Isn't static sag how much the suspension compresses under just bike weight? If it is, that's not what I was talking about. I was talking about the length of the suspension when fully extended, i.e. all weight taken off suspension components. That's what all suspension guides tell me to measure and I don't understand why you can't know that based on what suspension part you are using instead of having to measure it?

Ok, here's an example of what I'm talking about. This website gives a front travel distance of 120mm for the front forks. So, why do I have to lift my bike off the suspension and measure it, instead of just using 120mm for my first measurement?

i agree with you there, just take 120mm and subtract from there. If you setup up a stock suspension of the same bike and same model all day long, that's fine. But all the general suspension guides don't deal with the same suspension, so they tell to take that extra step to get the correct measurements. I would trust my own eyes more than what a mag tells me, there are no short cuts in life.

Ok, static sag is as you rightly say from topped out to bike sitting stationary without the rider.

Why do we lift it? Because we need a consistent datum to measure from, topped out will. Not change, however if u just measure with the bike sitting on its rear stand the forks will be compressed slightly which will give you a different final measurement for riders sag.

As you say we have 120mm of travel, but this is not consistent, air gap and other variables can change that... What we are looking for is the fork to be in its mid stroke at the apex of the corner as the rider moves from off to back on the power, too far up the stroke means the bike Will run wide.

So, we lift the bike to get a repetitive datum to take all other measurements from, otherwise the forks or shock can be compressed which can mean a variable of up to 5mm in setting riders sag..

Hope this clears up the difference

Bowdy, great post! easy to understand for the layman......thanks for taking the time to put it down.

Quick question for you - the base shock. Is it worth trying to get this working or is replacement the only real way to go?

Have been looking at replacing with a ttx mkII or a mupo unit. Both similar price - but no one seems to have used the mupo.

On the set-up side up side of things this article is worth a read - from Bursi in Italy - doing some pretty tasty mods and testing on the pani. Jerrys worlds: Bursi Panigale development

Hootsman, don't waste any money or time on the stock rear shock, on other posts I've qualified that its not worth the money ducati spent on fitting it.

Now, either of the shocks you've looked at are worth considering, as is Penske, I actually ordered a TTX and because it was delayed in shipping to Aus I modified my Penske units from the Yamaha R1s we raced in ASBK and the Aus endurance series, fitted and working a treat... It's more about getting any of them set up for your riding, the challenge you will have is knockhill is so very bumpy and tight which is not ok for setting up any bike... But uv got great roads up there...

Plenty of good suspension people over in the uk... So make sure who ever sells you the shock is fitting the right spring and valving...

Cheers
Thanks from veck

Ahh!! Stoner! The other white meat!!!


Interestingly enough Stoner is already rubbing the V8 drivers in the Aus series up the wrong way... Except the boys in V8's will just punt him off the track in a heart beat...

Plenty of stories going around the Australian paddock about him snubbing younger riders and being a complete dick... Amazing how a bit of fame can make people become bitter...

I know a lot of the English guys his family spent time with in the uk... How different he is to Troy Balyiss...


Still only my opinion... Like asses, everyone has one... ;-)

Amen on getting the right springs for your weight and riding style.

Dropping down to an 8.5 spring in the rear and getting the rear ride height correct made a huge difference for me. It calmed things down and lets me work with the bike instead of fighting it.
