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

VERY 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.

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
