What spring rate for XR650r.

I've gained some weight and am wondering what the recommended spring rates are for my weight.

I'm 215-220 out of the shower plus boots, gear, day pack with tools, water etc, dual sport kit on bike with 4.7 gallon tank.

So I think I'm about 240 dress to ride with backpack etc.

My current spring rates are 10 shock and 45 for forks.

Any suggestions?

I'm 215 nekkid and run .50 in the front on my XR-R Motard/dirty bike. They work for me.

10 in the rear too. I re-valved my forks last year. Big improvement, but still not as good

as a professional job.

I'm 235 buck naked and i'm .48 front and 11 rear.
I'd prefer 10.5 rear.

If your just buying the springs and doing it yourself ask the supplier for recommendations...I used a company here in the Uk and they said 0.49 front and 10.5 rear for my weight 230 without gear.

My thoughts were 0.47 front and 10.5 rear and by the Eibach charts!

The 0.49 fronts are what the motard guys...

Im glad i got the 0.49 fronts as the combination with the 10.5 rear is superb with the bigger clarke tank occasionaly fitted somthing we all forget about!

To overcome the additional stiffness of the 49s i used 2.5 weight fork oil the ride is simply brilliant!

If your doing more Ds work and loading the rear then perhaps go 11kg hope this helps...
