One thing I forgot to mention.. If your riding abilities change or your desires change it's very easy to make a Khaos act like a pro (simple limiter strap change). It's still fairly easy to make a pro like a khaos but definitely more money as the front track shock will need to be changed or modified as well as limiter straps.There are a ton of 850 PRO-RMK 165's around me, but only with the 2.75. That's the path I was originally looking to go, my 850 SBA felt really close to the 9R I was riding out West, but it's so hard to tell when you're not riding them back to back and with the snow and length difference.
I think saving the $3-4k and dumping that into some clutching and potentially a different track might be a better path. At that rate I would gather the general choices are 300lx (3") or S9 (3.25")?
Yes, you're correct the 300lx or s9... I've used both on Polaris's, now both of my polaris' have s9's. Like I said before on the days that videos are made you'll want the s9. The other days wont really matter much.
