By “Front Wheel Trail” I’m meaning the horizontal distance on the ground between the centre of the tyre contact patch and the intersection with a projected line of the steering head axis.
It would be interesting to compare that change with the magnitude of increase/decrease in front wheel trail when you raise or lower the forks in the yokes or adjust the height of the rose joints in the rear suspension wishbone/tierod? Of course dropping the front, or jacking up the back end affects caster angle, wheelbase and other aspects too.
That could be how the racers try to get the Monster back to 888 and SS geometry.

You fairly well echo my thoughts as I walked away from SS after the little try on.
The SS fork legs protrude from the top yoke by about 50/60mm and the clip ons, fit above the yoke.
I had thought that when I do the swap to monster yokes that bringing the bike up on the legs (less leg above the yoke) would slow the steering right down, by increasing the trail/castor, but now I have discovered the offset difference I am hoping that it will come back to close to either the original SS geometry or the Monster's.
Since I don't know any of the specifics of the geometry of either bikes without measuring carefully, this is all hopeful speculation.
I doubt they differ very much, but get there in different ways.
Since I will be hacking the rear right off the SS and adding different suspension, I do have the option of tuning it via rear ride height. It will need some careful sums, a little educated guesswork and then the building in of some adjustability in the ride height. Adjustable shocks being the easiest solution I think.
I daresay it will take a few test rides to get it right, but I shouldn't be too far out if I stay somewhere near the SS and Monster geometry.
