I just searched the HD P&A site and they carry no extended brake pedals for my '15 RGS or any of the tourers from '14 up that I checked. The other, non-OEM sites specify with or without fairing lowers, so shop carefully. I appreciate your position - under the pedal and boxed in by the lowers. I use soft lowers during our short winter so it's not much of a problem and FWIW to others, the regular, no-lowers pedal works there. BTW, the Kuryakin model is only a hundred clams.
Frankly, I think that the extended/lowered reach ought to be the mfr's default with the current OEM length (IMO, too short for most) as an option for our brethren requiring/desiring less reach. My thinking is that if your feet can reach the ground while upright, you'll have more than enough reach to get to the brake pedal. So much in fact that you have to go toe-under to fully ground on the floorboard.
