Some manufacturers consider the outside bar measurement as “thick” while some refer to it as “fat.” Regardless, this is a measurement of handlebar thickness. Most companies sell handlebars in a 1.25 or 1.5-inch thick measurement. The clamp and hand control area narrows to one inch. This allows you to install bars with riser and stock controls.
This is the overall measurement from one bar-end to another.
This measurement is the distance of the flat section in the handlebar before the bars bend, rise, or pullback.
Knurled is the manufacturing process that adds texture to the handlebars. This offers a better bite to risers or mounts. Typically, two 1-inch grooves are machined into the clamping area.
The Knurl width is the distance to knurl marks or where risers clamp the bar. These marks have a measurement between knurl marks.
The rise height is the distance starting from the midpoint of the handlebar’s flat. This measurement goes to the center point at the highest end of the handlebar.
The pullback is the distance the bar pulls back away from the centerline through the bar middle.
This is the angle where the end bar sits around the center of the handlebar. Sweep refers to the hand placement angle.
The end rise is the measurement from the middle of the handlebar center to the middle of the bar.
This term refers to the drilling of small holes into the underside of the bar end where your hand controls sit, in the middle of the clamping area.
Swedged refers to the underside of the bar ends that get pressed into the handlebar. This creates a small indentation that lets you run the switch wires externally without cable pinching. Some companies drill and dimple handlebars.
