Guidelines for spring rates

[dan586]

Hi, I have tried to search and find the answer myself, and have put together a rough idea of what spring rate would be best for me referencing other threads. I am around 235-240lbs naked. I ride a 05 300 with 45 shivers up front and ohlins shock. I was thinking a rate around .48 or .50 for the fork and maybe a 5.8 for the rear. My locale is the foothills of the appalachian mountains, and as such would see pretty much all varieties of terrain aside from deep sand. I do not race but would rate myself on par with a decent C level rider. Any input is greatly appreciated.

It was suggested to me- spring rates for 250# (ungeared) 6.0 rear & .50 front

From my experience, err on the stiff side with the older bikes.

I think you can find a spring rate calculator on the racetech website

I would go by what has been learned here, by riders and tuners that contribute. All linkage is different and while similar not the same, as well as general weight distribution. I'm going through this now with my bikes, and there is a big difference in what a '12 and pre '12 feels like with the same spring, IMO.
