Just found this on my computer, don't know how many of you have seen it, but I'll host it here. If someone wants to sticky it that's cool. It may be useful to many people on the forum. Thumbs Up

It gives a good base setup for loads of bikes.

EDIT-

See also this link for more suggested set ups.

How did they get these setups? Put someone on th bike and did a few laps on a tack or... what???

On another note, can someone knowledgable answer some questions for me;

What are the consequences of:
Setting preload too high,
Setting preload too soft,
Setting Rebound too high,
Setting Compression too high.

For my bike, those settings are showing, in relation to standard settings;
FRONT:
+ Compression
+ Rebound
+ Preload

REAR:
+ Compression
= Rebound
+ Preload (I actually have it +1 notch anyways)

Thing is, i find the rear is quite soft, but the front is rock hard. Maybe this is i'm kinda used to th forks on the 125, which were extremely soft. On the 125 i could pump h forks up and down easily, but on the 600? no chance.

This is why i ask the consequences of each action; i don't want to do anything that could potentially upset the handling and make it unstabl or twitchy. baring in mind i only ride on the road, not the track.

Cheers, -Nox

EDIT:
On a side note, i feel totally comfortable with the front when riding, the feedback you get is excellent. The rear is good, but a bit bouncy sometimes. I also find that when the bike is really leaned over, the rear wheel feels as if it's tracking sideways... Not quit sure if this is because i'm on the edge of my grip and it's starting to slide, or if it's just normal. I don't get the bike *that* low often, and am a bit cautious about pushing it harder when it does this.

D207 on the front with about 19mm chicken strips, and a D209 on the rear with about 10mm chicken strips. (To give you an idea of how low i'm getting it). I usually shift the upper half of my body slightly to the side, but don't always shift my arse off the seat.

These are the track settings used for the PB test track lap times table IIRC from last year. These aren't gospel, just a good place to start, the same as the manufacturers recommendations.

To be honest the best thing you can do is set your static sag properly to make sure the suspension is sitting in the right part of its stroke when you're riding and set the compression and rebound to the manufacturers spec then go from there.

You must set the sag first otherwise any adjustments you make are meainingless.

If you're really into nerding get back issues of Superbike for the past year or so they've been running a suspension feature every month, or have a look here and pay particular attention to the pre-load, rebound and compression damping bits.

Doesn't have about preload though.

How do i set the sag for my weight?

I presume that if there's too much sag, that i set the preload higher, and vice-versa.

Yes, and set the static sag to start with(the amount the bike compresses under its own weight) I wouldn't worry about dynamic sag(with you on the bike) unless you are really heavy or light.
