Walt  Siegl definitely knows how to put out a nice custom Ducati.  His  'leggero' customs are all are stunning, and this one here, commissioned  for Puma is no different.  The base motor is a '93 2-Valve Ducati 900 SS  which is now blue printed BCM 944 big bore unit.  
The bike has a full carbon kevlar body and chromoly frame weighing a combined 30 lbs.  The exhaust is a custom stainless steel system with an Italian Mivv muffler. The electrical system is minimal and built around a Motogadget m-Unit to get rid of all the relays.
The  Puma Ducati is currently at the Puma International offices in Boston,  USA but hopefully it gets to see some track time too.  It's clear that  bike was built to run a track or open road - not collect a runway.
