BREAK-IN FOR A NEW MOTORCYCLE
The forward explains how important the proper
running-in is to achieve maximum life and
performance of your new motorcycle. The following
guidelines explain proper running-in procedures.
The following table shows the maximum
recommended throttle opening during the break-in
period:
Initial 800 km
less than 1/2
To 1600km
less than2/3
VARY THE ENGINE SPEED
The engine speed should be varied and not hold
at a constant speed. This allows the parts to be
“loaded” with pressure, and then unloaded,
allowing the parts to cool. This aids the mating
process of the parts.
It is essential that some stress be placed on the
engine components during bread-in to ensure this
mating process. Do not, though, apply excessive load
on the engine.
AVOID CONSTANT LOW SPEED
Operating the engine at constant low speed (light
load) for a long time can cause parts to graze and
not fit close to each other. Allow the engine to
accelerate freely through the gears, without
exceeding the recommended maximum limits. Do
not, however, use full throttle for the first 1600 km.
ALLOW THE ENGINE OIL TO CIRCULATE
BEFORE RIDING
Allow sufficient idling time after warm or cold
engine start up before applying load or reviving the
engine. This allows time for the lubricating oil to
reach all critical engine components.

17
PERFORM THE NECESSARY PERIODIC
MAINTENANCE
The initial 1000 km service is the most important
to your motorcycle. During break-in all of the
engine components will fit close to each other
sufficiently. All adjustments will be restored, all
fasteners will be tightened, and the dirty oil will be
replaced.
Timely service during the 1000km service will
ensure optimum service life and the best
performance of the engine.
WARNING
Maintenance for 1000km should be
according to the “maintenance planning” in
the specification. Pay more attention to the
“NOTE”& “WARNING”.
