WHAT IS IT? AP Racing’s
ORR sintered metallic brake
pads use material with a high friction coefficient
that
works over a broad temperature range. ORR is
an
acronym for Offroad Racing.
WHAT’S IT COST? $35.99
(a pair).

WHAT STANDS OUT? Here’s
a list of things that stand out with AP Racing’s
ORR brake pads. (1) Friction rating.
Brake pads are designated by an A through H
friction rating, with H being the highest coefficient
number. The ORR pads are designated HH. More
friction means more stopping power. (2)
Development. The AP brake pads are
designed and manufactured in London, England.
Engineers use an inertia dynamometer to examine
the friction produced by the brake pads at different
operating temperatures, pressures and rubbing
speeds. AP Racing developed the ORR pads several
years ago, but they have not been available
to the American public. Why?
The U.S. importer waited for approval from their
sponsored race teams to make sure the pads were
ready for prime time. (3) Caveat.
We tested the AP Racing brake pads on a 2010
Honda CRF450 against OEM Honda pads.
Everyone in the brake business will tell you
that Honda’s stock pads are very good.
Additionally, the MXA wrecking crew has tried
lots of different aftermarket brake pads, and
we generally prefer OEM pads. The AP ORR pads
had their work cut out for them. AP RACING ORR
BRAKE PADS (4) Front brake pads.
The front AP Racing ORR pads produced a crisper
feel on initial engagement than the stockers.
The feel remained good, with improved modulation,
as we squeezed harder on the brake lever. The
biggest difference between the AP and OEM pads
was that the AP pads had more grab at the first
touch of the lever.
They were also easier to break in. (5)
Rear brake pads. With the rear brake
pads, we wanted to see how well they resisted
overheating (which is very easy to do on a CRF450).
One of the downsides of overheating your rear
brake pads (apart from squealing and boiling
the brake fluid) is that the pads never work
as well again. Overall, the MXA wrecking crew
didn’t find that the feel or modulation
of AP’s rear brakes was any better than
the stock OEM pads, but even though they lost
some performance after overheating, we didn’t
feel the need to replace them. (6) Fluid.
We used AP Racing PRF 660 fluid with both the
stock and AP pads. It has a very high boiling
point (608 degrees Fahrenheit).
About: AP Racing
Anybody who races knows the key to going
fast is being able to brake. Brake pads are
one of the most important and also one of the
most commonly overlooked chassis components.
AP Racing in England has been manufacturing
high quality disc brake systems since 1966 providing
customers and race teams with "the world's
best stopping power." Since their inception,
AP Racing has won countless championships worldwide.
The technology and experience they gained from
their extensive NASCAR and Formula One car racing
has carried over into their Motorcycle and ATV
line of braking systems.
AP Racing's exclusive brake
pad material offers exceptional feel and long
wear life. We believe AP Racing brakes are not
for everyone, only those looking for the world's
best brake performance.
