KYB inserts to SACHS forks

[GMP]

Rob,

Don't bother with 45 Zoke parts. The uppers are prone to wear if the clamps are too tight. Plus, the KYB uppers will not fit in the 45 Zoke clamps. Start a poll on who has what and what they would like to do for an upgrade. Also look at ebay and see whats available, that should give you an idea. If the KYB cartridges are available separate and cheap let the Sachs guys know.

I am ecstatic over my KYB SS on my 2011. I am amazed how well they work compared to my 45mm Zokes. My wife just bought me some Flexx bars for an early birthday present, always wanted to try some, not sure if I will see any benifit with my new front end.

If fitting KYB internals into a Sachs outer works as good you should be very pleased.

ED

I could be wrong, but the cheap source of KYB SSS internals is primarily from complete forks on ebay from parted out blown up 250Fs. That was my point about the axel and caliper adapter. That way your not limited to the Sachs upgrade market. I would think that there are a lot more guys with 45mm Zokes looking to upgrade than Sachs. Simple production numbers. The '07 through '11 platform with a KYB SSS will give up little to nothing to a new bike. Look at Ed Ventura's thread, nice job.

I should have just done the KYB swap to my '07, still might. Flex bars are awesome! My 48s are not what you would call plush, you feel the small stuff. Thats OK though because they do not do anything bad and are stiff enough for the faster, bigger hits on the hare scramble courses. The Flex bars take the edge off them and it all seems to work out.

Glen, What coler busshings are you using on your bars

Ed,

I'm running the yellow compression and red rebound. This seems to be what just about everyone here has settled on. While I was evaluating the fork I ran red compression as not to skew my interpretation. These things are like steering dampers. You don't neccessarily feel them working, certainly not moving, but you notice when you get back on a bike without them. I've taken some big hits, and between the fork and these bars no problems.

Also, get the BRP pivoting handguard mounts, don't screw around with anything else like the Cycra.

I ran into an unseen issue. The damperod strome os too long and so is the sach lower tube.

I have more measuring to do and redesign the insert adaptor.

Well the kyb insert job is a bit more than expected. I will write a list of to do' s for this project.
I expect something by the end of this week

Rob,
Thanks for the continued effort.
It goes without saying that there are many of us out here that love to tinker, like some "custom" touches on our machines and want them to really meet our expectations for performances. Unfortunately, many of us also don't have the expertise and equipment to pull of some of the more meaningful mods like you are currently working on.
Thanks a million and keep us posted.

BTW: I have your X-Bushing on my orange bike and love it! Highly recommended to any forum members that may be hiding an orange bike on the side....

 

[Synergy-Seals]

Thanks andoman.
We have bushings for the gasgas linkages now as well.

You're not hiding it now

 

[andoman]

Nah, not exactly hiding it. Its primarily ridden by my son.

How is it all going with suspension? Ihave an 09 450 and unlike Jake i dont have the coin to drop in some ttx. ( i want to tho) Is there any others out there? Can you buy Kyb and fit them?

 

[GMP]

Search in suspension. The KYB SSS incliuding clamps from a YZF is the best way to go.

If you can mount an entire kyb front end on your gg......go for it.

My experiment is fitting the sss within the sachs fork because i came across some cc insert from damaged forks with no wheels or triples.....and because the sachs forks are extremely poor engineering and half decent when valved correctly.


So far the experiment takes some internal mods on the upper cc chamber and the spring guide ( new bushing od).
Most of all the axle insert / bottoming cone....this is total custom.

Got the forks back from pete russel at NOST. Brian Yost machined the bottom cone/adaptor insert to accept the damper rod nut at the axle....thanks Brian.

Pete did all the other mods. Quit a few at that!
I will post some pics soon.

First i need to go ride and test out petes latest technology....pretty excited.

Rob

 

[Synergy-Seals]

Well the forks were an absolute success. Pete at NOST set these forks up perfect.

Thank you Brian Yost for your help.

So I'm guessing this is no longer an easy or cheap modification?

 

[Synergy-Seals]

No. I would not advise it. Get a complete front end only. Many mods to do.....very custom

 

[andoman]

So we've come full circle.

My questions now are:
-Can re-valved and re-sprung Sachs forks be as good as re-valved and re-sprung Japanese or WP units?
-If not, what are the choices for the very best forks out there?
-If not, what then is the simplest way to achieve front fork nirvana?
-Is there a true bolt on solution?

I've searched and searched and read and read and I just end up with my head hurting....

Imho open cartridge is never as good as closed cartridge if you anything faster than slow, this is the real issue. OC CAN be made to be good enough, but will get scary as it goes deep into the stroke at pace and sits there initially at higher cartridge pressure, eg fast downhill, then hits multiple obstacles quickly and starts to cavitate and act different and nasty to normal, you lose confidence and slow down. The rougher your trails, and faster they are, the worse it is. OC are not that far ahead stiction wise anymore either. Technical slow rocky rooty terrain may give a slight advantage to OC.
