Welcome rstoevo; congrats on the new-to-you HD train. It's one of a few bikes in the HD Softail line...others include Heritage, Fatboy, Deuce & Springer. Your bike's the more "bad boy" of the line-up and one of the best means to learn about your ride is to get a service manual and go through it. This way you'll get familiar with all the bike's systems, parts and controls. Enjoy & ride safe!
