General Information
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 1,500 km):
• Engine speed can gradually be increased
to the rev limit for short periods.
Both during and after running-in has been
completed:
• Do not over-rev 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.
