A weekend that was supposed to be raining didn't. Took a few minutes to set the suspension (baseline from the owners manual).
On previous rides the handling was ok, a little ponderous, vague front end... Seemed like it was the posture of the bike and was something I needed to learn...
Seriously, WAY WRONG.
After I set things to baseline, all I can say is WOW. "The best handling motorcycle in the world", its not just marketing. Seriously, felt so good I spent Sat afternoon and all Sun morning in the canyons laughing. The only problem now is its handles so good it feels like I'm tak'n it easy in the corners when I'm actually flying, gonna have to acclimatize to the feeling
Guess I'll have to find an R that I can transform into a track bike....

I did the same. Front end felt stiff and bouncy for break in, but I wasn't riding it hard so I didn't really take the time to make adjustments. I set mine to the base settings (front preload was WAAAY-off) and it's like a different motorcycle now. A Friend had a similar experience. It seems to me that, from the factory, the bikes didn't go out with the baseline settings. Each was different.

your bike was prob set up for either someone way heavier or lighter than you thats why you need to set it up based on how much you weigh including all of your gear

My bike handles great but I was having some head shake problems.I went i click up on the rear pre load and it seemed to help.Other than that it is base line settings for my weight as per the manual.

I backed the fork compression damping off by one turn and added a half turn of additional rebound damping. (Unfortunately I don't know how many turns out each setting is--I just adjusted from how the bike was set up when delivered to me.) That got rid of the harsh feeling from the front end when hitting bumps and cured the mid-corner wallow. I finally got a chance to really ride the 1125R yesterday and am very happy with the suspension and the bike in general. My previous big twin, an SV1000S, had an incurable (at least with damping adjustments) mid-corner wallow during tight and twisty stuff. It felt fine on high-speed sweepers, though. The 1125R feels just as good on the sweepers and much better in the tight twisty stuff.

Hmm seeing a couple things here....

1: Mid corner Wallow.
2: Head shake at speed.


Firming up the rear nixed both of these for me. I think the bike had too much rear end squat causing weirdness in the front end.

I remember that "now THIS is just right" feeling the first time I experienced it on my '09R. It came for me by going a touch softer on nearly every setting, referenced from what the manual said was good for a 165-170 pounder. It makes me smile just sitting here at my desk thinking about it ...

Ditto. In addition to your body weight loading the rear spring, the following events move additional weight onto the rear spring; engine torque and wind resistance. Increase the rear preload, step the rear spring up a notch or two from where ever it is and see if the shake doesn't occur at a higher speed.

Follow the owners manual carefully and ask for clarification if needed.

If you weigh more than 170lbs. this is all a learning experience leading up to a better spring and valving designed for your body. Same thing for the front end. I have done this to many bikes over the years, works every time.

Has the front preload been turned off completely?

They make springs for upper and lower weight ranges.

http://old.racetech.com/evalving/SpringRateCalcula tion/dirtspring.asp?brand=Buell&yr=08-09&ml=1125 R&formuse=form1&SpringType=Fork

My S1 has;
front-racetech fork springs, gpsuspension.com valving redone,

rear-penske shock with gpsuspension.com/spring and valving.

My CR has;
rear-stock shock with gpsuspension.com spring and valving.

front-gpsuspension.com fork valving. I am still using the stock front spring with the better valving I am presently increasing the preload. If that is not enough, a bigger spring will be forthcoming.
