Technology / Motorcycle / Die-Cast Controlled-Fill Aluminum Frame: Alloy frames featuring large one-piece sections constructed with a high-vacuum mold process, reducing porosity and eliminating air pockets that can result when pouring molten aluminum. These large sections are then combined with a minimum of welds, or even bolted together, to create the frame. The result is a lighter, more rigid, more finely tuned frame of higher production quality.
