Suspension too loose???

Clyde Frog · June 15, 2008, 06:57:53 AM

I have an S2r 800 with the stock suspension.
When I press down on the front forks and release the forks oscillate far more than they should before coming to a rest. Since I don't have adjustable forks what are my options for fixing this. ??

Thanks for our help in advance

Most of (all) of the Ducati's are sprung for a 150-170 lb person, so depending on weight, it may need to be re-sprung.

What exactly is involved in "re-springing"?

So, I'm poking around a bit online and basically finding a lot of info on how bad the stock S2R 800 suspension is.

I'm also reading a lot about the GSXR conversion. Both good and bad opinions.
Anybody here have strong feelings on the GSXR option?

When I read your description, it sounds like there isn't enough (any?) damping. Re-springing would only help if correct the damping problem at the same time. Maybe there isn't enough oil in the legs?

Either not enough oil, or too light of oil.

I'm not sure if your problem is related, but if you didn't already read my thread, here's some info.....

+1

"bouncing" is a damping issue, and is separate (although related) to spring rates - if you change spring rates without addressing the damping you'll just end up with the same bouncing at different frequencies.

How old is the bike? How many miles? Has it ever had the fork oil changed? Are the forkseals in good condition? The service schedule for my vintage of bike says to replace the fork oil every 20,000km/12k miles - if you're a lot over that, the first thing I'd do would be get that done...

what weight fork oil does ducati put in these from the factory? I have the same bike and same weak suspension. I think putting in some 10 weight oil in it might help. Maybe in conjunction with a couple steps up in spring stiffness. Also, where are people getting springs for these forks?

I think the OEM oil is 7.5 weight.

The bike only has 4,000 miles and it's an 2007... no where near the recommended 12k miles for a fork oil change.

It sounds as though the first step would be to try a heavier weight oil. Then maybe investigate stiffer springs.

Is going to a 10 weight oil too much of a jump, too little of a jump, or just right??
