Heavier rear spring for brute.

I have determined that because I am in such great shape and have such huge muscles I need a heavier rear spring for my 910R.

After being on the track, the following chart shows I need this bike re- sprung. (no I am not the typical 180 pound rider)
Where can I get a rear spring for the Sachs unit???

Hi John,

I believe you can get a spring for most mainline Ohlins units that fit precisely. Confirm with them to double check the new 3 way but I believe this is still the case.

James, what do you mean by "3 way"

I have an Ohlins spring that I took off my Guzzi when I re-sprung that bike so I will check dimensions.

High and low speed then rebound = 3 way as found on your rear. The previous models were 2 way but I believe they kept the same spring dimensions on all models incl sachs 4way on the MT.

Ah, gotcha, I thought you were refering to the spring itself.

Airfuel - so exactly how much do you weigh in all your gear? secondly what tire pressures were you running at Mid Ohio? and what was the track temp? Did you set up your static sag f/r before you went - how much? 32mm front 25mm rear? more Less??The melt pattern of your rear could indicate wrong sag/rebound not necessarily spring rate. Lindemann are my personal favourites - everything I have everdone with them has been absolutely brilliant straight out of the box, highly recommended.

I probably am in the mid-upper 130's with all gear.
(yes I need to do this more )

I was running 33psi first session and the wear showed, I lowered it to 30 psi second day and it did not get any worse. Some say the Supercorsa pros actually need MORE pressure.
Front was 29psi at all times and is wearing nicely.

I set rear sag to 25mm front was just over 30mm.
I had to really crank down the rear spring to get that sag!!

We ran the track late afternoon early evening and it was in the mid 90's during the day so it was HOT!!!

Also, Mid ohio was just re-paved so they said it was very abrasive.

Any help would be greatly appreciated!!!
