I rode re-valved gpx forks for 2 seasons, they worked great and held up great. Never blew a seal. I've ridden zokes, stock and re-valved. They are great to. There is a difference but not one thats gonna hold you back.
My shivers are like riding a cadillac! My GPX were not bad though butI found them to be stiff even after adjustment. I run an elka rear shock and my zokes are stock. I have never found a need for more suspension.
for my riding style i emphasise most of my riding on the front wheel and the forks are real important
a good 7wt oil change in the GPX forks make them nice and plush, that will travle through the midstroke good botton restanc. i have tryed 10wt but that makes the forks feel kinda harsh on the little stuff and harder when u over jump something. so i have found that a 7wt oik works best
i have ridden stock zokes and to me then are just a kittke to soft and would need reworked for my style
for me the gpx with a 7wt oil change are better then stock zokes IMO because i would have to redo the zokes to my style.
my setup on the gpx forks are 48mm air gap with 7wt oil, 5 clicks out on the (R) and 7 clicksout on the (C)
GPX Forks aren't bad with an oil change at all. I would not say they feel better than stock zokes though. After riding my Zokes motarding and riding some GPX... wow the zokes really shine! Of course mine were done by Velocity.
The major things I can feel between the forks is how smooth the Zokes are over the GPX. And how well they ramp up. The GPX forks do offer an inch more travel though.
