The bike is based off a 2003 Harley-Davidson Dyna Super Glide Sportax FXDX and if you look closely there are dual disk brakes, and the suspension is fully adjustable. Of course it’s got a custom paint job and the T bars but it’s a California model so it has the improved brake calipers. The front fairing is an Arlen Ness fairing and not the factory Harley Davidson fairing that was available for the Sportster/FXR/Dyna models (narrow glide models only). The FXDX is the sporty hotrod of the big twins, it’s got more cornering clearance then most sportster models and better forks/shocks than any other Harley Davidson. The rest of the FXDX bike is pretty similar to a regular Dyna Super Glide. And almost 100% sure that it’s got a Thunderheader pipe on it.
