VIPER PROPRIETARY ENGINES

---

The proprietary engine technology acquired by Viper Performance in early 2005 affords us the opportunity to offer multiple displacement engine sizes. We have completed extensive testing of our initial V-Twin 152 cubic inch engine. Both our Diablo and Diamondback cruiser lines will initially offer consumers this powerful 152 cubic inch engine to power the motorcycle they purchase. We believe that having our own proprietary engines will distinguish us clearly and favorably from other upscale custom V-Twin competitors.

Our proprietary V-Twin engines feature an all-billet aluminum construction including cases, heads, cylinders, rocker boxes, covers and oil pump components. Regardless of the varying rated power, our V-Twins will utilize the same crankshaft and stroke dimensions, with only the size of the cylinder bore creating the eventual different displacements.
