Spoiled by yamaha

So i WAS. Yami guy for years, im a Vet B rider on a good day, 175 lbs. although i had my old bikes done by ENZO it didnt feel as an emergency becuase my YZFs had great stock feeling.

My New 2013 KTM 350 sxf is a great overall bike, but these forks are HARSH. , i cannot send them out til after summer so i need to soften that intitial hit in the front. Its unbelievably different than the Yami in that respect.........

Suggestions besides just softening compression on clickers please..


Any post any how to video links on what i can do

do you only use it for mx? if so you will need to drop a couple of spring rates mainly on the front but do you have a race/static sag numbers for the rear?

Edited by yamaha837

The springs fit perfectly for a 80 kg/ 175 lbs MX Rider. If you ride woods you may drop a rate, but this wont solve your problem.

I just have the 450 and 250 stacks for the 13 KTMs but I think the 350 wont be much different.

Actually I copied these stacks with a smaller base clamp for a SXF 350 11 and the rider is quite happy.

More input data are needed for proper advise.

Type of riding, where do you notice the harshness, terrain and so on...

Pull 10mm of fork oil out per side....

Sorry to hear your 350 fork is giving you trouble.

A real solution is going to require internal modifications; valving changes at a minimum. Changes like springs and oil level can make the fork softer but won't really change the overall ride character. If you are able to do the work yourself, you might try Vietze's suggestion as an intermediate fix.

The us 350 seems very harsh and the euro one much less harsh so I wonder if the stacks are very different

What is harsh about them? Mistroke? I found that the 350 was mainly harsh on choppy stuff. Id play with the rebound try to speed it up and also try going stiffer on compression to bring it higher in the stroke. Some people are taking out 20cc of oil and that helps.

A little off topic but I have been worried about going to a Ktm 300 (open chamber) from yamaha's suspension, even my 11' Yz 450 was a pleasure to ride in the technical endure stuff, just too heavy but a pleasure to ride,

I still wonder if I can get the susp on a 12' 300 xc-w close to the yamaha's

The WP OC forks are pretty good for woods.

However the EXCs have a bit of a stiff basevalve for tight, technical trial-like woods riding.

For some reason i didnt realize you were talking about wp oc. All of the 530/525s that i have ridden all were oc and thats my only experience. But it has always been better than wp tc forks offroad. I wouldnt worry because ktm has been winning hard enduro for years and thats something they def k ow what their doing

This thread is about the TC fork in the 350 sxf but stu asked something about the OC fork. So I responded to that.

Do you really think KTM won that much offroad events because they know how to set up OC forks?!

A properly tuned CC fork is also nice for woods riding. Its not the concept, its the setup which makes the fork good.

If you never liked a CC fork for offroad riding, the setup just wasnt altered for you.

Ive had both and oc forks "seem" to be more plush on rocks and roots. Now i assume thats because tc forks have to have the inner chamber pressurized. That doesnt mean a tc cant be as good i was refering stock for stock.

According to KTM, they are totally different stacks, springs and oil height.

Yea, the stock CC WP forks do need a bit of work. Oil height is by far the first thing, they do tend to have too much oil in them. Removing oil will change the compressed air volume a tiny bit and that generally is the quickest/easiest way to reduce harshness. A good way to define oil level is to throw a zip tie on the bottom fork tube and see how much travel you're using. Then you can slowly reduce oil level 10cc's at a time, until fully bottoming equates to 10mm of exposed chrome above the axel clamps.

I've run the CC WP forks down to 340cc's (stock is 380 or 390 depending on the year).

So start experimenting with oil height, 10cc's at a time and I bet you'll feel a huge difference.

      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 www.racetech.com 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
