Aye Andy,
As a track bike for racing it probably goes very well, providing the components have had the tuning work done on them. So, why the bother with the "road legal" clutter that gets in the way and adds weight?

As a road bike all the fitments and tuning that make it a track bike are a pain in the neck, back, arms, legs! But, the slim lines, lightweight and torquey motor are all good points. This adds up to a bike with the same problems as those with ape hangers, peanut tank, hard tail and raked forks!

So, I tend agree with your final statement "Give me a C90 and the time and money wasted on this "art" to go ride instead please."

However, I'd rather use a 350cc - 650cc torquey single, with a comfy seat, supple controlled suspension and good ergonomics and spend the time on the minor roads.

Happy dawdling, bimbling, tootling, with the occasional rapid run for many years to come! Good health.
My regards, Bill
