STEADY NOW: Steering Stabilizers and How They Work


MXEditor

They aren’t sexy…but behind the scenes steering stabilizers aid in handling and can help keep you out of trouble when putting the hammer down.

Let’s look at how and why steering stabilizers work and some available options for off-road machines. We spoke to industry experts as well as enduro, motocross and desert riders and racers to get a good idea of why they feel stabilizers can be a necessary bolt-on.

Who makes them?

Fastway, GPR, Scotts, RTT and W.E.R. are covered here, and are among the leading manufacturers. They all have pros and cons and vary in some way so it’s important to read up and make the right decision.

What do they do?

Simply put, steering stabilizers are hydraulic dampers for the front suspension. They help control stress loads that can overcome both the front fork and the rider’s ability to control the steering.

Think of it like this…if you’re riding and you hit a big, sharp edged rock or root…your handlebars want to turn very quickly to compensate, sometimes wresting the bars out of your hands...leading to a yard sale or worse. The steering stabilizer can make that situation manageable by dramatically slowing down the speed at which the bars deflect, thereby affording you time to react and not lose (as much) control.

Steering stabilizers can also effectively minimize the “head shake” effect we all dread at higher speeds and contribute to less wasted movement extending ride time before onset of fatigue.

When talking with Drew Smith at W.E.R. he put it this way; “The W.E.R. steering damper is a rotary hydraulic device, and the nature of a hydraulic damper is to resist very little when moved slowly and resist much more when a deflecting blow drives the wheel off line. Dampers reduce fatigue and are very helpful in rocky and route technical terrain.”

He continued; “When using a damper for off road, keep in mind that more is not always better. If the damper adjustment is too firm the bike will have a swimming feel…you’ll feel your hands are always busy on the bars and you’ll be wasting energy in technical terrain…and saving energy is what a damper should be doing for riders.”

What do they cost?

These units aren’t cheap, but also not out of reach when you look at the price of a full exhaust or a new helmet. This market is a competitive one, with all costing approximately $400 - $500. Do your homework because depending on your stabilizer, as you made need certain adaptors, mounting plates and/or clamps to make it all work on your specific machine.

Is installation simple?

Some units are installed under the center point of the handlebars. This presents issues on many off-road bikes as they are designed to accept such additional hardware, but each maker has devised a way for this to be a fairly straightforward by making kits to keep the installation as simple as possible.

For example, Scotts offers bolt-on mounting kits that include items like bar riser(s), link arm, handlebar clamp and frame bracket and even items like integral handguards that they claim reduces installation time to under an hour. They also offer under/over handlebar options as well.

Scotts commented that “Most installations are very easy and can be installed by the home mechanic with basic tools. We provide a detailed set of instructions with color pictures specific to the customer’s bike the damper is being installed on.”

They continued; “On most models of bike we offer fitment on top of the handle bars or SUB mounted underneath the handle bars which will normally raise the bars up 25mm in height. For many bikes that have bars that are solid mounted to the triple clamps we also offer a SUB mount that adds rubber mounting to the bars to help eliminate vibration and harshness on your hands or wrists. Since the off road industry is dominated by KTM currently we do sell more KTM units than anything else and slightly more rubber SUB mounts than anything else.”

Raising your bars can drastically alter your riding position and to address this, GPR has cleverly devised a very low profile damper that allows for only a very slight rise in location by moving the adjustment dial to the left side and creating a dial that was easy to use but as small as possible, coupled with the creation of a "hollow" vane. The hollow vane allows for the damper to be mounted almost flush to the top clamp.

Fastway has another take on this issue and offers both an underbar and overbar mounting kit…and this expands the mounting options drastically. The underbar kit provides some great protection for the stabilizer itself and because the Fastway units have “on the fly” adjustability and you’ll want it to be as easy to reach as possible. Fastway also offers KTM and Suzuki frame clamps which are two-piece which they claim “makes installation a breeze. No need to remove the front end of the bike – which is a challenge specifically on the KTM.”

To eliminate the raised bar issue completely, W.E.R. stays off the top triple clamp and attaches their damper to the lower triple clamp via the frame, and claims that it does “not interfere with handlebars, controls or time keeping equipment.” You can see the obvious advantages to this type of mounting system just by seeing the units installed and you barely notice the unit is there.

W.E.R. continued; “The installation of the W.E.R. damper is in most cases easy, with a frame bracket attached to the frame by pop rivets or a bolt going through the frame gusseting from one side to the other. The damper itself attaches to the fender bolt pattern via a plate between the fender and the lower triple clamp, our location is unique and is out of the rider’s way.”

How does the rider control the damping?

One important thing to keep in mind when examining these units is their “on the fly” adjustability, which is offered by all in one way or another. Many riders we spoke to actually “set it and forget it” when using these products.

But as we talked to more serious racers who ride on more varied terrain (such as enduro or desert) they liked the instant adjustment of the damper and consider it to be a feature they wouldn’t do without. We don’t believe that many novice riders would be able to correctly use this feature without practice in a racing environment.

This feature is usually done by a dial on the handlebar-mounted unit, like the Scotts product that provides “on the fly” adjustment - whereby the damping can be adjusted while riding with two knobs for adjusting high and low speed circuits.

Scotts had this to say about adjusting their unit; “Keep in mind that, much like your fork and shock, you will run different settings for different extremes of riding. Most riders will find a setting that works for the type of riding they do and not have to adjust the damper from there, but if you moto one weekend and hit the salt flats the next you will run the damper adjustments differently.”

This adjustment capability is also a feature offered on the GPR V4 dampers, with the V4 featuring an ultra low-profile dial on the damper itself. GPR states; “The knob assembly rotates 360 degrees left or right allowing you to go straight from the softest setting to the hardest setting, if need be. It will not unload, unscrew, or pop out, disabling your damper unit. The lower the number, the softer the setting. The higher the number the harder the setting.”

The Fastway units boast the most adjustability in this segment with two models for adjustability of the damping features. First up is the System 3 which offers three fully adjustable circuits: high speed, low speed, and return to center. Next up in the Fastway lineup is the System 5 which offers five independently adjustable circuits: high speeds, low speed, return to center, cornering damping and cornering angle.

Fastway had this to say about their two distinct stabilizers; “If you are the guy that is constantly playing with his suspension (clickers) and or making adjustments to your machine, we recommend the System 5. In addition, if you are doing a very wide variety of riding (like yourself) we also recommend the 5. The System 5 is sweet because you can go through a mile of sand whoops with your low speed cranked up and hit a 180 onto some tight single track and have the best of both worlds. The cornering angle allows you the ability of running a higher low speed setting while retaining the quicker steering ability of the low speed cranked all the way down. Then once you hit the next mile of sand whoops, you don't need to adjust your low speed back up.”

The RTT damper is different in the way you adjust it, it uses a remote valve on the handlebar and they claim “The seven position adjustment knob is coupled with a three level remote valve allowing for precise dampening...”

Last up is the W.E.R. unit, which offers adjustability on the unit itself. The damper is installed on the lower triple clamp and the adjustment knob is on the unit itself, therefore “on the fly” adjustments are not possible.

What do they weigh?

Damper weight and associated mounting hardware can range from approx. 2-4 lbs in total…and the higher up you carry this weight, the more detrimental it can be so this is always a concern.

Do they wear out?

Yes dampers can (and do) wear out and most companies mentioned here offer a low-cost mail-in rebuild service. Scotts says; “The damper itself can be a lifetime investment with simple maintenance and will follow you from bike to bike with just buying the new mount for your new bike.”

Should I get one?

In our experience and when talking to off road riders, it seems to depend more on where you ride than how you ride when deciding on a steering stabilizer.

We spoke to the folks at Scotts and they said; “The damper will apply itself for any type of riding you do and is adjustable so the same unit will work for the Baja rider doing fast, high speed riding to the woods rider doing tight, twisty riding.”

We then talked to the folks at Fastway who offered: “Desert riders enjoy added insurance with the highly adjustable high speed dampening capabilities. This will reduce headshake/shimmy and if you have a high-speed impact such as a root and rock, the assistance of the stabilizer can even prevent some types of crashes. In addition, the high-speed damping circuit reduces the force of impacts through the bars to help reduce rider fatigue and keep the vehicle going in a straight line.”

For Motocross; “Stabilizers reduce headshake and fatigue, allowing riders to loosen grip on handlebar allowing you to ride more with their legs. There is a noticeable difference in cornering and the stabilizer will help/assist in holding the line. And for Adventure bikes, they reduce fatigue by allowing riders to loosen their grip.

In regards to Enduro, Fastway offered: Corning angle controls give riders the option to run a high amount of low speed dampening without slowing down steering in the tight sections. This adjustment controls resistance level when the handlebars are turned into the “cornering” range as set by the sweep adjustment. Basically, cornering or sweep adjustment establishes the “range” of protection, left to right, that you want. When the damper “breaks to free” this Cornering Damping level adjusts “how much” it breaks away.”

We then spoke to both motocross and enduro riders who were in different camps. Talking to casual and serious motocross riders, the stabilizer seemed to be regarded as unnecessary on smooth MX tracks as the lack of sharp edged obstacles coupled with the additional price/weight tradeoff just wasn’t worth it. Some weren’t even aware that their motorcycle had one installed from the factory (like the Honda CRF250 and 450).

But when we spoke to enduro and even casual vet woods riders, they all seemed feel it was a helpful item and the cost and weight tradeoff was absolutely worth it. Many commented on the fatigue reduction aspect and felt they could ride longer and faster with the steering stabilizer, but many confessed to not utilizing the on the fly” adjustments after they began their riding day unless the terrain changed radically.

Desert riders and racers also swore by the units, calling it a “must have”, especially as the speeds increased. Most felt there was an appreciable reduction in high speed headshake as well as protection against unforeseen obstacles hit at lower speeds.

In Conclusion

Steering stabilizers offer lot of adjustability and light weight in a small package that can improve handling and your bike control at an affordable cost. If you ride motocross you may feel you might not need a steering stabilizer…but you probably could use one. If the factory is installing these units on the new bikes there is probably a good reason, and soon you may already have one installed when they build your new bike.

If you ride desert, enduro or woods these units are a no-brainer. Just one crash due to unforeseen obstacles can wreck you and your equipment causing major damage or even worse, depending on the speed. The adjustability and control offered is valuable and can be exploited to achieve higher speeds and less fatigue while featuring a built-in safety measure that can save you from machine damage and injury.

Nice tech article. :thumbsup:

Moto doc, there's also Motosportz, MSC and a few others but the OP did mention mainstream.

One thing not covered is some units damp to center and some don't. One should do some research on this before ordering a unit.

I regard these units as mandatory.

One might note the Scotts SUB stabilizer mount prevents the forks from sliding up the top triple clamp on KTMs, new Huskys and Betas. This might be the case with some others too so one should keep this in mind if they wish to lower their bike.

Although well-known for street bike stabilizers and great MX suspensions, during the course of researching this article I did not find one rider or racer who used the Ohlins unit. That's a primary reason for them not being examined in the article.

If you have experience using the Ohlins stabilizer, this would be a good place to post it!

Thanks - Sean

I agree return to center damping is important and I would have like to spent more time explaining this functionality. I may add this at a later date. Thanks for the props on the article.

Great overview! I just laugh every time i read "dampening"...especially if that's a direct quote from a damper manufacturer. It's not "getting things wet", it's providing velocity-dependent resistance to motion. :-)

 

I know, I know, we could say that the motion is being dampened (reduced), but I'm an engineer and find it more appropriate to apply the definition used in actual motion control, as the component we're referring to is a fluid damper. In most cases: controlling flow of a fluid by using a predefined or adjustable orifice.

 

I'll see myself out now...

My experience...

 

Fastway pin mounts break. 

 

GPRs leak too often... customer service is good about swapping or repairing units.

 

Scotts just work... good customer service is nice...  a product that doesn't fail is better !

I would never use one on an MX or Woods bike, but for a dual sport they are perfect. 

 

In talking to all kinds of riders I'd say woods/enduro and desert is where riders liked using them the most.

there only a band aid i was told i have an 87 kx 250 thats stable as a rock.

Sort of like having suspension is a band aid, or having a clutch?  You don't have one, probably have never used one (am I correct?) yet you feel qualified to dis them?

Having ridden a 1987 KX250 I can assure you it's not as stable as you think...if you ride it in woods, desert, etc. you may wanna try one of these units.

      My top end went on m 98 cr 125, the needle bearing clip came out and broke apart and shrapnel got everywhere and blew it up. I cleaned out the top end and washed out the crank with the bike upside down. the bike starts up great and seems to run fine but im getting a weird di-di-di-di-di-di-di noise coming from the motor. i tried adjust the power valve and tightening everything but the noise is still there. Here is a link to a video where you can hear the sound. It gets louder as rpm's get higher and at really low rpm barely idling it goes away. I am pretty new to bikes and 2 strokes so any help would be appreciated.

      I want to get a cheaper used FMF exhaust for my bike. The one on eBay I was looking at had some dents in it. Do dents in the muffler have a big impact on the performance? Also the pipe looks to be turned the wrong way does that rotate? I don't want to buy this if the pipe will not rotate because I think it looks like its turned the wrong way and wouldn't fit.

      Hey guys, 
      I am really needing some good advice here from anybody who has ever owned or rebuilt classic Yamaha 2 strokes (1989 - 1994). I live in South Africa, and bought a little farm thumper while on holiday this past weekend. It was advertised as a DT175 which is a bike that is easy to get parts for down here. It has been cosmetically customized and looks pretty darn cool... and lets face it, all the old classic Yamaha 2T engines look the same at a glance! So I genuinely thought it was a naked DT. The bike had no papers, and was used purely for the farmer to putt around on his farm.
      The only things needing attention was the stator cover which had snapped in half - this was visibly noticeable, and a little leak from a badly resealed gasket (both generally easy and cheap to fix here). The bike was still running and idling fine, started first kick, and I had a little ride around the farm before loading the bike up onto my pickup and heading off, thinking I could fix this thing up nicely in no time for next to nothing, and have what we call down in SA "a nuwe speelgoed" (A new plaything) for the weekends when I am not riding my beloved and reliable DRZ400SM. 
      SO, I get home and decide to contact our local Yamaha branch, out of interest, to find out the history of the bike before I start fiddling (Don't ask me why I did not do this all before I bought the bike - It was a spur of the moment purchase, and was sold to me for dirt cheap!). I send off the VIN and engine number. Comes back, and this little freakin' turd turns out to be a 1989 TDR180!! WHAT. But now I am stuck as we do not really have TDR's down here - and I have never even seen one myself.
      Long story short - What alternative could I use as a stator cover? Do any other old Yamaha 2T model stator covers fit the TDR or share similar engine parts? Ordering from Ebay is so expensive thanks to my country being in junk status due to a junk president. So the shipping costs more than the actual item does, and our customs is a joke too. Yamaha has also advised me that this stator cover has been discontinued.
      I have put up local ads looking for parts, contacted FB 2T groups, and local shops. Nothing for TDR's has come back yet.
      Any advice or sharing of experience is welcome!
