I like it. The one time I had a full length front fender on my race bike, I broke it off in a minor lowside during a wet race. I was out for the day because I couldn't see at all without it... a huge rooster-tail of water right in my face.

I have used the Acerbis supermoto fender, and a shortened stock fender with success, but I've always kind of liked the low fenders I've seen on some European street supermotos.
