Aprilia SR50R - Service manual > Running-in

RUNNING-IN

Proper engine running in is essential to preserving engine life and performance over time.

Twisty roads and gradients are ideal to break in engine, suspension and brakes effectively.

Varying speed frequently is also recommended.

This will vary the amount of stress placed on vehicle components continuously, allowing engine parts to cool down when less stressed.

While it is important to put a certain amount of stress to engine components during the running-in period, it is equally important to spare the engine at this stage in the vehicles life.

WARNING Top acceleration performance is only obtained after covering the first 500 km (312 mi).

Observe the following instructions:

• Avoid harsh accelerations and do not flip the throttle open abruptly when the engine is running at low speed, both during and after the running-in period.
• 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 stroke for long periods of time.
• From 300 to 500 km (187 - 312 mi), do not keep the throttle twistgrip open for more than three fourths of its stroke for long periods of time.

WARNING After covering the first 1000 km (625 mi), perform the checks listed in the "After running-in" column, see REGULAR SERVICE INTERVALS CHART to avoid personal injury to yourself or third persons, or vehicle damage
