Can anyone give me some advice on what would be a good suspension setting starting point for me on my 848 Evo in terms of sag, rebound and compression? The setup out of the box on the 848 is notoriously bad I'm told but works well when dialled in. I have yet to be on track with the bike so I'm in the dark and want to have an at least half decent setup before I do so. I'm 90kg. Any advice is much appreciated!
I was the same weight and had mine set up but with the standard spring they couldn't get any more than 5mm of sag, the dealer wound the preload off as much ass he could but couldn't get it to sit. they recommended a new spring, and also while i was there an adjustable ride height rod so that you can dial in the sag etc then set the ride height properly to get the bike to turn. Sorry, not much help other than to say if it's a standard spring, I would recommend getting MCT or Maxton etc to re-spring it for you.
Just just had mine revalued front and rear at Reactive in York and although I haven't used it in anger yet I can tell it is a big improvement. Point being I don't think you can adjust the problems away, especially at the rear end
RT - Digital Product Search to know the right spring weight (front will need changing to get right IME at your weight, rear probably about ok, may even be too firm!) nice 'how to' to get base settings like sag (which will also tell you if springs need changing if you cant) Motorcycle Suspension Setup
By far the most important thing is geometry. Get a rear ride height adjuster for it. Suspension is secondary IMO and has less of an impact, but it definitely helps. I noticed improved feel from the rear (fnar) after I got a good baseline setup, then fine tuned it from there. But dialling in the trail with ride height was a transformation. It really depends how you ride and want the front end to feel so there's no real golden setting for everyone. I like quite a lot of front rebound damping. You might hate it.
