I'm going to check mine. It's stock but seems really stiff. Be nice to see what works for other folks. Be good to state your weight and what kind of riding you do.


Thanks, Dave

That question has prompted no small discussion, but the factory settings are a good place to start. "harshness" could be related to compression set too high. The table for a 2008, by weight is here (bottom of page):

Not sure if 09 and 10 models were the same, but you can check Owner's Manual link at top of BW pages.

i big reason for that is because you have an 08' and all the way until the LATE build date 08's had stiffer springs in the forks, but were switched to a softer spring for LATE 08's- 10'

my 08's a little stiff too, but i dont mind lol

I can't imagine a stiffer spring! Harshness could also be from to much rebound damping. Anytime you reduce the amount the suspension will travel, it will feel stiffer.

I have an 08, built in the first week of production November 07.
I set mine to the book then went a clik softer but not to the soft-limit.
I'm lucky if I hit 160# with gear and it rides very well.

It IS a lot stiffer than my Uly, but I expect that.

Set Sag first...then play with dampening....a properly set up sport suspension is a bit harsh on the street.

I tinkered a good deal with mine early on, ended up being happiest with the factory recommended settings across the board, just one step softer. I've since gone up (+1) on the front preload to get rid of rear tire spin ...

Ridenusa - what was the approximate build date when the fork spring change was made? Thanks.

The change over occurred in July, 2008. You can also tell by looking at the fork and shock part numbers. If it ends in .1AMA then its an early version, and .1AMB is the later version.

I was not very happy with the handling of my CR after I bought it. Fortunately I picked up a mag (Sportrider, Motorcyclist?) that featured a comparo of the CR against a base model Duc Streetfighter. I thought it made sense to replicate the magazine's recommended settings and whammo, the bike was totally transformed. It behaved beyond my expectations, most of all I had restored confidence in the suspension. I looked around for the magazine and can't seem to find it at the moment. I highly recommend the settings, at least as a baseline starter setting. With me it was plug and play. I'll continue to look for it, but likely someone here has it.

The one negative I recall, was the rear shock adjustment. It was one of the adjustments, maybe preload that hit the max click setting on the mag's suggested settings. That meant no more room after that, I didn't like that.

Johnnys999 - when you run out of pre-load and want more you buy a stiffer spring. A really smart move is to get the shock valving tuned for the new spring.

I found the settings in the 12/09 Sport Rider magazine. The figures are on their website.

Now that I found it I remember it was the rear rebound damping not the preload.

Johnnys999 - A really smart move is to get the shock valving tuned for your spring.

Do some research/get an education, talk to some suspension tuners about shock valving.

Dave at GPsuspension.com is a Mechanical Engineer his company produces the internals for motorcycles with CNC machines. 'A' team racers use factory tuners and components. 'B' team racers use Ohlin, Penske grade shocks and tune using GP suspension shock and fork components from valving to oversize cartridges....

Yes, good advice if I were going to keep the bike.

I'm really after a good set up for more comfortable street riding. Then I can always stiffen it up for a agressive track day.

Johnnys999, Watch the settings in sport rider! The one where you move your fork tubes flush with the top tree, or something like that it can be a rude eye opener!! Go in small amounts and see how you like it. I made the full change and almost put it down a couple of times. I went back halfway and it has been there ever since. Just my 2 cents, hope it helps

i had mine set up at a track day by 100% suspension, for anyone interested this is how its set at the moment
front 23mm sag, comp 2 1/2 turns from fully in, reb 1 1/2 turns from fully in
rear 6mm sag, comp 13 clicks from fully in, reb 1 1/2 turns from fully in, i didn't mind messing with the suspension set up on my mountainbike but i don't really bother with the 1125, it seems ok to me
