Break-in of New Motorcycle
The first 600 miles (1000km) are the most important in the life of your
motorcycle. Correct running-in operation during this period will help
ensure maximum life and performance from your new motorcycle. The
parts are manufactured from high quality materials, and machined parts are
finished to close tolerances. Correct running-in operation allows the
machined surfaces to lap each other and bedding together smoothly.
Freeing up of the internal parts is achieved after approximately 60 running
hours, and during this running-in period the engine will loosen up and
performance will improve.
Maximum Throttle Operation Recommendation
This table shows the maximum recommended throttle operation
during the break-in period.
Initial 100 miles (160 km) Less than 1/2 throttle
Initial 250 miles (400 km) Less than 3/4 throttle
Vary the engine Speed
The engine speed should be varied and not held 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 component during
break-in ensure this mating process. Do not, though, apply extensive load
on the engine.
Avoiding Constant Low Speed
It is not benefit to break-in the engine to operate it at a constant low
speed. Allow the engine to accelerate freely within the recommended
maximum limits. Do not, however, use full throttle for the first 1600km.
Allow the Engine Oil to Circulate before Riding
Allow sufficient idling time after warm or cold engine start up before
applying load or revving up the engine. This allows time for the lubricating
oil to reach all critical engine components.
