Track Base Line Suspension Settings

[JBuchanan]

I am about to pick up my new BMW S1000rr in the next week or so and it will be going straight to the track. I have been sifting thru tons of threads on suspension set up and I know it depends on the individual rider/style/track conditions/weight/etc but I would like to get a baseline to be able to optimize my track time. Any help is appreciated.

This set up would be for stock suspension to hold me over until funds allow for the Ohlin 30mm kit and TTX shock.

Rider: 210lbs w/out gear; has trackday/amatuer racing back ground

1. Sag
a. Front: 30-35mm
b. Rear: 25-30mm

2. Ride Height
a. Flip Eccentric Washer (raises rear) - does anyone have a link with step by step directions?
b. Fork Tubes – 8mm above triple clamp

3. Front
a. Rebound – 9 (1 from max)
b. Compression – ???

4. Rear
a. Rebound – 9 (1 from max)
b. HS Compression – ???
c. LS Compression – ???

Thanks in advance!

Just my two cents, but before you play with the geometer stuff (ride height) adjust the sag and try it. If the bike doesn't handle, then start changing.(one thing at a time)

Have you considered just going to Ohlins suspension as your use looks to be track?

The rear spring is too light for you.

The front springs are too light for you.

The forks will dive a lot.

The stock forks have a lot of friction as well.

The rear shock, as you adjust the rebound, also effects the compression.

We shoot for 38 to 42 MM front sag
and 28 to 32 MM rear sag.

Now you can get to these numbers with the stock springs, but that alone does not mean the springs are right.

If you take a soft spring and put enought preload on it you can always get to whatever sag number you are looking for, but it is still not right.

Dan....It is difinitly in the plans for the Ohlins! But I need to do one step at a time. I will most likely be placing a order with you for the Ohlins set up, but would like to get initial set up info for the interim. Being overseas (Air Force in Italy) there isn't a local company I trust, so I will be reaching back to the states for help/set up. I will start with your initial suggestions as I know your wealth of knowledge will come in handy!
