As I get more used to my bike, I'm finding the foot pegs are too far forward for my liking, even when I have them adjusted as far back as possible, I find my legs are seizing up with the footrest position as it is. After a 100 miles or so in the saddle I'm getting cramp in the top of my legs. Bear in mind I'm only 5'7". I would think it would be worse for a taller rider. Has anybody got aftermarket rear sets fitted and if so what are your conclusions.
