Hyperpro on a 1050

[ES3]

Here is the first pic ever of a Hyperpro spring on a S3 1050 :wink:
I didn't drive a meter with it yet (the roads are still full of salt here ) but the looks are good, a purple spring on a black bike :-D
The front springs are also replaced by progressive Hyperpro's and other spring oil. I didn't put stickers on my bike, I don't like stickers and they don't want to sponsor me :razz:

I'll let you know the difference with the stock springs as soon I have driven with them.

What spring rates did you go with?

I don't know what you mean with spring rates of a progressive (not linear) spring? :???:

Sorry to jack your topic, but do you know if hyperpro also have a steering-damper for the 1050 S3 ?

Not yet. When they want to make one suitable (they are too busy at this moment), they'll call me again to use my bike again :-D

How do they rate progressive springs? Initial stiffness and stiffness at rated travel?

[Curmudgeon]

The OEM front springs are "progressive" dual-rate springs and the rear spring is linear, but the rear shock linkage is progressive. I don't know the rates of the OEM springs.

Is the HyperPro rear spring linear or progressive? From the part of the spring one can see, in the picture above, the windings appear evenly apaced, so it appears to be linear. Is that right? How does the rate compare to the OEM rate?

If you don't have spring rate stats, had you set the sag before and after changing springs? What were you rider sag measurements before and after? What were your preload settings before and after? The answers to these questions give us a good idea how the new springs differ from the OEM springs.

I can't answer all you questions, because Hyperpro did the mounting of the springs for me.
But they gave me a table with all the usefully values:



Please tell me the differences with original :-D
