“Men don’t stop playing because they get old, they get old because they stop playing.”
Oliver Wendell Holmes

The TrailBike Sportsmen Association is a family oriented off-road vehicle club whose main activity is recreational trail bike riding in some of the most scenic areas of northern and central California. Our members include riders of all ages and abilities. If you are looking for others to ride with and would like the company of fellow off-roaders, we invite you to join us.

TBSA is a nonprofit organization promoting recreational motorcycle trail biking. Our monthly camp outings include organized trail rides for all levels or riders, including three-wheelers and quads. Some of the events held at outings are poker runs, an annual Bikana, potlucks, social camp fires and occasional volunteer work for the U.S. Forest Service. We are active participants in the legislative process.

TBSA was incorporated in 1963 at the suggestion of writer Erle Stanley Gardner. There are presently three Chapters: The Sacramento Chapter, The Diablo Chapter, and The Motherlode Chapter.
