Suspension settings... - Ducati.ms

isse · Sep 12th, 2007, 2:07 pm

Anyone else who has messured there bike the Öhlins way and care to share there findings?

I messured my Bike last week and did some tweaking of the pre-load today and remessured.

My values were all on the soft side (after adjusting all values to standard) so today i gave it a extra turn on the front preload (standard is 3 turns from full soft) and aprox half a turn rear preload.

After this my rear seems better, but the front is still a little soft, so will add another turn tomorrow and remessure.
Whould be cool to compare if any other people have checked there settings.

Ahhhh the suspension thread........

Suspension is such an individual rider thing that its hard to say what is right for you is right for me. I guess that is why we can adjust it huh. Although I don't have the Ohlins rear I finally started tweaking with mine a little and won't really be able to say how it handles until I log a few more miles.

I set the rear at about 32mm of rider sag for now which only took less then a 1/4 turn on the spring for the standard(s) rear shock from factory setting. I only have about 3mm of static sag now however. (It was at about 5mm before I made the adjustment.) I think between 30-40mm of rider sag will give about the best all around performance for street and light duty track use. I know that they usually say to have between 5-10mm of static sag but not sure I can achieve both with the standard(s) shock.

The Ohlins should be able to be dialed in pretty good I would bet. I'll ride it for a while and see how it goes.

As for the front I got the zip ties on the forks now to see where I'm at with them. I went out and did a stoppie and some extreme braking to see how far down I could push them and they where 30+mm shy of bottoming so I have plenty of room to work with there. I tweaked them slightly, we'll have to see with some more riding.

My suggestion when it comes to adjusting suspension is to go slow and make sure to mark where you started or know how to get back to that point.........or better yet hire an expert if you got the $$$$$$$

I very much agree with you that the settings are idividual, but it´s still worht while to know how others found the standard settings and how they have managed getting it tuned.
Everyone should at least messure up their bike to know their in the ballpark.

Im a little confused on your rear sag, did you have 30mm without rider and 32mm with ? sounds like you are a very light person :-)
My rear after almost half a turn is now at 5mm static sag and 37mm with rider.
The front is still a little soft me on and i will tune this again today and report back.
Btw i weigh 75kg.

My bike didn't have any sag when I got it, and almost none when I sat on it. Had to take a few turns off the rear, and the bike handles a lot better now. I'm still not sure what to do with the front, I'm used to long travel front forks on my other supermotos. When I pull the front end up and chop the throttle, I bottom the forks. This may be normal, and may have to keep some throttle while coming down. I only weigh 150 lbs, and thought that the suspension would handle it a little better, (50mm). The bike takes the bumps very well, and handles rough corners very well too. Would like to know if this can be adjusted out, or if I just need to re-learn how to wheelie!

Isse,

Actually I am not that light, about 175-180lbs and I'm not sure I understand your question or we are having a little breakdown in communication. So I'll just give you the numbers again at present the bike has 3mm of static sag (no rider) with rider I am at 32mm of sag. I think maybe you just didn't read or understand my last comment.........

Hehe, the thing i reacted on was that you only had 2mm om difference between rider and no rider. that is very minimal.
From the factory i had 25mm differance between rider and no rider and i think that will be the case after adjusting also.

First of all messure up the bike and se where you are at (first put everything to the standard setting) and then from there adjust the preload untill you are in the ballpark, or as close as possible. Slamming down the front from wheelie is never a good thing though! Always meet the wheel comming down with some acceleration.

that little static sag tells me that your springs are too stiff. at 175 - 180, I have no question that either your springs are too stiff or you are too light.

Buck,

You realize that by static sag I am talking about the bike only. No one on it. Either that or I am misunderstanding your comment because my weight has nothing to do with static sag.

It was at 5mm when I got it and after making a slight adjustment it is now at just over 3mm. I have 32mm of sag now when I am sitting on the bike in a riding position.

sorry to confuse you- yes, I do know what static sag is.

Here's a link to Ohlin's sugestions on setting suspension: http://www.ohlins.com/Motorcycle/Set...9/Default.aspx

They suggest (for the front) 15-30mm static sag, and 35 - 50mm with the rider. If you have your sag (with rider) set at 32mm, then you get off and you only have 3mm of sag, then the springs are too stiff for your weight. That's standard for Ducati. my guess is that your ride is pretty harsh.

If the springs were light, you'd end up with 32mm of sag (rider on) and something like 29mm of static sag - excessive preload would make up for the
low spring rate and the ride would be terribly soft. with little travel.

heavier riders require heavier spring rates. lighter riders require lighter spring rates. suspension is all about compromise if you're not going to have it re-sprung and revalved for your weight and riding style.
