WR250R Scotts Damper Install Empty

I just installed a Scotts on my WR and I thought I would take a few pictures and document things.
I ordered my Scotts kit form Renazco Racing and I already have this damper on my F800GS. I really like the quality of this damper as well as its adjustability. It makes a big difference in sand, rocks, and overall fatigue reduction.

Start off by putting the bike up on a stand and then blocking the front wheel. This will make things easier when you loosen up the triple.

Next up you need to remove the upper bar clamps. I am using the Highway Dirt Bike guards so here I am removing the top plate. I ended up with a new top plate that would allow me to reposition my Powerlet outlet back behind the damper.

Then remove the fork clamp pinch bolts.

WR250R Scotts Damper Install P1010003-L

Lift the bars out of the way and loosen up the main triple clamp nut. This requires a 27 mm socket and a fair bit of force.

WR250R Scotts Damper Install P1010004-L

At this point you need to remove the lower bar perches. My Highway Dirt Bike perches have an allen bolt that passes down through the top with a nut on the bottom. I found it easier to grasp by sliding the upper triple free from the forks. I believe the OEM perches have a bolt that comes up form the bottom. In this case you may want to leave the triple at least partly on the forks so you can have something to turn against if the perches start to spin.

You can now install the Scotts lower SUB mount. This is attached to the triple by the Scotts bolts that pass up through the bottom of the triple into the SUB mount. It is important to make sure you use the included aluminum spacers shown below (yellow zip tie is pointing them out), or the damper wont clear the top of the triple. Note that this picture was taken later in my install but it shows the position of the spacers. The bolts have lock washers and I recommend also using lock tight.

With everything out of the way you will be looking at the castle nuts.

WR250R Scotts Damper Install P1010006-L

Remove the lock tab, jam castle nut , and rubber washer. These items will not go back on. I didn't have the special socket for the castle nut. The Scotts instructions suggest using a screwdriver in the notches to loosen / tighten these nuts. I just carefully used some channel locks.

WR250R Scotts Damper Install P1010008-L

Remove the lower castle nut just over the head bearings.

WR250R Scotts Damper Install P1010009-L

Replace this with the special nut that Scotts supplies. This is a 32mm square nut. The recommendation from Yamaha is 38 Nm, loosen fully, then retighten to 7 Nm. I couldn't figure out a way to measure this exact torque so there is some feel involved. You want the head bearings secure but not so tight they impede motion of the bars side to side.

WR250R Scotts Damper Install P1010010-L

Remove the front gas tank bolt.

WR250R Scotts Damper Install P1010011-L

Set the Scotts frame bracket over the stem then lift up slightly on the gas tank to allow you to slip the front edge of the frame bracket into position.

WR250R Scotts Damper Install P1010012-L

Make sure the frame bracket is fully seated in position over the stem and under the tank edge.

WR250R Scotts Damper Install P1010013-L

Replace the front gas tank bolt (10 Nm) and then put the stock castle nut back over the Scotts frame bracket. According to Scotts, this should be snug then 1/8 turn more. If you over tighten this you will add tension to the bearings. Again I used channel locks.

WR250R Scotts Damper Install P1010014-L

Slip the top triple back into position and secure it with the main nut. 27mm tightened to 120 Nm. I straddled the front wheel to keep it from rotating off the blocks when I torqued this down.

WR250R Scotts Damper Install P1010015-L

Fork pinch bolts back in position. 10mm tightened to 23 Nm.

WR250R Scotts Damper Install P1010016-L

You can set the bars back into position and now is a good time to check all the cables. The Scotts will raise up your bars a bit and you need to make sure you have room when the bars are turned fully side to side. I had to re-route my ignition / starter button mount and cable.

Grease the floating tower pin and slip it into position. This pin has a collar that can be adjusted to get the best height. You will see this better with the damper down on the SUB mount.

WR250R Scotts Damper Install P1010018-L

Align everything and place the damper down on the SUB mount. Make sure that the tower pin doesn't hit the bottom of the damper. Secure the damper to the SUB mount with the supplied bolts.

WR250R Scotts Damper Install P1010019-L

Check your clearances. The tower pin should be roughly in the middle of its range.

WR250R Scotts Damper Install P1010023-L

This shows why you need the spacers under the SUB mount so the bottom of the damper doesn't hit the top of the stem.

WR250R Scotts Damper Install P1010022-L

Bolt your bars / top plate back on and you are good to go.

Hopefully someone will find this useful.

Did you check the bearing in the frame bracket before installing ? Mine was FUBAR'd, needed to get a new from Scott's and install it myself.

Really appreciate how clear you made it. Now could you do one for greasing the steering head bearing? Dang, too late. Thanks for sharing, really helpful.

NICE write up!!! Just a quick question though for all of you in the know;

What exactly does the damper do? And how does it help??? Can you (do you have to) adjust it on the fly for rocks and sand?

Chrispy
Yeah I checked that bearing after seeing one of your previous posts. Mine was in good shape.

Yaw
I thought about pulling out those bearings while I was there but they only have about 2700 on them and they still feel OK. Next time I pull apart the front. Very happy

The damper has a large potential range of adjustments that include at what point the damping begins, to slow speed damping, to built in high speed damping (think protection from tank slappers). The damper has two main control knobs you can see on the top. The right one is the main control and you can easily dial it up or down on the fly as conditions change. I never really mess with the left control, as it is the high speed valve and on the WR this is less important than the base valve control on the right. As you increase the base valve control this translates into more "stiffness" or resistance you can feel when you turn the bars. This can be helpful or a nuisance depending on the circumstances. I put a Scott's on my F800 to help manage the bike when it is fully loaded in rocky terrain ( think baby heads ). After I had it on the bike, I realized what a difference it can make in other situations where the bars can get pulled around or abruptly deviated. It also helps a lot on long days with overall fatigue as I find I fight the bars less. In sand I tend to crank it up higher and let the damper do its thing rather than applying the death grip to the bars. Same in deep gravel. Take that for what it's worth as I freely admit I'm better in rocky stuff and no great sand rider. The damper also has some small controls on the side that will let you set at what degree the damping effect begins. This can range from 34 degrees to 90 degrees (full). The stock off road setting is 44 degrees and I have never felt the need to change mine yet. Scotts also makes two variations of the damper with a road version which damps in both as the bars turn away from center and back to center, and an off road version which damps only as the bars turn away from center. In my discussions with the guys at Scotts, I was told this allows you to quickly pull the bars back to neutral without fighting the damper as it is expected you are making more frequent and rapid adjustments off road than on road. The WR damper comes stock in the off road configuration. Overall, I find this a really nice addition and extremely helpful in certain situations. I like this thing enough that I am likely going to break down and get a third one for my Hypermotard. I guess then I can evaluate the whole on road vs off road configuration thing better. The above info is to the best of my admittedly limited knowledge so if anyone can correct me, please feel free to do so.

Wow, thanks Ronin! That was definitely a helpful answer. It seems like a pretty advanced little unit. I may spring for one of those some day.

Super write up.
I installed mine about three weeks ago and you are as accurate as it can be.
Thank you for a perfect write up.

I was just reading your ad about a Scott steering damper install the ad reading is fine but there are no pictures or I cannot open them it looks like you actually tried to send them in the post is there any way you could reply to me and make sure the pictures are seen?
