Stillwell Performance specializes in making your dirt bike’s suspension work better for you, no matter your size or weight. The Scottsdale, Arizona-based business offers both suspension-related products and services, which means you just ship your parts to them and they do all the work. And they, of course, send it all back to you in a timely manner.

Owner Alan Stillwell is a nationally recognized expert in suspension tuning. He was the resident suspension expert on ThumperTalk.com, with over 400,000 members and has tuned for top factory teams and riders (MX, OFF ROAD, GNCC, WORCS & NATIONAL ENDURO).

Stillwell Performance has amassed 10 National and International #1 plates in the past 10 years. We have worked with a “who’s who” of top riders and teams.

In late 2011, after running a KTM Satellite Team for two years, Stillwell Performance was contracted by Factory Beta in Italy to manage their U.S. off-road racing program and build their bikes into championship winning machines.

While you might not ride a Beta, this is significant because it demonstrates our expertise in taking a previously un-tested bike and suspension and developing it into a winner. Factory Beta researched many companies before choosing Stillwell Performance.

We are well known as the top KTM, Husqvarna, and BETA tuner in the country but our expertise also stretches across all brands as well. As an example, Dirt Rider Magazine tested a bike Stillwell Performance built and proclaimed “Stillwell should be given an award for the work they did on the KTM suspension”

Stillwell Performance has also invented numerous motorcycle/suspension products, including the patented Linkage Guard, which won Dirt Rider Magazines prestigious “Best New Product” award in 2013!
