Maybe I'll just get the front resprung and replace the rear shock (I don't think it can be resprung?)
Actually, the fact that the Bitubo Cartridge Kit utilizes linear rate springs is not such a huge deal. Preload in fact does cover a somewhat wide weight range. And when it comes to the cartridges themselves in this kit, they are also very beefy in design and will handle damping well for a wide range of weights. If you want a system that is exactly tuned to you, then you'll be paying $2000 for a custom design instead of $525 for this Bitubo kit.
And yes, the rear shock on the F800GS can be resprung. That's what you do with this kit:
