I like riding in the rain yet a find very few that do.
-take a old gogle lens and tape it to extend your visor
-tape off your helmet and visor vents
-get those covers that go over your barkbusters to keep gloves fairly dry
-plan on getting wet and learn to love it, wet dirt is awesome...
-also smooth power delivery is criticall, steer with your rear brake and be carefull not to tweek a knee cause you slide out when not expecting
