This relatively simple device really does work. And it can be adapted to the factory Ducati Ride Height Measuring tool as well. Below is the assembly shown off the bike. It consists of the ride height tool, a plastic ruler and a portion of the ruler case. I picked these up for under a buck at a stationary store. You may remember these if you are old enough. But in any case, the ruler slides into the grooves of the box and it acts as a pencil case. |
 This is a closer view of the device in action. From here you can see the dimension from the top edge of the tool to the center of the axle. In this case it is: 222mm. The picture below shows where the ruler rests upon the 54mm dia of the Pit-Bull stand. |
 This is what it looked like before I butchered it.
|
 As I mention above. The ruler is resting on the 54mm dia tube of the Pit-Bull stand. Now, in order for the ruler to represent the true center of the axle you must remove exactly half the dia of the tube. The result is a curved shape removed up to the 27mm mark. Ideally, the curve should have a radius of 27mm.

So, what mods do you have to make besides trimming the ruler length? Below
shows the biggest mod. Cut two slots into the sides of the case allowing
the tool to slide through. Make it a transition fit.
|
When you make those two slots. You should try
to make them such that you maintain a 90 degree perpendicularity with the
tool's top surface. This will ensure correct alignment with the axle as it
travels it's stroke.
|
|
On a side note: this is the cross sectional view of the case after you cut
it to length. The final length does not really matter so as long as it
provides enough tension to keep the ruler in place and not slide out of
the case.
|
The real beauty of this is the ability to set your ride height, static sag, and dynamic sag by yourself quickly and easily and see the effect of changes real time. |
