What they told me was that to wire it properly they had to run wires down the frame and back up again and the hole (i do not know which one now) will not accommodate all the wires. What i do know is that the dealer did a good job themselves in talking me out of it. They even started telling me how much better heated gloves are. They must know something because they simply did not what to do it at the end.
Hey Mano,
Heated grips came standard on my '08 Duracell and I looked at them to install on my wife's Ultra. After doing some research I decided to put Heat Demons on my wife's bike... Even the techs who installed them said that they are way better than the H-D heated grips and much more reasonably priced.
They also work with ANY grips, so you can keep the awesome looking grips that came with your bike.
