WHAT STANDS OUT? Here’s a list of things that stand
out with Moto-Master’s replacement KTM rotors.
(1) Company. Moto-Master is a Netherlands-based
brake company. It stocks a complete range of brake kits,
rotors and oversized brake applications. MXA has tested
Moto-Master’s oversized rotors on almost every brand of
Japanese motocross bike with great success, but with
KTM, Kawasaki and Honda going oversized for 2015
(although KTM has been oversized for years), we looked
to Moto-Master for our undersized and underpowered
Yamaha and Suzuki brakes.
( 2) Flame. The Moto-Master Flame rotor looks like the
buzz saw from the Perils of Pauline. The aggressive shape
isn’t just for looks, though. It helps dissipate heat to keep
the rotor from warping over the long haul.
( 3) Installation. The Moto-Master rotors installed
directly to the stock hubs with no hassle. The only special
measure we took was to use new brake-rotor bolts. When
mounting the rotor, use a medium-duty Loc-Tite on the
( 4) Rotor prep. We wash all-new brake rotors with
soap and water to get rid of any residual contaminants.
We prefer not to use contact cleaner, but it will do in a
( 5) Break-in. Since brake pads work by mating their
surface area to that of the rotor, it is best to install new
brake pads at the same time that you mount new pads.
We break in new pads and rotors by riding the bike in
second gear across a flat field and then slamming the
brakes on hard. We do this 10 times (with 30 seconds
between braking to allow the brakes to cool). Do not
break in the brakes and rotors by dragging them.
( 6) Performance. The hardened stainless steel
Flame rotors are laser-cut, CNC-drilled and surface-machined to provide almost perfect flatness. That is
the key to solid braking. Once our Flame rotors were
broken in (and the pads seated to them), the stopping
power was impressive. And because new rotors are still
at maximum thickness, they make the brake feel better
at the lever. This is a night-and-day mod for
2015 Yamahas and Suzukis.
WHAT’S THE SQUAWK? No complaints.
The buzz-saw look tells you that the
Moto-Master brakes mean business.
