The previous owner of my bike was about 50 pounds lighter than me what kind of adjustments should I do to my suspension (and how do I do it) to better handle my weight (210lbs).

 

210? I wish...Just max it all our and have fun. Its adjustable.

 

Best would be to replace the springs in the fork and the one on the rear shock to match your weight.

 

Both these threads cover the SF model, as the D-Tracker is the same in Asia as the SF is in the US.

I am 230lbs & had to really beef up the front & rear suspension to cope with hard fast road riding.

Much reading to do!! It makes so much difference on the bike & so worth it.

 

Not sure if i wanna dissasemble my suspension. It rides fine. When i sit on the bike it barely even goes down maybe its already good for my weight? If not is there adjustments i can play with like the little screw on the preload adjuster for the rear shock, and what about those 2 large round adjustable things that sit on top of the rear spring what can i do with those?

This is what preload is and what you need to do with it. You "might" have the correct sag for your weight and bike, but the odds are that some fine tuning of the shock spring collars is required. You also have compression and rebound adjusters to tweak, and this article has instructions on how they work. Doesn't matter if it's an SF or S model...same principle.

 

best $40 i spent was a professional front and rear suspension adjustment for my weight...one of my first posts on here was about how my klx250sf would speed wobble at higher freeway speeds and nearly go into a tank slapper...too much bouncing and getting on/off to do it yourself...go to a shop that specializes in suspension and get it set up perfectly for your weight..it makes a huge difference to the ride through bumps and high speed stability...

 

Those are the preload adjuster. The upper one is the lock, the lower one does the adjusting. The "screws" are for compression and rebound. The owner's manual covers this.

Better yet: do what ahnh666 suggested, let a pro do it.

 

A friend of mine is 170lbs & thought the suspension was a little spongy on his SF.

If your bike is completely stock & not adjusted, then the bike is simply dangerous driven at any speed. Fast braking into corners or emergency braking with those springy soft forks just is not acceptable! $100 for firmer springs (0.48) for your weight & 4 or 5 extra clicks should be perfect up front.
I'm 230lbs & John @ Moto-pro gave me 0.52 springs!! Don't look at the numbers on the "S" model that members throw around on here, the forks are different (S fork springs are longer & have more travel etc).

Wind the preload rings down about an inch on the rear spring & 3 extra clicks of compression & 5 extra clicks of rebound & the rear should be acceptable for your weight. Those numbers may not be perfect but it's a start. That's free.

You won't believe what a difference it makes! I have recently riden 2 stock SF bikes & they are absolutely crap ....NO comparison!

Or take to a suspension specialist & let them work their magic
