A Few Words About Safety
Your safety, and the safety of others, is very important. And operating this motorcycle safely is an important responsibility.
To help you make informed decisions about safety, this manual contains a section devoted to Motorcycle Safety, as well as a number of Safety Messages
throughout the manual.
Safety Messages are preceded by a safety alert symbol and one of three signal words: DANGER, WARNING, or CAUTION.
These signal words mean:
DANGER You WILL be KILLED or SERIOUSLY HURT if you don’t follow instructions.
WARNING You CAN be KILLED or SERIOUSLY HURT if you don’t follow instructions.
CAUTION You CAN be HURT if you don’t follow instructions.
Of course, it is not practical or possible to warn you about all hazards associated with operating or maintaining a motorcycle. You must use your own good
judgement.
