230lbs and yer got the sags correct with the standard yamaha springs....

35mm static " bike under it's own weight "
33% rider " with rider standing on the pegs "
Sitting moves the rider weight bias rearwards and ligthens
the front...

I'm with Petenz here. My shock was nothing short of dismal - springing too soft and very under-damped.

Best thing I've done to my bike: an Ohlins shock.

I was considering to change my XTZ-08 (30000kms, Owened from new) for a KTM 690. Basically because of the poor Off-Road behaviour (I work as Bike mechanic and rides different bikes every day).

But a change like this is quite costly: Either I by a new bike, knowing there are no problems from poor maintenance ot hard riding or I by a used one with risk of the above ( I see to many used 1-2 years old, 3000 km bikes that are badly worn..)

So I decided to spend money and bought the �hlin shock and fork springs wich I just installed.

Test run Gravel road and offroad: I've got a completely new bike! It feels small and flexible like my 250 KTM Enduro.

So in comparision with the cost of buying another bike I must say that the ~ 1000 EU I spent on suspension was cheap!

I also just learned that there is soon an Cartridge Emulator soon available for the XTZ.... just waiting

Hi Mudcrawler,
Which emulator were you waiting for? Who is making one for the xtz?

I am using the V4S valves (emulators) from Teknik Motorsport in Australia on my XTZ. Can't fault them. An infinite improvement over the stock damping.

I bought a yss rear and hyperpro with heavier oil and a spacer. The yss has been great and took some real hammer. Night and day in performance both on and off road.
Cheaper option yss than ohlins by quite a margin too.

Very good. I have the abs model, and I'm not sure they supply shocks for those. what I saw from Teknik said no abs...... That was the Yacugar ones.. Guess I'll just have to ask them.

What would you suggest that I do with the rear suspension? A totally new one? If so - what brand is recommended? �hlins, Wilbers, Hyperpro etc?

And what about the front? Will new springs and oil do the trick? And what brand do you suggest?

Thanks in advance!


For overlanding reliability usualli us is a focus point. So for the rear shock i would definititely recommend a shock with a gas reservoir. (see example of different types http://hyperpro.com/shocks/ )

The entry level aftermarkets are emulsion shocks, are not so suitable for race of offroad use. Shocks work harder under these conditions. Emulsion can't cope with that.

The advantage of a shock with a gas reservoir is that the temperature stays lower and the internal pressure is lower, which in turn prevents your seals from overheating and crapping out.

Another advantage is better damping charactaristics.
Disadvantage is the higher price.

But for overlander, i'd spend some extra if you'll be living in the bike... :)

For the fork i think a nice start will be springs and oil depending on your budget you can take it from there.

Thanks for the advices. However my questions about suspension was posted about two years ago and upgrades were done just a few weeks later. Did new springs and oil in the fork and new rear shock - but without a reservoir. No point throwinh pearls at a pig....
Found it to be adequate improvements.

Hi @nethen, which shock from YSS did you installed on your xt660z?
How is shock's performance after 2 years?
