I'm only About 5'9" and i surely don't need them back any. I guess it's not so much *need* for some people but simply thier preference. but i sure can't see how it could be a problem for anyone our size. i mean, i can see wanting mid pegs instead of forward, but thats just preference. i could actually ride fine if they were even further forward. might even be nice ! The only thing i don't like is that with the forward pegs your leg muscles are always slightly working to keep your feet balanced. So i ordered those Kuryaken switchblades with the heel spurs for a resting point at 2 positions of the foot to simulate a floorboard and relax the leg muscles. That may just help him feel comfortable in the stock position too.
