baseline measurement for 03 CRF 450

Recommended Posts

I am looking for some baseline numbers, as for clicks out, for my 03 450. I am 195-200 depending on the day. I ride Vet intermediate MX. Suspension is stock. Once I get an idea of the base line numbers it will make it easier to tune. It handles everything good except I feel the the front end drops in the whoops. After market work is out of my financial reach for now, so any help would be appreciated.

At your wieght you really need stiffer fork springs. .49's would do wonders for ya. You can get them for about 90 bucks. So its not going to break ya...

At that point, with an oil level at 380cc, Id start the compression clickers at 7 and the rebound at 10 on the fork. The rear I run mine at 5 low, high at 1.625 out and the rebound at 10 or 11 depending on where im at. Also, Im your same wieght and run the stock spring in the rear.

Good luck.

If your not going to do the springs, you should probably run the clickers at 4-5 on the compression, but its going to be kinda nasty...You could add some oil to the outer chamber (15-20cc's) and possibly get away with 6 on the clicker. But it'll be kinda harsh in the smaller stuff... :)

Also, if the front end is dropping inbetween the whoops, back out on the fork rebound. Thsis will let the forks extend quicker and let them "reach out" for the peak of the next whoop preventing the front end from dropping inbetween them.

There is a fine line to dance, because if we run the rebound too fast, the bike will have a tendency to wash out in the flat turns and walk out of the rutted turns.

Take Care, John

Springs will have to wait for now. My suspension rarely bottoms though even when i come up short on my 65' step up it is not that harsh. I'll speed up the rebound 1 click at a time and see how it runs.

      I have a 2003 DRZ (actually a KLX400) and the head tube bearings are shot.  I ordered a new set to install but I'm wondering if anyone has any recommendations on other parts I should replace while I have the front disassembled.  I was thinking about new rubber fork protectors, but are there other things that wear out on the DRZ front ends that you can only get to when disassambled?
      I also broke off a replacement key that I got for the steering lock.  I must have been made of cheap pot-metal.  Should I just remove the whole lock mechanism?
      Any tips or tricks for getting the old bearings out and the new ones in would be welcome!

      Hey guys. I recently purchased a 16 yz250x and the first 2 rides i LOVED the suspension. Then the day before a race i reset all my clickers to stock and everything felt like crap. No plushness at all and deflected off everything. I now have a 5.4 shock spring for my 190 pound weight and dialed in sag. Any recommendations on where i should go from here? Right now the fork is 12 out on comp and 15 out on rebound. Shock is 1.75 turns out on hsc, 14 out on lsc, and 18 out on rebound. Any help would be appreciated!

      Today we’re going to be talking a little bit about automotive suspensions and how they work to smoothen the ride of your car. There are mainly three purposes of the automotive suspension system. First, they support the  weight of the vehicle. Second, they maintain accurate tire contact with the ground. And third, they absorb any shock that you get through the road when you hit a bump.
      Most modern vehicles come with an independent front suspension. Which means if one wheel hits a bump it does not disturb the other wheel. Nowadays, people use Coil Spring to support the majority of weight in the car. As it has a really good characteristics for absorbing any bumps as you go up and down on the road.
      However Springs aren’t very good at dissipating that energy. In fact that’s why you have the shock absorber. Which is there to smoothen out the ride and make sure the tire maintains contact with the road.
      In modern passenger vehicles the two most popular suspensions are McPherson strut and double wishbone style of suspension. The main advantage of the McPherson strut suspension is that it’s really cheap and simple that’s why a lot of manufacturers are moving towards this design. The double wishbone design allows the wheel to stay perpendicular to the body as it navigates a corner or as it goes over a bump. And that maintains good tire contact patch no matter where the wheel is situated. Another advantage of this design is that it can be made adjustable where you can control the position of upper control arms ball Joints.
