Default 03 CRF450 suspension settings

     

So I weigh 170 and I have set my race sag. My forks rebound and compression (as well as my rear shock) are all set on factory settings. What are some good settings to start with. I know MotorcrossAction mag test rides the bikes and gives suggestions but I can't find the old issues.

First off welcome to ATM.

Second, VERY nice choice in a bike.

Ok, here's my take. I think the rebound is a little fast on these bikes in stock form. I'd go out (counter clockwise) 2 clicks on both the front and back.

Before doing that though, I would count the clicks as you click it all the way in for both sides of the forks. then count them back out that number and then make sure they are the same. I wouldn't be surprised if you find both the rebound and compression clickers off at least 1 to 2 clicks from each other. So make them the same. Then go out another 2 clicks on the rebound. Then ride and see.

As for compression... you really have to decide for yourself if you think it's too hard or soft and go from there.

Another thing, Write all this down as you do it. You will want a record of what you had originally, so if you mess it up and hate it, you can go back to stock, and then readjust from there.

A rule of thumb is that rebound affects compression to a degree, so adjust rebound first and get it where you want it. Then adjust compression after you get it dialed in.

Also, never adjust more then one thing at a time. You will never know what you adjusted that helped or didn't help if you do. Adjust rebound only, then test ride and see, adjust some more if needed, test and see, then if you get it where you think you like it, then and only then move onto compression.

Another rule of thumb is that you count clicks from full hard or all the way in (clockwise). So if rebound is at 10, and you go out 2 clicks you are now at 12.

A very good tip that shocknut (our resident Suspension guru) turned me onto it setting a range. What I (and he) meant by this is to start adjusting compression (either soft or hard first) in 1-2 click increments (often times, I don't notice 1 click changes, which is why I usually go 2 until I get it close then I go 1 to fine tune it) going out (aka softer) then ride and see what you think, then go another 1-2 clicks and ride until you think it's too soft. Then write the number of clicks down as your Too Soft setting. No go back to the original setting and start going in 1-2 clicks ride and adjust some more until you get to a setting that is too hard/stiff, then write that number down as your Too Hard setting.

Now you have a range that you can work within, which is nice because once you get this clicker thing down, you may find yourself adjusting for different tracks or riding conditions so you can get the most out of your suspension. It is my opinion that one setting is not the best for all situations.

Also, I know you said you have adjusted your sag, but I wanted to put in my .02 cents on that too. I personally find my CRF likes 95mm of sag the best and turns best at that setting.

Hope that helps.

Oh, 1 other thing. when you go all the way in it will stop or get harder to turn. At that point your done. DO NOT force it any further. Go back to the last click and call that 1.

Woody,
If you think the rebound is too fast in stock form why would you speed it up even faster by going counterclockwise. Too slow the rebound down you need to go clockwise!

DOH!!! I'm guessing I was pretty tired about then...

Thanks for catching that. I did mean in. As Russ so kindly pointed out

is the rebound adjustment at the top of the forks (bars) or the bottom (tire)? --and what about the rear shock, wish clicker is rebound and which is compression. also, just for me, rebound is how fast the bike returns to normal position and compression is how hard or soft the suspension is? thanks

Yep, how fast or slow it compresses, is controlled by compression, and now fast it bounces back is controlled by rebound.

On the showa's the compression is on the top, and rebound on the bottom

On the rear, there is a small screw in the middle, that's low speed compression, on the outside is a nut, that's high speed compression and then down on the bottom on the right side of the bike (as if you were sitting on it) is the rebound.

low adjusts for slow hits like jumps. High adjusts for fast hits like g-outs (pot holes) and other stuff that happens really fast.

What would you recommend setting the high speed and the low speed?

You have to decide that.

I already gave what my thoughts on this bike are at the beginning of this thread.

You will now need to adjust clickers etc and ride and see what you think. I can't tell you what you will like. or how it's reacting right now.

So now you have a good excuse to go riding so you can adjust it.
