Our Story…
From our humble beginnings as McCully Engineering in 2004, we have grown to be Australia’s foremost custom Harley Davidson aftermarket parts specialists. After many years of building custom motorcycles, we switched our focus to where our true passions are: Creating the best products on the market. Since 2011, we have consistently produced innovative and creative components ranging from VROD swingarms to BREAKOUT rake kits to FATBOY rims and everything in between. We create our products through a stage by stage process from concept, to design, to modelling, to machining, and finally to a finished product.Check out our GALLERY here to see some of our products on builds.
