Title: Suspension Settings
Post by: BlackNumberOne on April 05, 2006, 05:56:08 PM
This was already on the site, but all scattered around.... hopefully it will help somebody besides myself get a good benchmark or a starting point for setting up their shit.

CBR600RR Suspension Settings
Factory Settings (??03-04?? for 165lb rider):
Front standard compression setting: 2 turns out from full hard
Front preload standard position: 14mm (0.6 in) 4th groove from top of fork bolt
Front rebound standard position: 2-1/2 turns out from full hard
Rear standard compression setting: 7 clicks out from full hard
Rear preload standard position: #3
Rear rebound standard position: 1-3/4 turns out from full hard
Sport Rider Magazine (2005):
In March Issue:
Front: Preload: 11 turns out from full stiff; Rebound damping: 1.75 turns out from full stiff; Compression damping; 2.5 turns out from full stiff; Ride height: 5mm fork tube showing
Rear: Preload:  Position 3 from full soft; Rebound damping: 2.5 turns out from full stiff; Compression damping: 12 clicks out from full stiff.
In April Issue:
Front: Preload: 7 turns out from full stiff; Rebound damping: 2 turns out from full stiff; Compression damping; 2.5 turns out from full stiff; Ride height: 5mm fork tube showing
Rear: Preload:  Position 6 from full soft; Rebound damping: .75 turns out from full stiff; Compression damping: 11 clicks out from full stiff.
RRRacer:
If you set the static sag at about 28mm on the front and 10-12 on the rear you wont go far wrong.
U-235Splitter:
I am 225 lbs without gear on, I have the front preload cranked all the way in and still havve 43 mm of sag on front. However the rear factory pre-load was just fine, if I remember about 36 mm sag the race-tech guy said that thee pro-link rear works better with a bit more sag than other bikes.
Ozjack's Settings (120lb rider)(2003-2004):
Rear shock
Preload- setting 4
Rebound- 1 1/4 turns out from full IN
Compression- 5 clicks out from full IN
Forks
Preload- 4 lines showing(stock) is fine, but will need more if you are heavier(eg 1 line less showing for each 30lbs heavier than 120lbs)
Rebound- 2 turns out from full IN
Compression- 1 1/2 turns out from full IN
Swillmott82 (235lbs)
Try to get the sags set as close to 30mm front and rear as
possible.  Set rear compression at about 1/2 turn out, rebound at max or 1/4
turn out.   Front damping at about 1/4 turn out on both rebound and
compression.
DaBeachBum (255lbs)
My rear spring is pre loaded at 6 and about a turn out on both rebound/compression. It's perfect.
My front is preloaded all the way and about 1 turn out, too. It's okay but not near what i'd probably get set up for by a pro.
Ozjack's recommended settings for 180lb. rider (2005)
Set the preload properly for starters, should be setting 5 at the rear shock, front forks standard should be just about right for your weight judging by the stiffness of my mates 05.
Add a full turn of compression on the forks, and 1/2 a turn of rebound.
Rear shock would probably need 3/4  turn more rebound, and maybe 1/2 turn compression.

MCN Magazine (2003-2004)
10 stone (140lb) rider
Front Preload = flush with 4th ring from top
Front Comp. = 1 turn from fully in
Front Rebound = 1 1/2 turns from fully in
Rear Preload = Position 3
Rear Comp. = 2 1/2 turns from fully in
Rear Rebound = 1 turn from fully in
14 stone (203lb) rider
Front Preload = flush with 3rd ring from top
Front Comp. = 3/4 turn from fully in
Front Rebound = 1 3/4 turns from fully in
Rear Preload = Position 3
Rear Comp. = 2 turns from fully in
Rear Rebound = 1 1/4 turns from fully in
Standard Settings should be
Front Preload = flush with 4th ring from top
Front Comp. = 2 turn from fully in
Front Rebound = 2 1/2 turns from fully in
Rear Preload = Position 3
Rear Comp. = 2 turns from fully in
Rear Rebound = 1 3/4 turns from fully in
Hollywood's settings (145/165lbs w/ gear) (2003-2004)
Front:
   Preload:  3 lines showing
   Rebound Damping:  1 turn out from full stiff
   Compression dammping:  1.5 turns out from full stiff
Rear:
   Preload:  4 of 7
   Rebound Damping:  .5 turn out from full stiff
   Comp Damping:   6 clicks out from full stiff
RONS Settings (215lbs) (2003-2004)
The magizine article recommends 20-25 millimeters of sag. Closer to 20 for the track and closer to 25 for the road. I'm running mine at 28 front and rear. At 215 lbs I need 3 rings in the front showing and position 5 in the rear to get that 28 mm.
BIKE magazine (setting sag) (all bikes)
They recommend that the static sag setting should be one third of the suspension travel. For example, if you have 150 mm total travel with the suspension fully extended, then with the rider and their gear on the bike, 100 mm of travel should be left. Just another option for setting your sag.

no problem man.... i was doing it for myself and figured it may be "the thread" that helps someone else get through some suspension tuning. I've been trying everything just to get a better grip on how the adjustments make the bike ride differently. Only reason i'm being brave now is b/c after i throw a 190 on the back, i'm going to have it professionally done anyway. its experimentation time.

Do you think riders would have to give way too me if I painted the tips of my forks red, like a red tipped cane??

05 onwards have upside down forks, and revised rearshock settings(compression is 12 clicks out instead of 7 as on the 03-04).

Any one have trouble adj preload on the 2007 CBR600RR rear shock. I cant get the thing to budge even with a spanner wrench.

Also, any know how to get the bike about an inch lower
Title: Re: Suspension Settings
Post by: maskale on January 24, 2008, 05:12:08 PM
it is tough to move, the wrench I had came with a small extension, even with that it took some effort. Shock it with a sharp blow with a screwdriver. After it moves the first time it usually moves easier.
Title: Re: Suspension Settings
Post by: Ozjack on January 26, 2008, 12:00:21 AM
The rear shock is stepped-preload, meaning it will snap to the next setting and skin your knuckles.
Setting the preload properly front and rear will lower the bike a decent amount, but if the bike can`t sag enough with (her?) weight on it then it is best to buy new, softer, springs.

Lowering the bike any other way is just asking for handling problems, and can have detrimental effects on the current spring rate too(if you change your linkage).

The shock may move about a little while you adjust the preload, this is normal. :thumb: ;D

are there any 'advised trackday' susp setting know for the 07-08  600rr ?

I just can't get the tire wear to become in a proper way.  A LOT of rubber parts on the side of the rear tire.. tried out several comp and damping positions but nothing seems to help  ???
Title: Re: Suspension Settings
Post by: Ozjack on May 02, 2008, 09:53:49 PM
If it's the rubber balls on the tyre's edge you're talking about I don't think suspension changes will make them go away. The more you open the throttle the less balls you will have(contradictory? 8)). Tyre spin is the only way to have clean tyres at the end of a session. I don't mean sideways out of every corner, just coming very hard out of corners will have the tyre spinning gently but not stepping out, you may not even feel the spinning tyre at all but you will have clean tyres.

If they are wearing dramatically then yes, maybe you need a softer set-up.

Yes, i was talking about the rubber balls.  Will definately try to open up the throttle a lot sooner than i use to do  :)

Are these settings for track, or for street use? I'm 6 ft 195 lb. I was wondering if the 200lb setup would be appropiate for average street riding, and rare joy riding?

I've got some baseline stuff for my 07... however unless you have a Penske triple clicker shock and AK-20's in the forks it won't do you any good...

Post by: excat on April 27, 2009, 02:48:40 PM
Jason, the settings on here for roughly 200lb (2003), are those a track set-up or for street?
Title: Re: Suspension Settings
Post by: Jason748 on April 28, 2009, 12:58:10 AM
Pretty much street.
Really the biggest issue with the 03/04 (and even the 05/06 & 07/08, but to a lesser extent) is that the stock front springs are about right for a 130lb rider...  it' OK on the street but could be better with a simple spring change.

The first thing I'd do when setting up a suspension, street or track, is set the sag correctly.  Because if the sags not close, adjusting anything else is pretty pointless, IMHO.
Title: Re: Suspension Settings
Post by: excat on April 28, 2009, 02:04:04 AM
Alright, thanks Jason. I'm sure I'll have many more questions for you, if you don't mind! My suspension is way too soft for me, and I want to learn to do it myself.
Title: Re: Suspension Settings
Post by: Jason748 on April 28, 2009, 10:29:31 AM
Not a problem, shoot away...
But just a disclaimer - I am in no way, shape, or form a suspension guy.

Here';s a "how-to" on setting the sag for the front that I wrote up a while ago:

OK... Here goes.  This is how I "base-line" my front sag (preload) setting, this may not be where I end up after adjustments, tweaks, etc... but this is where I start off.  I am describing this based on using USD forks (05 - current), but it the same process on RWU forks (03-04) you just take the measurement in a different place.  It's really, really handy to have two friends to help you, one hold your bike one to take measurements (have him take ALL the measurements for consistency).

WARNING:  THERE WILL BE MATH INVOLVED, but no test  8)

Forks:
1 ) Place a small zip-tie on one of your fork tubes, this is what you'll be using to take measurements from.
2 ) Get the front end up in the air so the wheel is OFF the ground and the forks are completely extended. (any "under the tree" or "steering stem" front stand is what you should be using)
3 ) Slide the zip-tie all the way up against the seal and take a measurement from the bottom of the zip-tie to the top of the fork bottom.  We'll call this measurement FL1 - Write it down.
4 ) Take the bike off the front stand (and off the back stand too for most accurate measurements).
5 ) With full gear on, sit on the bike in your normal riding position, this is where you want to have a friend to hold the bike up.  Firmly push down on the bars to compress the suspension a bit, then gently let it come back up and settle (all while your still in your ridding position).  Without compressing or decompress in the fork, slide the zip-tie against the seal.
6 ) Take a measurement from the bottom of the zip-tie to the top of the fork bottom.  We'll call this measurement FL2 - Write it down.
7 ) While still sitting on the bike in your normal riding position, with your friend still holding the bike up.  Firmly pull up on the bars to decompress the suspension a bit, then gently let it come back down and settle (all while your still in your ridding position).  Without compressing or decompress in the fork, slide the zip-tie against the seal.
8 ) Take a measurement from the bottom of the zip-tie to the top of the fork bottom.  We'll call this measurement FL3 - Write it down.

Now you have three measurements FL1, FL2 and FL3 and your probably asking yourself:  Well :-X do I do with these now?  I'll tell you:
You plug in the numbers you've written down into this formula:  FL1 - ((FL2 + FL3)/2)  and presto you have your rider sag distance.

So, to plug in some real numbers in for example:
IF:
FL1 = 139mm
FL2 = 110mm
FL3 = 116mm
Then the formula should read:  139 - ((110+116)/2)
First do the addition and you get: 139 - (226/2)
Then the division and you get: 139 - 113
Now have your sag measurement:  26mm

Now depending on what you are doing, you'll need to adjust your preload adjusters and re-measure (FL2 & FL3 only, as FL1 will not change) to get within a "specified range".  I'd recommend shooting for the following numbers to start with (remember these are just starting out numbers).  Depending on your riding style, and comfort range, you may need to go with more or less sag.
Now the the 2005 - 2007 has 120mm of front suspension travel, so:

Street: 34mm - 38mm (approximately 30% of travel used)
Aggressive street / track day: 30mm - 35mm (approximately 27% of travel used)
Race: 28mm - 32mm (approximately 25% of travel used)


Ideally you want to be in the middle of your adjustment range when you get these numbers.  If you just flat out can't get them, or you are close, or at the end of the preload adjustment range (either full hard or full soft) you really need to get the forks re-springs for your weight - talk to a reputable suspension guy about this!

And that is how I baseline my front suspension sag setting.  Anything else while I'm at it?

Disclaimer:  I am in no way, shape, or form a suspension guy... I highly recommend you talk to a REAL suspension guy (like, Rob @ Lithium).


Setting the rear sag uses the same math, but you need to measure from the axle to a point on the sub frame vertical from the axle.

Would the outside temperature effect my measurements? It's been cold here the past week. Didn't know if the oil being cold would give me a different measurement than warm oil?
Title: Re: Suspension Settings
Post by: Jason748 on April 28, 2009, 02:05:17 PM
Not enough to worry about for setting sag as you're measuring and setting the spring preload, which doesn't really factor in the oil.

Unlike adjusting the compression & rebound which are tempature senesitive, to a point, becuase you are adjusting the rate that the oil flows through the valves.
