A Scotts damper has now graced my last eight motorcycles: four KTMs, two KX250s, one Gas Gas and a Beta 300RR. Each install was unique for a variety of reasons. Sometimes the damper towers were challenging to mount. Other times mounting components were difficult to locate in the aftermarket. Occasionally I had to buy a different upper triple clamp. But with a healthy dose of time, money and patience, the damper projects all came together and worked well. Except for that time the damper fell off and I never found it. But I digress.
In my early years of damper installs, dirt bikes often came equipped with 7/8" diameter handlebars. These had crossbars which were usually too low to clear a steering damper mounted to the top of the handlebar clamp. My solution was to upgrade the bars to the tapered style which have 7/8" diameters at their ends, but larger diameters where the bars meet the triple clamps. This style of handlebar does not have a crossbar and doesn't interfere with a top-mount steering damper.
Some of my dirt bikes came with bar mounts solidly connected to the upper triple clamp. Others were outfitted with bar mounts bolted to the triple clamp. Either way, the stock bar mounts were incompatible with the larger-diameter tapered handlebars. If I was lucky, I could simply buy a new pair of bar mounts and bolt them on. But if the bar mounts were forged into the triple clamp, I had to buy a whole new triple clamp.
Next up was finding a proper handlebar clamp on which to mount the damper unit. As shown in the photos above, a variety of options are available to make that happen. With triple clamps that came with adjustable handlebar positions, the damper mount had to be compatible with the bar mount locations or else it wouldn't line up correctly with the damper tower. Communication with vendors was key to finding the correct fit.
More recently, motorcycle manufactures are equipping dirt bikes with crossbar-less handlebars, which reduces damper installation headaches. Even with no crossbars, some manufacturers outfit their bikes with rubber mounted bar mounts to reduce vibration in the handlebars. This is a no-no with the Scotts damper, as it needs the damper unit and the tower to integrate with no flex.
Damper towers are usually the final challenge of the install process. The simplest towers clamp onto the steering head. These can be adjusted easily and installed without welding skills. I've had varying levels of success with clamp-on towers, depending on how much surface area is available for the clamp to grab onto. My pair of Kawasaki KX250 had small contract areas around their steering heads, and eventually I was forced to weld the towers to the frames. Later-model KTMs have more surface area around the steering head and work much better with the clamp-on towers.
