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!
