3 IMPORTANT NOTES 15
3.4 Service
A prerequisite for perfect operation and prevention of premature wear is that the service, care, and tuning work on the engine and chassis
is properly carried out as described in the Owner's Manual. Incorrect adjustment and tuning of the engine and chassis can lead to damage
and breakage of components.
Use of the vehicle under difficult conditions, such in rain, high heat or with a heavy load, can lead to considerably more rapid wear of
components such as the drive train, brake system, or suspension components. For this reason, it may be necessary to inspect or replace
parts before the next scheduled service.
It is imperative that you adhere to the stipulated run-in times and service intervals. If you observe these exactly, you will ensure a much
longer service life for your motorcycle.
3.5 Figures
The figures contained in the manual may depict special equipment.
In the interest of clarity, some components may be shown disassembled or may not be shown at all. It is not always necessary to disassem-
ble the component to perform the activity in question. Please follow the instructions in the text.
