Mike,
Not being familiar with that bike, and also probably not having the
same 'aesthetic' values, what I would consider 'workable' probably
isn't going to be the same as your 'workable'. So, take this for what
it's worth.

Does your bike have a fairing? What are the chances of mounting an
antenna on that, if it does have one? Is it fiberglass? How about
just running a strap to the frame? Considering the size of
'groundplane' required by a typical VHF/UHF antenna, a bike isn't all
that small. Getting that antenna 'connected' to the frame ought'a do
just fine.

The idea is certainly do-able, so I think the 'aesthetic' value is the
'catch'. That's up to you...
