I seem to recall someone (or more than one ...) here is/was involved in

Looks like the best-handling option is going to be unequal length A-frames
with CV jointed half shafts and dual inboard disc brakes . I'm undecided
about springing options , whether coil-over shocks , maybe a single
transverse leaf . Either option will require a torsion bar to control body
roll . Going to have to have an enclosed spider differential setup , with a
sprocket mounted for chain drive - maybe from an ATV ? Front suspension hubs
from a FWD car look like the cheapest option ...
And it all needs to fit into a 14 x 14 x 27 inch package , plus the width
of the A-frames , and the mounting points extending to the front to bolt it
to the M/C frame . I'm considering using 1" sq tube and 1x2" tube for the
frame members . I'd like to use the original swingarm and shock absorber
mount points , since they're designed to support the loads ... and I
haven'rt even begun to consider body work to cover it all .

Do you need to implement control loops in software?
"Applied Control Theory for Embedded Systems" was written for you.
