Running-In

Running-in is the name given to the
process that occurs during the first
hours of a new vehicle's operation.
In particular, internal friction in the
engine will be higher when components
are new. Later on, when continued
operation of the engine has ensured
that the components have 'bedded in',
this internal friction will be greatly
reduced.
A period of careful running-in will
ensure lower exhaust emissions, and
will optimise performance, fuel economy
and longevity of the engine and other
motorcycle components.
During the first 500 miles (800 km):
▼ Do not use full throttle;
▼ Avoid high engine speeds at all times;
▼ Avoid riding at one constant engine
speed, whether fast or slow, for a
long period of time;
▼ Avoid aggressive starts, stops and
rapid accelerations, except in an
emergency;
▼ Do not ride at speeds greater than
3/4 of maximum speed.
From 500 to 1,000 miles (800 to 1,600
km):
▼ Engine speed
increased to the rev limit for short
periods.

can gradually be
Both during and after running-in has
been completed:
▼ Do not overrev the engine when cold;
▼ Do not let the engine labour. Always
downshift before the engine begins
to 'struggle';
▼ Do not ride with engine speeds
unnecessarily high. Changing up a
gear helps reduce fuel consumption,
reduces noise and helps to protect
the environment.
