Yamaha YZF-R125 Owners Manual: Operation and important riding points
Read the Owner's Manual carefully to become familiar with all controls. If there is a control or function you do not understand, ask your Yamaha dealer.
WARNING
Failure to familiarize yourself with
the controls can lead to loss of control,
which could cause an accident
or injury.
TIP

sensor to stop the engine in case of
a turnover. To start the engine after a

crank when pushing the start switch.
