Did any HD come out with this style riser but to suit a 1 inch bar?

 

It's a 1.5" riser, with a ported top clamp.
The finish would be the hardest thing to find about those.

 

The Origional ones I took off were similar, but all chrome and not open in the center. OEM for 2016 FXDB Streetbob bob. Bars ( chrome 1” mini apes 10”high ) and chrome riser with fairly new urethane bushings are in Dyna parts for sale section -VG cond. ( cheap) but your in Japan -shipping would be mega bucks. Anyway, just a thought…
