If you want ultimate handling,buy a zx636 or whatever.
Unless you can ride the absolute wheels off the thing,regularly deck out the undercarriage and wear out your tyre edges faster than the centre,learn to handle what you've got and THEN try and improve it.
All this mechanical masturbation gets right on my nerves sometimes.

Hit the road.
Screw the rest.
If you're riding a Guzzi,you'll have fun.
