ok i'll add some thoughts & opinion here in the limited time a have atm.
The Zeds weight is biased to the front given it's chassis design and engine placement, hence whilst replacing the monoshock may improve the rear squat & traction it will promote further force distribution to the forks (the weak point of Z750/1000 having the 'deadfork' design). Suspension requires balance to operate effectively otherwise you will experience certain 'wallowing' under cornering forces, diving under brakes and squatting under accelleration.
Whilst valving and spring changes can be a positive way of improving OEM suspension... on certain models it's only marginal and further changes are required.
I've spent much time with James of
Zenodamper in researching & developing (see trial & error & success) in finding the most performance & cost effective way of improving on what is a great bike lacking.
The 09Z750 was fitted with a Penske shock valved & sprung to suit which improved the rear... then it was onto the forks which saw ZX636 internals modified, valved and sprung to bring both legs alive.. It's never as easy as a bolt-on drop-in solution...
Front-end swaps? once again it's not an overnight fix and can easily exceed the cost of working with your original parts, not to mention throwing out the designed geometry.
With & without sounding like a good 'plugging' of his services, as many have already suggested.. contact James as he now has a winning formula for these models. i would stake whatever reputation i have on it.
