AMEN!
The improved springs WILL give more suspension travel - so then decent damping can actually work. But the stock hydraulics are shyte.
As stock the forks SAG about twice as far as they should (just under its own weight) Add some (not so fatso) meat and they are basically operating in the anti-bottom-out ultra stiff damping zone.
For we NOT SO FATTIES - there is maybe more to be gained by reducing the free air gap than over springing. Compliant at low compression but stiffens faster.
YSS I have on my Guzzi. OK but not THAT good ime. But old Guzzis have a serious unsprung vs sprung rear weight issue - The bevel box is HUGE for the power.
For asia/oz/nz there's also GAZI.
I also suggest FOURNALES - Air springs - a bit firm for some raised on cruisers maybe, but I love mine. 19bar of air is ruddy hard to compress - it is totally progressive.
