I have a RSD Air Cleaner on my 2010 Fatboy Lo, no problems with the fitment or worrying about you leg getting caught on the aircleaner. Its a bit chunky yes, but it won't interfere with your leg. 

My Fatboy Lo has many RSD parts installed on it now, great quality also fuctional and the RSD parts look great.

RSD Aircleaner, RSD Fuel Cap & Dummy Cap, RSD Cam Cover, RSD Derby Cover, RSD Brass Hand Grips, RSD Brake Master Cylinder Cover, more to come.

I have black V&H big shot and the contrast cut RSD AC on my wide glide..... in my humble opinion that combination is sick! The RSD AC is top quality! My RSD tracker grips on their way as we speak ;-)

I agree with Ozroder, the AC is bulky (to me that's part of the appeal) and it does push your right leg out but I have no probs braking.
