Planning to start some suspension work on the following bikes:

KTM 200xcw 2006

KTM 200sx 2003

Honda CR250 2005

Yamaha WR250 2003

I have watched a motopower video of the WR suspension being done. Are the KTM forks similiar enough to the WR to use for both fork and shock dissassembly? Or are they vastly different?

I am hoping the KTM forks are similiar to the WR forks. Hoping the WR shock is similiar to the CR shock. Was planning on just buying the dvd's for the cr (twin chamber forks) and the KTM rear shock.

Any suggestions or recommendations?

I would bet that there would be a good deal of difference. As you probably know, the KTM's are open chamber forks. The Honda and Yamaha are cc forks.

The motopower video of the KTM forks is a really good DVD. If you don't want to buy the dvd, go over to KTM Talk and look in the suspension forum. In the pinned section is a thread that contains detailed photos of the KTM fork assembly. Here is the link

The KTM forks are not difficult, at least they weren't for me.

A few things you might want to pay close attention to during the process:

Make sure your compression and rebound adjusters are backed out all the way.

When assembling the forks, make sure the spring guide is fully screwed down to the cartridge tube in place and snug. If not, your rebound adjustment will not work properly.

To disassemble correctly, you will need a thin 22mm open end wrench to hold the spring guide on the cartridge tube. After unscrewing the top cap, you will need

to pull down on the spring and insert the thin wrench on the spring guide. You might be able to find one, but most people buy one and grind it down. I got lucky and found one in an old tool box a friend gave me.

When you remove the fork caps, be very careful with the rebound adjuster tubes. They tend to stick to the plastic adjuster parts (located in the cap) and if not careful, the plastic tip can break. Then you are screwed! Just be careful removing the caps and you will be fine.

If it has been a while since the fork have been serviced, the tiny rebound spring that offers resistance to the brass rebound fitting, can stick in the cartridge tube and not come out. You have to work to get it out. It is not hard, just something to look out for. A thin clothes hanger can be inserted in the bottom hole of the rebound tube (where the rebound valve is located) and you can force the spring out.

When finished with service and adding fork oil, you will want to fill the fork with oil, pump them several times to bleed the air and them remove the proper amount

of oil (by using a syringe or oil removal tool). You remove enough oil to create an "air chamber" anywhere from 110mm to 140mm. Some people start with 140mm and then if the oil level is too low, you can slowly add oil through the air release screws on the fork caps using a syringe.

You can find a really good, step-by-step article here.

Another good article with photos is here

That is about all I can think of right now.

Hope this information helps!!!

Good luck.

I wasnt too worried on the front forks as the WR450 video I watched was open chamber KYB, figured they would be similiar, but thanks for the tips.

      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.
