Harley Davidson Stunt Builds

  • Full Frame Up Dyna Builds

    @2_slicc wanted to create a custom Harley Davidson Dyna, so we took the bike down to the bare frame for a thorough inspection. We checked the Dyna frame for any cracks or damage caused by the intense demands of stunt riding. Once we ensured the frame was in perfect condition, we powder-coated it in a striking blue to perfectly match the paint job on Slick’s Dyna, giving it both durability and a standout look.

  • Custom Wiring

    Jake is our go-to wiring expert, and for this Harley Davidson Dyna, we decided to build a completely custom wiring harness. The goal was to strip away all unnecessary wiring to reduce weight, especially since this bike is primarily used for stunt riding. By streamlining the harness, we removed a significant amount of weight and made future troubleshooting much easier. We like to call this the "race bike treatment," giving the bike a lean, efficient setup built for performance.

  • Dyna Suspension

    When stunt riding a Dyna, having top-quality suspension is essential. In fact, most stunt riders would agree that it's the most important part of any Harley build. Our Nowaskey Dual Adjustable shock is the best choice for a Harley Davidson Dyna, offering over 80 clicks of compression and rebound adjustment. What sets it apart is our ability to customize the spring rates to match 2Slicc's specific weight, ensuring optimal performance and control during every stunt.
