BREAK-IN INSTRUCTIONS
The component surfaces of a new motorcycle, despite undergoing precision processing, are not as smooth as the components of
motorcycles that have been running for a long time. This explains why running-in a new motorcycle is so important.
To achieve optimal settling of the moving parts, a new motorcycle must reach maximum performance gradually.
The main rules to comply with are:
1. After cold start, warm up the engine for about 1 minute before starting to use the motorcycle.
2. During the first 3 hours of use (1 hour for competitive use) the engine must be used only up to a maximum of 50% of its power.
Moreover, the number of revs must not exceed 9000 rpm for 250 cc engines and 6000 rpm for 450/530 cc engines.
3. During the following 5 hours of use (1 hour for competitive use) the engine can be used up to a maximum of 75% of its power. Ride
the motorcycle under different conditions (road, easy off-road stretches). Do not make long journeys without ever closing the throt-
tle. Progressively increase and reduce the opening of the throttle, alternating acceleration and deceleration with short periods of
constant speed.
Make sure that the coolant does not reach excessive temperatures (defined by fluid leaking from the bleeder hose).
By following these rules, you will obtain maximum performance and longer engine life.
Carry out the operations described in the “Maintenance Schedule” during the break-in period.
Pay special attention when replacing the oil and cartridge filter as the metal particles may detach from the surfaces in contact
with the engine during break-in, circulate in the oil and deposit in the filter. Therefore, replacing the oil and the filter allows these
particles to be removed from the engine definitively.
WARNING
THE 250Fi/450Fi/530F EN/MX/SMX MODELS HAVE BEEN DEVELOPED UNCOMPROMISINGLY FOR OFF-ROAD COMPETITIONS. ALTHOUGH THE EN
MODELS ARE APPROVED FOR ROAD USE, WE RECOMMEND CAUTION WHEN USING THEM ON THE ROAD. ESPECIALLY AVOID LONG STRETCHES
AT MAXIMUM SPEED.
