Yamaha YZF-R125 Owners Manual: Periodic maintenance and adjustment
Periodic inspection, adjustment, and lubrication will keep your vehicle in the safest and most efficient condition possible. Safety is an obligation of the vehicle owner/operator. The most important points of vehicle inspection, adjustment, and lubrication are explained on the following pages.
The intervals given in the periodic maintenance and lubrication chart should be simply considered as a general guide under normal riding conditions. However, depending on the weather, terrain, geographical location, and individual use, the maintenance intervals may need to be shortened.
WARNING
Failure to properly maintain the vehicle
or performing maintenance activities
incorrectly may increase
your risk of injury or death during
service or while using the vehicle. If
you are not familiar with vehicle service,
have a Yamaha dealer perform
service.
WARNING
Turn off the engine when performing
maintenance unless otherwise
specified.
