Not sure about the rest of the Dyna's but im riding a 2007 Superglide Custom which is very comfortable.
Had the forward controls fitted whch i found uncomfortable after about 70 miles,so fitted the middle foot pegs back on, so now i have the forward and middle foot pegs on,but for some reason the forward footpegs dont seem to be giving me probs anymore, so havnt had to use the middle footpegs,Guess i just got used to the forwards.
I also have a Sundowner seat which i use when im touring around Europe,it not the greatest looking seat around but its comfy and wouldnt be without it.
Guess i just got used to the forwards.
