Those are the actual numbers I measured on my bike in the garage. The 2" offset I'll have to re-check. I am a bit suspicious of that number myself.
EDIT: Assuming offset I'm getting right, being center of steering stem plane to center of axle plane as they run diagonally through the top of the stem and fork, then I re-measured a 2 inch offset.
Rear axle to swingarm I took just the other day, just measured center of pivot to center of axle, used a level running through midpoint of the swing arm pivot and a 90 angle to measure the distance between that plane and the vertical line through the rear axle. Some trig later, 13.2 degrees is the swing angle, a little steep, but, generally fantastic for a sporting feeling and is actually consistent with the behavior I've noticed. Shallow angles push wide on power a lot, steeper grip and go without excessive widening of the steering radius, or slip spin and drift smoothly. Mufasa does the later, either drives beautifully out of turns or slips and spins predictably.
As soon as the forks go back on later this week (I hope), I'll carefully double check all the dimensions again, to make sure.
Remember, as the shocks get longer, wheel base gets shorter and swingarm angle gets steeper. It's a combined effect I think of both more preload and more length on the back that causes such a drastic change in measured geometry.
When I say my bike is "flickable" it's an understatement, its downright ****ing agile. If you follow me around while were puttering about slowly, you'll see me oversteer turns a lot and have to correct wider, the bike just falls into turns, just like my Daytona does. In that thread I warned against people following my route of changes, 1" taller + high spring rates + the tire size changes really puts the bike into what some would call "scary" territory.
In fact, when we were out with Mike you may have noticed it, I distinctly remember having to correct wider a number of times.
At some point I'll have to toss you the keys so you can go evaluate for yourself
