Aprilia SR50R - Service manual > Introduction

FOREWORD

• This manual provides the information required for normal servicing.
• 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; you are therefore invited to 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 ongoing improvement of its products as well as of the relevant technical literature. All aprilia Dealers 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. In case of need or doubt regarding repair and inspection procedures, contact the aprilia SERVICE DEPARTMENT, which will be pleased to help, as well as providing you with updates and technical modifications regarding the vehicle.
