Can't compare the ES with the Gen 3 A, but as 15wannabe says, the handling of my AS is much, much better than the Gen 2.
When I first got mine, I found it very harsh. Over the miles, it's become a bit better (or I've grown more used to it). I do believe it's oversprung for my weight (145 or 150 pounds depending on what She's been feeding me).
But the confidence in its handling is well worth any discomfort. Yes, I have played with the suspension settings and do change them according to conditions, soft is reserved for slabs, standard for most riding, hard for twisties, particularly if the road surface is less than perfect. Apart from initial experimenting and once when I took a passenger, preload remains at rider only.
OEM tyres, BT023F, have been very satisfactory. Rear replaced prematurely after a puncture, front still on at about 9000 miles, beginning to show signs of needing a little bar pressure through turns (but nothing like the old BT021 after 3000 miles!). It's almost due for replacement, just about down to the wear bars. Rear replacement is a BT023 (not F, not GT), I'll replace the front with a 023 or T30.
Hey, wannabe, you'll have to change your name. 15happychappy?
