There was a guy on ebay who was doing a 'sports' mudguard. Thought of getting one myself. I've had a good look and a google and can't seem to find it though. I'll have another go.
Try searching for yamaha fzs600 fazer sports fender, or sports mudguard.
The picture of it fitted on the bike was of a blue Foxeye with bellypan, hugger and sports mudguard, and the carb covers and side pannels were also colour matched blue. The photo was a 3/4 front shot from the off side.... if it helps
