SCOOTER SAFETY
IMPORTANT SAFETY INFORMATION
Your scooter can provide you many years of service and pleasure if you take responsibility for your own safety and understand the challenges that you can meet on the road. There is
much that you can do to protect yourself when you ride. Y ou

accidents.
Keep your scooter in safe condition
For safe riding, it's important to inspect your scooter before
