The latest CRF fork springs are listed in the manual as .46kg/mm but are testing at .49. This is true for all the ones I've seen so far. Have your tuner leave the fork springs and replace the shock spring only. The CRFs are better on the midvalve this year but far from perfect. Make sure this is adjusted as well as the rebound problems. Once the compression circuit is balanced to your requirements you will have good performance. I would recommend avoiding the aftermarket lock ring. These items are a waste of time and will be matched in any benefit with heavier oil in the outer chamber. Once you have everything adjusted correctly you probably will have no need for the subtanks. This is a very capable fork on what is a very capable machine. All you need is a capable tuner.

This is the first time that I've heard that the fork springs have tested heavier than .46. Is this common knowledge, or a new discovery? Is this published or noted anywhere else, or is it your own observation?

Thanks for making this known.

hmmm I'd be surprised if they are checking out at .49.

I have ridden his bike a few times and the forks are pretty dang far down in their stroke with me on it(210lbs) I have .49's in my 02 and they hold the front end up MUCH higher.

I am about to help my brother with his 05 setup. He weighs 220 and likes my suspension. I hope we don't get .49 springs for him to find out that it doesn't help!

All of the '05 crf 450 springs I have tested have been in the 47 range. However, I just tested a set I took out of a bike last week and one tested 47 and the other at 49. These were the '05 springs with the two ( 2 ) cut (grind) markings side by side. If you are getting your suspension done --- make sure to test.

      Hi,
      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!
      Thanks!

      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.
