Funny I just ordered a pair of .95's for the Strom yesterday, and I played with the calculator some, changing the bikes and my weight five or six times to see the result, it worked fine for me.Good deal. Glad to help.
Just my opinion.......lots of folks apparently like the Sonic spring but if you put 115 lb rider weight or 315 lb rider weight the Sonic calculator recommends the same 1.2 kg/mm spring. That dog won't hunt.
Race Tech's calculator gives a wide range of spring rates based on different rider weights which makes more sense to me but use what works for you.
Try it with the ST1300 and see if that changes the recommendation.Funny I just ordered a pair of .95's for the Strom yesterday, and I played with the calculator some, changing the bikes and my weight five or six times to see the result, it worked fine for me.
One thing I did notice is that all the fields must be filled in to get a response. :capwin:
I can't wait for them to arrive! What setting did you settle on for your rear preload adjuster after you changed the front fork springs?I put in a set back in Jan. I needed to replace my fork seals. I hope you like yours as much as I like mine. I wish I would have done it many years ago.
Just tried it. 1.2 whether I was 150# or 220#. Not sure how they can recommend a spring with that calculator w/o knowing what bike it's on.Try it with the ST1300 and see if that changes the recommendation.
There is no hard and fast rule for setting rear preload. Some people may prefer the quicker turn in that lots of preload may give providing the shock spring is good for their weight. Using sag numbers can give some objective targets for preload. The rear spring on the ST is fit really for only the lightest of solo riders. Heavier riders need lots of preload to hit decent sag numbers and this tops out the spring when the bike unloads the suspension. FWIW I once made a chart that correlated my rider sag with turns of preload and lines on the Showa adjuster. After time though I just know I like about 7 clicks when unladen and chillin, about 10-12 if unladen and riding in a sporting manner, adding more clicks if packed for a trip - adjusted for chillin or hauling the mail on tight roads. I weigh about 150-155 in street clothes and 20 more in gear. A heavier rider would need more clicks to equal the same sag.I can't wait for them to arrive!

Just curious
I never touched it. I'm probably 3/4 hard. It is a little stiff. But it is smooth as can be when I'm loaded. I just keep it that way.I can't wait for them to arrive! What setting did you settle on for your rear preload adjuster after you changed the front fork springs?

I went with:Thinking about going to 1.2 sonic springs.
Will be keeping oem rear for now.
230lbs
What spacer length
What oil depth
What weight oil worked for you?
Remember I am still using the soft oem spring.
Thanks
... you are talking about your... huh... suspension, right?I never touched it. I'm probably 3/4 hard. It is a little stiff. But it is smooth as can be when I'm loaded. I just keep it that way.
Made the change about 6 years ago, also went with 1.2 Sonic Springs, 140mm spacers, 125mm oil level, 7.5w fork oil (50% 5W / 50% 10W), stock rear spring at full preload. I'm also at 220 lbs.I can't wait for them to arrive! What setting did you settle on for your rear preload adjuster after you changed the front fork springs?

Yes!!! I'm talking about my bike.... you are talking about your... huh... suspension, right?
I have the racetech .95, with this setup I did a full blown hammer to the metal panic stop. So much the abs kicked and I swear I did a stoppie. My helmet hit the windshield and broke my sunglasses inside my full faced arai helmet. But the bike stopped clean and straight on a down hill slope with no avenue for escape. I do not think I could have done this with the stock springs.Made the change about 6 years ago, also went with 1.2 Sonic Springs, 140mm spacers, 125mm oil level, 7.5w fork oil (50% 5W / 50% 10W), stock rear spring at full preload.

Amazing improvement, the ride will seem a bit stiff at first, compared to what your coming from. You won't realize the full potential of the change until you make your first panic stop!!.
Last year I put a Racetech rear shock on, I should have done that sooner.
Quite possible with stock springs with the correct preload.I have the racetech .95, with this setup I did a full blown hammer to the metal panic stop.

Possibly if you weight a lot less than my 220 lb pork lined body.Quite possible with stock springs with the correct preload.
