First supercross race, suspension suggestions

Recommended Posts

Hey all, I've decided to buck up and throw in an entry for what is probably the only Supercross race that we get a year

I have had softer springs put in and the suspension is mostly tuned for rough tracks like we get in Ireland.

I would like to know some tips for fine tuning the suspension for supercross, like is it to be stiffer? what about whoops? etc.

Thankin you :busted:

Bike is an 08 crf 250

Supercross set up is much stiffer compared to mx set up that you normally use.

At least one step stiffer springs to both ends, fork oil volume to max and much stiffer valving.

How much do you weight and what level are you?

If the valving is stock you have just about the best bike stock wise for supercross. Maybe put your stock springs back in and run about 400cc oil level.

This might do it since it's only one race a year or you could get it revalved if money isn't an issue.

you need to see what the track is like, and find out where you want to get the best time in a particular section. you can run stiffer fork springs/shock springs, but the valving needs to be appropriate as well. i'm not familiar with the supercross tracks you've got in ireland, and how they compare to the u.s. tracks.

You have to make the rear shock shorter, stiffer springs in front and rear, modified MV- less float.... stiffer compression and rebound.

alot of top ama pros run less travel in sx, look at the bikes on the stands, the wheels are really high off the ground.

because of the whoops?

the whoops sections are nasty. we did a tune for a rider, and the goal was to keep the swingarm straight (longest point), and with the least oscillation we could have without the bike packing up. the springs were much stiffer. when they fly through those things, they want to stay on top; skim the suckers!

not sure ? think it maybe to help with cornering as they are so stiff ?

for first time the most important is zero float on mid -or 0.10 and change the shim whit 0.15

or at least double the shim on mid!! add more preload on spring on crf i have try for a rider +7mm then stock

i put in another 7 shim on base .

the fork work good whit 0.47 spring the bike is not extreme
