SC3 Adventure Specs
Extend the thrill of the ride to off-road terrain and explore the world!
| Sustainable Design Our SC3 Adventure patented designs reinvented the 2003 H-D® Sportster® motorcycle by transforming the H-D® Sportster® into true on/off road dual sport motorcycles. |
| Designed by Feel & Experience With 44+ years of motorcycling experience riding, racing, customizing and over 34 years of design engineering experience, I developed the architecture and geometry of the SC3 Adventure dual sport motorcycle until it met the requirements for function, feel, then and only then: aesthetics. No compromises. |
| Closed Loop Precision Engineering The bike was hand built and tested both on and off road. Components were precision designed with 3D CAD, stress FEA analyzed as required, and CNC machined. As needed, designs were iterated until they met the requirements of fit, function, feel, and aesthetics. No compromises. |
