Safety Guidelines
Follow these guidelines to enhance your safety:
● Perform all routine and regular inspections
specified in this manual.
● Stop the engine and keep sparks and flames
away before filling the fuel tank.
● Do not run the engine in enclosed or partly
enclosed areas. Carbon monoxide in
exhaust gases is toxic and can kill you.
Always Wear a Helmet
It's a proven fact: helmets and protective
apparel significantly reduce the number and
severity of head and other injuries. So always
wear an approved helmet and protective
apparel. 2 P. 9
Before Riding
Make sure that you are physically fit, mentally
focused, and free of alcohol and drugs. Check
that you are wearing an approved helmet and
protective apparel.
Take Time to Learn & Practice
Even if you have ridden other vehicles, practice
riding in a safe area to become familiar with
how this vehicle works and handles, and to
become accustomed to the vehicle's size and
weight.
We recommend that all riders take a certified
course approved by the Motorcycle Safety
Foundation (MSF) or a state approved training
course. New riders should start with the basic
course, and even experienced riders will find the
advanced course beneficial.
For information about the MSF training course
nearest you, call the national toll-free number:
(800) 446-9227.

Other riding tips can be found in the You
and Your Motorcycle Riding Tips booklet that
