s for reducing fuel nsumptionur motorcycle’s fuel consumptionends to a large extent on your

ng style. The following tips can helpuce fuel consumption:

Warm up the engine before riding.Turn off the starter (choke) assoon as possible.Shift up swiftly and avoid high en-gine speeds during acceleration.Do not double-clutch or rev the en-gine while shifting down and avoidhigh engine speeds with no loadon the engine.Turn off the engine instead of let-ting it idle for an extended lengthof time, i.e. in traffic jams, at trafficlights or railroad crossings.

EAU00436

Engine break-inThere is never a more important periodin the life of your motorcycle than theperiod between zero and 1,000 km. Forthis reason we ask that you carefullyread the following material. Becausethe engine is brand new, you must notput an excessive load on it for the first1,000 km. The various parts in the en-gine wear and polish themselves to thecorrect operating clearances. Duringthis period, prolonged full throttle oper-ation, or any condition which might re-sult in excessive heating of the engine,must be avoided.

This motorcycle is fitted with superhigh-speed running tires. The fol-lowing points must be observed inorder for you to make fully effectiveuse of these tires.

● Never fail to use the specifiedtires in tire replacement. Othertires may have a danger ofbursting at super high-speeds.

● New tires have a relatively lowgrip on the road surface untilthey have been slightly worn.Therefore, approximately 100 kmshould be traveled at normalspeed before any high-speedriding is done.

● Before any high-speed runs, thetires should be warmed-up suf-ficiently.

● Always inflate to the correct tirepressure according to the oper-ating conditions.
