919 stock suspension setup

I know that this topic has been opened numerous times, but I'm wondering if anybody could share their stock front and rear suspension setup for agile commuting and a few leisure twisties.

I weigh around 165 pounds with gear on...

Thanks in advance

About all you may want to do it adjust the preload. I turned mine to 4-5. Thats about all you can do. Just ride it.

I have the same sort of Question.

Not a very aggressive rider and just bought an '02 919.

Was wondering how to make it a smoother ride so I don't feel every single bump and crack in the road? Going for comfort as apposed to "racing"

Is this just a 919 chassy thing I need to get used to or do I need to adjust the suspension some?

The stock shock is sprung to handle two riders (rider and passenger), which means it's likely sprung way too hard unless you're a big guy/gal. If you're willing to shell it out, I'd recommend shopping for an aftermarket shock. Penske and Ohlins are probably the most popular upgrades in that department.

What spring rates are in your bike? Original or aftermarket? Where is your pre-load adjusted?

So basically preload is pretty much how the bike sits when not under load (height when not under load?) and the dampening setting is how fast the suspension compresses and re-bounds with load?

Is my basic understanding correct or?

So the dampening should be the one to fiddle with when deciding how harsh/comfortable the ride should be when riding.

Preload affect ride height. So does spring stiffness. You want to set ride height with spring stiffness as much as possible and then only use the adjuster to fine tune it. There is also typically a spacer internal to the fork that's length can be adjusted to essentially change the pre-load as well.

The compression damping is not adjustable externally, only rebound. The amount of pre-load you have can very much affect the ride harshness. Having the correct spring rate with minimal pre-load necessary is the best place to start. Once that is set then you can revalve compression and adjust rebound.

Actually on your 02, the front is likely not adjustable at all. Unless someone upgraded your forks.

I have stock suspension.

So for the 9er you would only fiddle with the pre-load? Set front and back to medium for a balanced ride?

Depends on the year. in 04 they added adjust-ability to the front forks (and rear shock too I think). But your 02 I think even lacks pre-load. Look at your fork caps. What do you see?

The only adjustment for 02/03 models is preload for the rear shock. I took out all of the preload and it's acceptable. I weigh 175 and wish it was a little softer for comfort but no complains about performance.

I forgot where I got it, but I printed off a link I found on here about how to properly set the suspension for your weight. You basically sit on it in full gear with a helper and then adjust the settings so that your sag is within an acceptable range. It's a good starting point and from there, you fine tune based on feel. I'll take a look for it when I get home and post it unless someone else finds it.

Some use the weight of the fork oil as a cheap way to adjust things. Also, the oil could be pretty well worn out.

Mine's an 06 as well and due up for fork seals. There's options to change over to other valving when your in there. Not too expensive IIRC.

Thanks for all the input guys exactly what I was looking for.

As far as I can tell the rear is on the second notch. Its a red and gold shock that looks older rathe than newer. I got it off craigslist so I'm not too sure what's been done to the bike but most of it is stock. I'll put it on that first notch and see if that helps any.
Thanks again

Some stuff about the effects of different weight fork oils here, as well as some generic stuff about suspensions and how to set them up.
