Just my two cents worth and my own opinion....I am glad I didn't go for a full shield.. MY reasons are: I like the isea of having the helmet with the two shields...One, the sun or coated partial and the full clear pull down. On hot days, its nice to have some of the air cooling me off, down, it keeps the bugs from smacking me in the face, when raining, with rain-X on the shield..the air blows the shield rain off nicely, my visibility is much beeter all around with the existing shield being if I don't take care of a full windshield from scratches etc..well. At night, I feel the full windshield would have much more glare and rellection to deal with. Finally, of course, I really like the appearance of the existing shield and so do many who see the bike.
I have many compliments on the looks of this 500 and added to it all if of course again, the shield. All MY views and I wouldn't argue anyone elses!
