Most bike-hauling hardware I've experienced is, more-or-less, "UNIVERSAL," in sizing. That is, fits a great variety of different-size bikes. Examples: Harbor Freight front-wheel chock, trailer-hitch bike carrier, single-rail bike trailer, etc.
If precision to the degree you suggest is necessary for your packaging, the diameter/circumference of the front tire can be found on the Internet (I researched this dimension myself, re-calibrating the speedometer on my KTM 690 with "trick" rims and tires. The process is digital; however . . . one must SNIP an OEM wire to perform it. Reckon some EU regulation fights fraudulent speedometer representations with the factory connection.).
Now, distance from front tire to rear axle? A visit to a dealership, or to the immediate seller, with a tape measure should answer this question to a practicable accuracy, IMHO.
And, truth be told, I've loaded bikes in a pickup bed, leaned against tire casings propped against the bed sides. This expedient may or may not be adequate hauling your bike from your point of purchase to your home; oughta work with a utility trailer as well.
With your unlimited budget, I'm certain you'll find the KLR650 meeting the exact criteria you have shared on this website.
