NOTE:
Dedicated to nothing but offroad racing, 250/450/525
SX/MXC/EXC Racing models make no compromises in their
design. As such, they do not include any radiator fan, and the
size of the radiator is dimensioned for optimum ergonomics.
In normal racing, the cooling system is sufficient.
If you use your motorbike in other conditions, please note that:
–
THE E-STARTER ALLOWS YOU TO START MXC/EXC RACING MODELS
AGAIN AT ANY TIME
. THEREFORE, TURN OFF THE ENGINE IF YOU
INTEND TO RUN YOUR MOTORCYCLE IN IDLE OR AT A STANDSTILL FOR
LONGER PERIODS OF TIME
(MORE THAN 2 MINUTES).
–A
VOID LETTING THE CLUTCH SLIP FREQUENTLY AND FOR EXTENDED
PERIODS
. THIS WOULD CAUSE THE ENGINE OIL TO HEAT UP, THEREBY
HEATING UP THE COOLING SYSTEM
. YOU SHOULD DRIVE AT LOW
SPEEDS
(4-STROKE STYLE - LETTING THE ENGINE PULL YOU) AND NOT
AT HIGH SPEEDS NOT BY LETTING THE CLUTCH SLIP
(2-STROKE STYLE).

–H
IGH RPM RATES WHEN THE ENGINE IS COLD HAVE AN ADVERSE
EFFECT ON THE LIFE OF YOUR ENGINE
. WERECOMMEND YOU RUN
THE ENGINE IN A MODERATE RPM RANGE FOR A FEW MILES GIVING IT
A CHANCE TO WARM UP
. AFTER THAT NO FURTHER PRECAUTIONS IN
THIS RESPECT NEED TO BE TAKEN
. THE ENGINE HAS REACHED ITS OPE-
RATING TEMPERATURE AS SOON AS THE RADIATORS BECOME WARM.
–N
EVER HAVE THE THROTTLE WIDE OPEN WHEN CHANGING DOWN TO
A LOWER GEAR

Braking
Close throttle and apply the hand and foot brakes at the same
time. When driving on sandy, wet or slippery ground use
mainly the rear wheel brake. Always brake with feeling,
blocking wheels can cause you to skid or fall. Also change
down to lower gears depending on your speed.
When driving down hill, use the braking effect of the engine.
Change down one or two gears but do not overspeed the
engine. In this way, you will not need to brake so much and
the brakes will not overheat.

–IN CASE OF RAIN, AFTER WASHING THE MOTORCYCLE, AFTER RIDES
THROUGH WATER AND IN CASE OF RIDES ON WET OFF
-ROAD TRACKS,
HUMID OR DIRTY BRAKE DISCS CAN DELAY THE BRAKING EFFECT. THE
BRAKES MUST BE PULLED UNTIL THEY ARE DRY OR CLEAN
.
–R
IDES ON SALT-STREWED OR DIRTY ROADS CAN ALSO DELAY THE
BRAKING EFFECT
. THE BRAKES MUST BE PULLED UNTIL THEY ARE CLEAN.
–DIRTY BRAKE DISCS CAUSE INCREASED TEAR OF BRAKE PADS AND
BRAKE DISCS
.
–W
HEN YOU BRAKE, THE BRAKE DISCS, BRAKE PADS, BRAKE CALIPER
AND BRAKE FLUID HEAT UP
. THE HOTTER THESE PARTS GET, THE WEA-
KER THE BREAKING EFFECT. IN EXTREME CASES, THE ENTIRE BRAKING
SYSTEM CAN FAIL
.
–IFTHE RESISTANCE IN THE HAND BRAKE LEVER OR FOOT BRAKE PEDAL
FEELS
“SPONGY” (TOO MUCH PLAY), THIS IS AN INDICATION THAT
SOMETHING IS WRONG WITH THE BRAKE SYSTEM
. DON’T RIDE YOUR
MOTORCYCLE ANYMORE WITHOUT FIRST HAVING THE BRAKE SYSTEM
LOOKED OVER BY A
KTM DEALER.
