No, not exactly. When we're talking about perch height, we mean the KTM handlebar perches on your bike. They come in a few different heights, and the most common are 28, 32, 37 and 42mm tall. That's measured from the handlebar perch mounting surface to the centerline of the handlebars. When you're configuring a stabilizer mount, 'height desired' is referring to the total combined height of the stabilizer mount, the topcaps, and spacers (if any). You can think about this as additional height (not including the handlebar perches), and ranges from 23-53mm, in 5mm increments. And when you select the 'height desired', we'll select the components to give you exactly what you want. Realize that this is not the simplest ordering process, but the technical nature of these products and the range of fit that we want to offer kind of dictates that things be this way. Hope it makes sense, and please let us know if you have any other questions.
