what are line levelers

[UltraNutZ]

they condition the DSP audio signals coming out of the stock radio on these 14 and up bikes.  They are required otherwise you'll be left to deal with the dealer with different flashes in the hopes they get it right which most are incapable of because of issues from moco with the flashes.
