I got the dual sport helmet because I wanted the visor for driving into the sun in the evenings. The helmet fits like a body part; very snug, we'll vented high quality pats & pieces. While my ST is by no means a dual sport bike, this full-face helmet says the visor is fine upto legal highway speeds. With the ST-1300 adjustable windshield I can adjust my ride and am completely protected from sun and wind. So far a great helmet, now to install my Cardo G9. More as I learn . . .
