I ordered an ohlins rear shock from dan kyle for a pretty good deal lol. i've been reading about the front fork options like stoltec and some other guy from the fz09 forum but dont really feel like sending out my front forks but i may just have to.
personally found the ohlins shock to be fantastic -though i didnt compare to any other suspension offers - anything is a significant upgrade over stock.
I did a heavier for oil in the front which was a mistake - rebound (even with it dialed all the way out) was still too much and i would still get some pogoing under hard braking followed by acceleration through a turn.
I also went with .95 springs and likely should have done 1.00 or 1.05 (but my buddy who weighed less than me was upgrading and i got his springs on the cheap and figured the .95 were better than nothing).
I'm not a great rider - people could and did ride the fz09 much harder than I did but I rode my buddies bike with the andreatti (spelling?) cartridges and I still felt some pogoing in corners. The chassis to me feels like more of an issue to the handling than the suspension (though the suspension upgrades help immensely).
It really comes down to what you want to use it for - it was great for 80% of occasions i threw a leg over - it wasn't a track bike but i didnt expect it to be - still had fun at the track anyway.
I miss the power over my street triple r now but the triumph feels more composed even with stock suspension - i think part of that has to do with the chassis and better fueling too but i'm getting off topic now.
