Hi guys, I'm Dave from www.jdperformanceatv.com . I am looking for any and all feedback you may have about your KFX's suspension. We are currently proto typing control arms, and the more info I can get on your likes and dislikes will better help us design the best possible product for you.
You can PM me with any input you may have, or you can call me personally @ 951-676-7957.

Thanks Guys
Dave

Junk. Sure it can hold well after taking the time to dial in but it's still junk compared to aftermarket. I've spent quite some time dialing mine in and they feel decent, but compare them to any goo dmanufacturer, even w/stock arms/swingarm, and they're still junk.

For the woods rider they wouldn't be too bad though. I probably jump a little bit into things b/c all I do is ride tracks for the most part. In the woods from what I've ridden the suspension isn't too bad but the rear shock needs work to keep from rebounding and kicking back in stock form. The fronts once broke in aren't bad there. They just can't take it on the track. But against other stock quads they're pretty equal.

I ride trails, woods and such and going fast the stock suspension blows. I weigh 200lbs and havent dialed the suspension in yet. I would say its good for jumps but it bucks.

I am 215, and race XC. I can tell you TAKE THE TIME TO DIAL IT IN. You will have to set the compression and rebound both at almost the softest settings, but the faster I go now that I played with it, the better it is. It is still far from ana ftermarket setup-but far better than any stock stuff I have ever ridden.

Not really but I only ride tracks. They seem to be able to break loose real quick but regain momentum just as fast when you wanna take off.

When I get a chance ill dial it in. Do you remember what exact or close setting you used and which way to turn the screws and which ones to turn. Never done it before on this one. Only on my yfz about 3 years ago.

Turn left to soften, turn right to harden I believe. The shocks have letters on them on the adjusters so you'll know. I softened up about 10 clicks on the rear rebound but don't recall compression. On the front I went about 5 clicks softer rebound and like 5-6 clicks on compression. Works very well on the tracks for a rider around 150lbs before gear.

My C'Dale has Fox shocks on it though so I'd like to see an lt KFX w/Fox on them. Hopefully I will for next years setup.

I'm amazed at the garbage suspension ALL manufacturers put on their quads. At 8 grand a pop, you would think we would get better than a hundred dollar shock.

c'mon now, the suspension on all of the new quads are very high quality, especially for factory. You have to remember that the manufacturer is building the vehicle to work for a very large consumer base. They are trying to please the mx,x/c , desert, trail, dune, and the weekend warrior guys all in one bike. If they built it for just one of those guys only, all of the other guys would be bitching, cause it sucks for them.
If you ask me, all of the major manufacturers are doing a pretty good job at building a quad to work for the masses.
As for the 8k price you are not happy with, consider a quality pair of aftermarket shocks to run about $1,300 for a pair of fronts alone. Thats a little over 1/8th the cost of the bike. The bike has front and rear shocks,a,linkage,bearings,motor,frame,sub frame, fuel injection system,computer,swingarm,wirering harness,4 wheels and tires, brakes,radiator,plastics,axle,fueltank,seat,cables,stem,exaust, and tons more.
So if you look at the big picture, in this day and age, you are getting alot for your money. Just my 2 cents

Give me a call, I can get you set up with A front and rear conversion for about $750.

did you really just compare the stock shocks to aftermarket? i kind of valued your opinion untill i read that...

any way personaly i dont mind the back shock but the fronts could use alot of tuning but i didnt really bother with it since ive got axis on the way.
