, we
have pads in stock for next day delivery. Click

Brakes
A6. Do I need a remote or integral reservoir on my front
master cylinder?
In most cases you will just replace
like for like for simplicity. However, it's worth bearing
in mind the benefits and drawbacks of each so you can
make a decision based on your situation or requirements.
Integral reservoirs have an internal bladder which separates
air from the brake fluid, so if you drop the bike, air
is prevented from getting into the brake system, meaning
that you will not experience a unexpected loss of power.
Integral reservoir master cylinders are therefore recommended
for Supermoto. Most sport bikes use remote reservoir
master cylinders and clutches. It is unlikely that these
types of bikes will be dropped, and therefore the drawback
of air being trapped in the pipe between the reservoir
and the lever causing a loss of efficiency is outweighed
by the benefits of the extra volume of fluid usually
required by large calipers throughout the life of the
brake pads.

Brakes
A7. Why don't you have a standard price for the brake
discs, and therefore kits and conversions?
The prices that the manufacturer sets
for the brake discs depends on the offset measurement
of the disc. This is due to the fact that the disc centres
are all manufactured from solid aluminium billet and
therefore a bigger offset disc produces more wastage.
This is taken into account in the pricing. A 320mm disc
with an offset of 20mm costs £40 more than a flat disc.
We have chosen to standardised the prices to three levels,
rather than using a single price which would penalise
customers with flat discs.

Brakes
A8. Why do the caliper brackets supplied look quite
large?
The caliper mounting brackets are
designed for maximum rigidity with only a small penalty
of some added weight. The cross section between the
caliper and the fork leg is kept as large as possible
to maintain rigidity and resist flexing thus giving
maximum control and power.

Brakes
A9. Why don't you sell 4 piston Supermoto kits?
There are a number of reasons why
we sell a 6 piston kit rather than a 4 piston kit. The
4 piston caliper is actually larger than the 6 piston
caliper which means that there isn't much clearance
and it also weighs more. Some might say that the 6 piston
caliper is overkill, but with an adjustable ratio master
cylinder you can customise the braking power and feel
to suit your requirements or riding style. Also, having
the extra power will allow you to adjust the brakes
to suit slow and fast circuits. The 4 piston caliper
may be fine for a slow circuit, but the 6 piston caliper
has 30% more power and will be better suited for the
faster road racing and European style circuits.

Brakes
A10. Do the master cylinder and clutch levers fit fat
handlebars?
Yes they do. Fat handlebars taper
down to standard 22mm diameter at the ends of the handlebar
allowing standard sized components to be fitted.

Brakes
A11. My bike has 3 brake lines on the front brake system
but you only supply 2 in your kits and conversions.
Why?
At a very basic level, 2 brake lines
are cheaper than 3. From the functional and safety point
of view, all 3 line kits have a link which passes over
the front tyre, which is contrary to FIM and ACU stipulations.
In the event of an incident or tyre failure this may
become broken or damaged, rendering the front brake
useless when you need it most! Any bike will perform
just as well using 2 brake lines rather than 3.
Tyre Warmers
Tyre Warmers
A1. Can tyre warmers damage your tyres?
Cheap tyre warmers which do not use
good quality insulation allow the wire to get too close
to the surface of the tyre, overheating and scarring
those parts of the tyre. These parts of the tyre will
become hard and therefore the grip will be reduced.
The Chicken hawk tyre warmers place the heating element inside a thermo-conductive
fabric which in terms heats the tyre consistently throughout.
This reduces the risk of damage.

A1. How long will the batteries last in the MyChron
Basic/Plus?
Batteries typically last around 40
hours.

Data Logging
A2. Which temperature sensor
would you recommend I get included in the price?
Probably the most sensible measure
you should monitor is engine temperature to avoid the
engine overheating and causing damage. Therefore, if
you have an air cooled engine you should get the cylinder
head temperature sensor and if you have either an oil
or water cooled engine you should get the water/oil
temperature sensor.
Collecting exhaust gas temperature
data is more for people who need an understanding of
how exhaust gas termperature and fuel mixture are linked
and want to play around with the mix and anaylse the
impact.

A3. Why would I want to buy the MyChron Plus version
with the wiring loom?
The wiring loom allows you to power
the display unit directly from your bike battery, removing
the need to install batteries. Also, if you are using
the device as a replacement dash, when you turn on the
bike the display will be powered up automatically. It's
also more secure in this situation because when you
are away from the bike, people won't be able to turn
the display on and interfere with the configuration
you have set up.
Also, modern bikes have very advanced
ignition systems, where the RPM pick up supplied with
the battery powered Plus would not work. The wiring
loom allows connection directly to the bike's own ECU
or brain.
Another benefit is that if you have
the version with the wiring loom there is no additional
junction box to find room for on your bike.
Please note: it is not possible
to use the wiring loom with the battery powered.

A4. Can my friends and I use the same Infrared transmitter?
Yes. If you are all running variants
of the MyChron products, you can use the same transmitter.
Also, if you all have your own transmitters, you could
set them up at various points around the track to do
split lap timing.

Data Logging
A5. Can my friends and I download our data onto the
same computer?
Yes you can. The Race Studio
Analysis software recognises different devices and will
keep the files separate. You can also assign the data
to specific riders and at a later date copy the files
for that rider to another machine.
