Selling my 12" apes. Ran these for a year without issue and have little to no scuffing and no damage to the bars. 1" diameter for stock Harley controls or aftermarket. they're dimpled to allow for stock Harley controls too. Super comfortable bars. 9" wide mounting point, approx 8" pullback. Recently swapped to a different style of bars that don't require the risers, as to not have these clutter up space, wanting to sell them on.
