3. CHECKING THE VISOR AND SUN VISOR
Before every journey, check that the mechanisms of the visor and sun visor are
working properly and that the visor and sun visor will provide sufficiently clear
visibility. Any dirt should be removed before riding.
Check the visor and sun visor for physical damage and cracks. A badly scratched
visor will considerably impair your vision and should be replaced before setting off
on a journey.
Caution:
Never use tinted visor or sun visor in conditions of poor visibility, when
riding at night or in a tunnel.
Caution:
Stop riding if visibility is poor.
