0.1.1. FOREWORD

- This manual is intended for use by aprilia Dealers and their qualified mechanics. Certain information has been
omitted intentionally, as this manual does not purport to provide a comprehensive treatise on mechanics. The
persons who will use this manual must be fully conversant with the basics of mechanics and with the basic
procedures of motorcycle repair. Repairing or inspecting a motorcycle when one does not possess such basic
knowledge or training could result in improper servicing and make the motorcycle unsafe to ride. For the same
reason, certain basic precautions have been omitted in the descriptions of repair and inspection procedures. Take
special care to avoid damage to motorcycle components or injury to persons. aprilia s.p.a.'s mission is to
constantly enhance the riding pleasure of final users through the on-going improvement of its products as well as of
the relevant technical literature. All aprilia Points of Sale and Subsidiaries worldwide are kept updated on major
engineering changes and modifications to repair procedures. Such changes and modifications are then reflected in
the next release of the relevant manual. When in doubt about an inspection or repair procedure, please contact the
aprilia CONSUMER SERVICE (A.C.S.) DEPARTMENT, who will be glad to provide full information on the
procedure in question as well as on any updates or engineering changes affecting the motorcycle under
consideration.
aprilia s.p.a. reserves the right to make changes to its products at any time, barring any such changes as may alter the
essential features of a product as specified in the relevant manual.
