WHO ARE WE?

Our Idaho-based staff consists of a former Suzuki factory racer, an ISDE silver medallist, National Qualifier gold medalists, National Hare and Hound competitors, and demanding weekend trail riders. With over 30 years of racing and trail riding experience, we know what "does" and "doesn't" work.  10 years ago we started with the Suzuki DR350 and DR350S and have gone on from there using what we learned from that experience to better the later model bikes. 

WHAT ARE WE OFFERING THE OFF-ROAD RIDER?

In the beginning we were trying to solve the DR350's suspension problems. We played with many different shim stacks, shock oils, and spring rates, but nothing gave us the results we were looking for. We wanted plush on the small bumps, firm up on the moguls, and most of all we wanted to minimize that dreaded sideways kick which was caused by violent bottoming of the rear when traveling at excessive speeds of over 25mph offroad.

In stock form, and the sag being set at 3.9", the DR's rocker angle is almost perpendicular to the pivot point, thus riding in the most progressive part of the arc and causing harshness on small bumps and bottoming on larger ones. When the rocker continued over center, progression became less and less the farther the suspension compresses. Then BANG!!!, it reaches the stop on the shock, and over the bars we'd go as the stop had no sign of rebound control.

To address these traits, we had to either change the configuration of the rocker, the links, or the pivot points. The simplest and least costly being changing the working length of the links. (Sometimes referred to as "Dog Bones"). 

After building and trying many different lengths, we settled on one size for most riders, but we build 3 different lengths for specific conditions and or riding styles. Most riders over 165lbs will require a heavier spring unless improved two-track is in the majority of the riding.

The different-length links give a much plusher ride everywhere, increases usable travel, all but eliminates the rear kick, and only lowers the seat height when the swingarm is fully extended, making getting on and off easier, not to mention it will no longer highside over the sidestand when you dismount. The laden seat height will remain the same when the recommend sag of 2.5" is used.

If the links are used for lowering purposes only, the sag can be set at 3.9" and the front is lowered by 1.25" to stay close to the stock geometry.

 After we learned how to "cure" the DR's rear suspension problems we decided to dedicate ourselves to helping riders of not only DR's, but also CRF's, DRZ's, KDX's, KX's, WR's, XR's, and even a few of the KTM's,  too mention a few. (All available products are either listed on the column on the left or on our order form link below.)  And the rest, as they say, is history.

 We give a 30 day money back return policy for any reason, no questions asked.  All our  Links are "CNC'd"  out of 6061 T6 aluminum and are considerably stronger than the cast OEM links.   For those of you who are motocrossing your bike, we cannot help unless you plan to re-spring the rear to handle the additional leverage of the longer KoubaLinks unless you are under approx. 160 lbs.  For  those who ride Enduros, Trailride, Dualsport or do Baja-type riding, our Links are a must -- your feet will come closer to touching  the ground during the day and your backside will thank you everynight!!

That's our story and we are sticking to it.  Thanks for taking the time to read it.
