I don't feel like instructing Greg about the importance of matching
the front spring rate(s) to the rear spring rates and why that's
important to the overall ride comforts as well as traction balance.
And, if he found a set of forks for a more modern motorcycle which
used a 17-inch front wheel, he would still have a handling problem
because the rear wheel is probably a 12 or 14-incher.
The rider of a two wheeled vehicle with such a wheel/tire diameter
mismatch feels like the bike doesn't "want" to turn into a corner and
then it feels like the rear end is falling out from under him is the
turn.

Who said he would?

Adapting "X" axle and wheel to "Y" forks is no problem.
I could equally design completely new forks and machine them,
but if existing forks could be shortened it would cut costs drastically.

You'd have to adapt a smaller diameter scooter wheel (maybe a 12~14
incher) to any motorcycle fork that you might find.
The typical small motorcycle front wheel just wouldn't fit under the
front "fender" of an NZeta...

The original wheel is sufficient - 12" and there's just room for
two yokes below the head. Machining up yokes is not a problem
and gives me the chance to increase the trail. (curreently 75mm/3")
Modifying other forks would make fitting a disk brake easy.
Didn't think of Wikipaedia, must have a look!
