motopower videos

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.


Hope it helps.

      Hey guys, I'm wondering what suspension settings you all are running front and rear?  I have a 2017 crf 250r I'm a 210lb newer rider, my settings are currently set at,
      rear suspension low speed  at 12 clicks
      rear suspension high speed 2 turns
       rebound is 12 clicks.
      Left front fork inner chamber 150psi, outer  chamber 10psi, balance pressure 150psi
      Right front fork compression position 7 clicks, rebound 29 clicks
      Sag is 4"
      Thanks guys

      One of the most common calls we get here at the shop is “how do you recommend I go about tuning my suspension?” Good question! The second most common call is “I started turning clickers on the front/back/bottom/top etc. and now I don’t know what I did, help!” The amount of improvement you can gain from proper suspension setup is significant, if you go about it in the right way.
      Look at it this way: if you are 6ft. tall and get in your truck after your 5 ft. 3in. wife just drove it, the first thing you are going to do is adjust the seat/steering wheel, etc. for your size. The same thing goes for your bike’s suspension-last week we had (3) 2010 bikes in the shop for revalves at the same time. Identical models, one guy was a 150lbs. pro racing MX, the next guy was a “B” level GNCC racer and weighed 220, and the third guy was a 180lbs. trail rider. Same bike, three totally different setups!
      So with that in mind, here is where to start:
      • Grab your owners manual, a computer, clipboard and a scale. You cannot effectively start tuning until you determine if the correct springs (fork and shock) are on the bike for your weight. Put down the double cheeseburger, hop on the scale, and get your weight in street clothes. Add in for your gear, which typically runs between 20-30lbs. You can easily check recommended spring rates by visiting under their spring rate calculator. Look in your manual (or ask your tuner) and see what rates are on the bike.
      • If you need to change spring rates-do it first. Trust me on this, trying to tune suspension with the wrong rates is not only frustrating, but you will be short changing yourself on the results. On most bikes the shock spring is easily changed, fork springs can be a bit more difficult-get qualified help if you need it.
      • Even if you are familiar with what “clickers” are, take a moment and read your manual. Determine what style of forks you have (closed cartridge or open cartridge), where the compression and rebound clickers are, and check to see if your shock has both a high speed and low speed compression adjustment.
      • Grab the right tools to adjust, load up and go find a typical piece of terrain to test on. By typical I mean your MX track, hare scrambles course or favorite singletrack. You don’t need to ride a 30 mile loop in order to adjust your bike, rather focus on finding a section of track/trail that has all the different types of jumps/bumps/whoops you encounter.
      • OK here is where I will preach a bit-everybody has a buddy or two that claims to “know suspension” and setup. This is YOUR bike, and unless you plan on dragging him around on the back of the seat the end result of your tuning should be focused on what feels good to YOU. Trust the feedback the bike gives you…..
      • SET YOUR RIDER SAG!!!!!!! This is critical to tuning properly. Again, look in your manual or ask your tuning dude.
      • If you do not have an idea of where to set your clickers, put them in the middle of their adjustment range. This is your baseline setting.
      • Gear up and get warmed up. It is important to be loosened up on the bike BEFORE you start tuning, or you run the chance of mis-diagnosing how the bike is feeling (I never start testing until I have at least 15-20 minutes of warmup time on the bike-I always ride stiff initially and sometimes do not get into a groove until then). Some guys can just jump on and pin the damn thing right from the truck. You know who you are, Wattsy……
      • Remember, this is a tuning session not the MXoN. Use you head and ride at a pace UNDER you max speed-there will be plenty of time to “fang it” once you have zeroed in on some good settings.
      • OK-ride and get a good feel for the bike with the clickers in the middle of their range. Now it’s time to really find out what “too soft” and “too hard” means.
      • Take your clickers and turn them all the way out, full soft. Go ride the bike, but take it easy-it will feel ALOT different. Then come back in and turn everything all the way stiff-go ride again, being careful as this will feel totally different again. For guys that have tuned a bit, these two steps might seem pretty basic, but you will be amazed at the difference in how the bike feels. This is especially helpful for guys who are just starting out.
      • Set everything back to baseline. FROM THIS POINT ON YOU WILL ONLY MAKE ONE ADJUSTMENT AT A TIME!!!!!!
      • So now you will want to determine your tuning range. The tuning range is what settings you will use to adjust for different conditions. For example, If you are an MX racer as well as an occasional singletrack rider you will want to use different settings for those conditions.
      • Fork compression is a good place to start. Ride your test section at baseline, then go about 3 clicks softer. The question to ask yourself after each adjustment is: Does it feel BETTER, WORSE, or THE SAME????
      • There are no right and wrong answers, only what you feel. So let's assume that the 3 clicks softer felt better-go 3 more clicks softer each time until it does not feel as good. You have just found the soft end of your fork compression tuning range. Now return to baseline and do the same thing, only this time go stiffer. After you have found the best compression setting, work on rebound. Remember, one adjustment at a time ONLY or you can become confused!!! Do the same testing with your shock. Once you have both comp and rebound individually adjusted, you can fine tune them to work together-just make one adjustment at a time!
      • As a final test, when you have what you would consider your best setup, write it down, then go back and compare that to your initial baseline, riding both setups back to back. Might surprise you…….
      I could go into some advanced tuning topics about the interrelation of compression/rebound, high and low speed comp, tuning for extremes, etc. but we will save that for another newsletter. Take your time, tune by how your bike feels to you and have fun. You will be surprised by how much better you will ride with well adjusted suspension.

      Selling the showa A kit off of my yz250. It comes with a set of like new x trig adjustable triple clamps. Have 4 rides on rebuild and overall in great shape. Few dings, no dents or leaks. Setup for a 165lb a rider. Work absolutely awesome! I got hurt and cant ride for a year so I'm selling off some of my parts.

      lookin to upgrade my suspension on my 06 cr250, curious whats possible with some work.
    • By tplayer100
      Currently have a 2000 drz400s work stock suspension. From my understanding this is the worst suspension the drz ever came with without even rebound damping adjustment. Therefore I'm looking for a upgrade. I'm seeing three approaches to take. First being a newer year s model suspension with dampening adjustment. A SM model USD forks and triple tree or some USD forks and triple tree from a rmz. So if you were going to upgrade what direction would you go. I currently ride off-road mostly but I do have some 17s for on road with as well so have to keep that in mind. Thanks
