HD does make an extended foward control kit for some models. It comes with brackets that move the shifter/peg foward and brake pedal/peg acouple inches farther foward. It also comes with an extra long shifter rod and an extended brake hose for the master cylinder.Check with your dealer to see if one is available for your particular bike.
Also, there are a bazillion different aftermarket foward controls. If you chose to go that route, I'm sure someone makes one that will give you a little more stretch a maybe a little more style too.
Not to mention a different seat could put you in a more comfortable riding position. Pherhaps lower and a little farther back.
If I can find the part # for the HD kit I'll post it .
