Stock Spring Rates?

[one4ale]

I poked around the archives a bit but could only find rates for the Daytona 675.
Does anyone know the specific spring rates for the Street Triples? standard & R models?

Wonder if the spring rates have been changed from year to year?

Thanks, cheers.

According to RaceTech.com...

Front: 0.850 kg/mm
Rear: 11.28 kg/mm

You are welcome. That is actually for the standard model.

The R model has the spring rates (according to RaceTech.com)...

Front: .900 kg/mm
Rear: 12.6 kg/mm

Blah, noticed this was not for Daytonas.

Yeah, but RaceTech is wrong - at least at the rear end.

Stock Street Trip has a rear spring rate of 8.6 kg/mm.
R rear spring rate is 11.3 kg/mm.
Haven't measured fork springs so I can't say if RaceTech is right or wrong.

Information I got from Wilbers matches (near enough) the Racetech figure. Wilbers tech guys said the OE rear spring rate on the R model is 126N/mm, which converts to 12.8 kg/mm (my Wilbers shock has a 105 N/mm spring).
