suspension setup

[billy big rig]

Hi all,

I reciently bought a 2003 drz 400, and am hoping someone will have some advice on which rear shock spring would be best for me. I am about 225 and the stock spring is definately not enough for my size, what do you advise, and do I need to adjust the front shocks?

Thanks

i'm about the same size and from what i've found you should get a 6.0 rear spring and .50 front springs. there are quite a few posts on the subject if you search around.

Read the FAQ. Search this forum and the "suspension" forum. All this has been covered before, in detail.

Im at 245 and just got a 6.0 spring from race Teach. Best thing I've bought for my bike so far. Didnt feel like my bike was lowered with raked forks anymore.

Here's a link to Race Tech's spring rate calculator:

Thanks

The pre-load should be adjusted to set your sag. Search on "static sag" and/or "race sag".

[djsather]

yes, make sure to adjust the race sag correctly, if you have the right spring the static sag should be in the correct range once the static sag is set. most people go with a race sag of 90-100mm, but i would do some searching and see what you think is best for your riding style.

I finally got my drz out on the trails for the first time, and for that matter my first time on the trails. I have done lots of mountain biking but this is so much more fun, a buddy came with me to teach me the ropes. The bike handled amazing I've got the sag at about 90 mm and that seems to be perfect, I have to adjust the shock dampening but otherwise the spring is perfect.

Thanks for everyone's advice.
