there is practically no suspension settings available from light weight riders( presumably because there are hardly any lightweight riders), mostly suspension advice given from heavier riders so thought i would be that light weight guy to give you my first hand experience. i weigh 60kgs and my kdx220 has wanted to jar the fillings out of my teeth since the day i bought it. recently did a complete suspension overhaul and these are my settings
front forks-
0.32kg springs with 10mm preload
2.5 weight oil in one leg and a 50/50 mix of 2.5w/5w in the other leg
110mm oil height
compression 17 clicks out
5 compression shims removed and pay particular attention to the shim basket position as put on incorrectly this is like adding 10 shims (as per photo)
rear shock-
yz125 rear spring(4.6kg)
120mm preload
2.5w oil
140 psi nitrogen charge
compression and rebound shims removed (as per photo)
rebound 10 clicks out
compression 15 clicks out
results- it handles so well i can't stop riding it. it feels super plush and i have no issues with bottoming although most of what i do is technical single track, tree roots and rocks are a pleasure to ride over. i haven't taken any sag figures yet so there still might be some room for improvement but i can't imagine how it could work any better. now i can actually focus on developing riding skills rather than just holding on tight

I'm a lightweight rider myself at about 138-140lbs (63-64kgs). Thanks for sharing!

Re: suspension settings for ultra lightweight riders
Good info. The only thing I would caution is using different weight oils in each leg. That can theoretically lead to one leg compressing or extending at a different rate than the other which could affect handling and stress the rim/axle/bearings. Not a giant risk, but it is a possibility. Glad to hear it's working well for you!
