very sick, but to the average motocrosser such as myself, im not going to go by 2011 bike because of forks..... im sure i wouldnt be able to tell a difference between the 2011 and my 2009.

I'm not sure about that. You can always tell when you have a freshy underneath you.

I was wondering if they got a patent on it? As Honda did the SOHC.

if it has already been done in mountain bikes as they said....they would qualify for a patent!

Marzocchi also had forks with a similar design years back .

i doubt the average rider will even notice the difference. most reviews from top riders did not say much other than it is easier to setup.

Will you notice a difference. I am sure. Will it shave lap time's? Maybe.

Ok Bobby, here's the trick.

Take your 09 KXF and buy a fork spring twice as stiff as you need. Then remove your old fork springs and replace with just the one stiffer spring and there you go, your red-neck 2011 KXF.

Let us know how it goes...

I have been told buy a few suspension guys that the 2011 forks can't be used for sx. There's an aluminum part on the compression side that can't handle the hard stiff jolts from sx. After about 6 laps it breaks. In the pic you can see it on the top of the fork on the left side.

compression stacks are on the right side (facing us). Is this what youre referring to?





hitting square edged holes at 50mph outdoors stresses compression circuits more than a triple face.



"suspension guys" ? can you elaborate? showa engineers?

The aluminum tube at the top of the left fork looks like a preload spacer for the spring. I'm going to speculate that the problem they are talking about is that if you put in a spring stiff enough for SX, big hits will then overwhelm the spacer and deform it. Weakest link kinda thing. Makes sense since all the load is on one spring instead of two. I wonder if anyone has tried machining a stiffer spacer to overcome this?

3 weeks? how many rides is that? how many different settings can you possibly try in a handful of rides. Generally, stock bikes wont be set up for A riders anyway (bell curve).

I think thats throwing the baby out with the bathwater there. A riders should know how to read a service manual and set their own suspension. Oil level/spring rates/compression washers/etc. all will make a world of difference. there's no telling what the potential there is if you dont troubleshoot.

Well said. I have an 11' kxf250 and the forks were a little overwhelming at first to say the least. If you're a guy that is used to sending your suspension out to have it done and you keep getting it back and its not to your liking, then yeah, you're probably going to get frustrated and just give up.

I like doing the adjustments myself and I have read the suspension part in the manual numerous times and it took me MANY days at the track to finally get it somewhat figured out and to my liking, but now that I have, I love the suspension and really have no complaints. I'm not a pro rider by any means, I race 30+ int class when I do race. But from what I have gathered, the people that are having the most problems with this suspension (and I'm not talking pro level) are the guys that dont take the time to actually read up on it and make the proper adjustments themselves.

Like no one has the capability to simply machine and exact copy of that preload spacer out of ti. ss, thicker aluminum, steel, or whatever.

Don't be ridiculous.

Go ask P.C.

Are they "Believers"?

I've seen these things get removed and put on the shelf on other teams.

I'm jus' sayin'...

The feeling I got in talking to them was that they felt they were already on par with what they'd been using, but also had a lot of upside potential.

the guy who sold it to my friend played with that bike for hrs upon hrs before offing it....watching him ride you could see he had zero confidence in the bike just because you can adjust it dont mean u can make it the way u like with oil levels washers etc...he dident want to chase it so he got rid of it for a leftover honda 250...cpl clickes on the forks and shock and he likes it much better ....every rider is diffent .. 1 other guy i know put his 2010 forks and clamps on it said its perfect like that

I think it's a garbage concept and you won't see it around long.

Weight savings are minimal and one side must be overbuilt to compensate....they got it wrong and the forks are breaking. Worst case scenario.

Similar to what Dick's Racing in Roseville, Ca has been doing for years right?
