RUNNING-IN

1.4.1. RUNNING-IN
Correct engine running-is essential to ensuring proper performance and durability.
Twisty, hilly roads are ideal for an effective running-in of engine, suspension and brakes.
Vary speed frequently during the running-in period.
This will allow engine parts to be alternately loaded and unloaded, allowing them to cool down when unloaded.
While it is important to put some stress on engine components during running-in, it is equally important to avoid extreme
load conditions.
WARNING
Only after the first 500 km (312 mi) of running-in is it possible to obtain the best acceleration
performance from the vehicle.
Follow these recommendations:
•
Never accelerate completely and harshly when the engine is running at low rpm, either during or after running-in.
•
Until you have covered the first 100 km (62 mi), use the brakes gently and avoid harsh, prolonged braking. This will
help the brake pads bed in properly against the brake disc.
• During the first 300 km (187 mi) do not keep the throttle twistgrip open for more than half of its travel for too long.
• From 300 to 500 km (187 - 312 mi), do not keep the throttle twistgrip open for more than three fourths of its travel for
too long.
WARNING
After the first 1000 km (625 mi), carry out the checking operations indicated in the column "After
running-in", see REGULAR SERVICE INTERVALS CHART, in order to avoid hurting yourself or other
people and/or damaging the vehicle.
