This one-piece 1 1/8” bar mount is precision machined from aircraft quality aluminum, with 3mm of adjustability forward or back (85mm span). They come with two machined spacers making them the same height as the stock YZ85 bar mount (Note: OEM YZ65 spacers are 10mm lower). Spacers can be removed and shorter spacers or no spacers can be used to lower the bars by replacing the 2 3/4" 7/16-20 bolts with shorter ones. Use 2 1/4" for YZ65 stock spacers. Comes with all necessary mounting hardware and two rubber cushions to insolate the handlebars from vibration. For fitment on OEM triple clamps with 85mm span.
