- Measure with a metric tape from pivot center to center and input into Vehicle Preferences. All distances are in millimeters (mm).
L1 = Swingarm pivot to upper transducer pivot
L2 = Upper transducer pivot to lower transducer pivot
L3 = Exposed maximum transducer travel
L4 = Swingarm pivot to lower transducer pivot
L5 = Swingarm pivot to rear axle
L6 = Perpendicular distance from swingarm centerline to lower transducer pivot (not necessarily the bracket length)
L7 = Swingarm pivot to the ground (bike level) (accuracy not too critical)
L8 = Rear axle to the ground (bike level) (accuracy not too critical)

Input a Laid-Down Transducer Travel and it will display the corresponding Vertical Wheel Travel. Note that when you input Transducer Travel that is too high the Wheel Travel displays "N/A". What this means is that at some Transducer Travel the geometry is impossible mathematically. This can also show you how much Transducer Travel you need for the Maximum Available Wheel Travel.
It is possible to mount the Transducer in an impossible configuration. There must be enough Transducer Travel available as well. To check this, input the Transducer Mounting Measurements in Vehicle Preferences along with Maximum Wheel Travel. When you click the OK button it will check the configuration and give an error message if there is a mathematical problem.
It is also possible to mount the Transducer Head too low so it hits the swingarm before bottoming. Use a tape measure at the rear axle to indicate the available rear wheel travel. Lay a rod on top of the swingarm at the pivot up to the bottomed-out position of the swingarm. Make sure there is clearance.
Axle position affects the maximum available wheel travel. If the axle is mounted forward the travel will be slightly less and if it is mounted to the back the travel will be slightly more. If you want to know exactly you must disassemble the shock, remove the Bottom-out Bumper, reassemble and mount the shock then measure the travel.
