This is the HRF seat bolt style whip mount that hangs over the rear fender and bolts up to the seat bolt holes. There is no drilling on the bike needed to use this whip mount. It comes with longer seat bolts and some felt pads to add to the mount where it might rub on the rear fender. Super easy installation.
**** HRF RECOMMENDS USING A 1/4" OR 5/16" THICK SAFETY FLAG. DO NOT USE THE BIG 3/8" THICK BUGGY/TRUCK FLAGS. THESE ARE TOO BIG FOR BIKES ****
