The HD parts listing for the stock drive belt on the Breakout describes it as 132 Teeth and "24mm wide".

But when I look online for a 131 tooth version, I see no "24mm" width, but plenty of "1 inch" width.

Is the 24mm width unique to Harley dealers, or is a "1 inch" wide belt (which is 25.4mm) equivalent to a 24mm wide belt?

Before anyone asks "why" a 131T, when you change the 32T tranny output pulley to 30T, you need a shorter belt because apparently the adjustment range on the belt tension won't handle the slack introduced by the 2 tooth change on the tranny pulley.
