Building The Riviera Ducati SS With Walt Siegl

When Walt Siegl builds a motorcycle, motorcyclists, industrial designers and mechanical engineers sit up and take notice.

This new bike, the Riviera Ducati SS, is a phenomenal example of Walt’s work. Every element of the bike is unique, from the hand-fabricated chromoly steel frame to the custom moulded carbon/kevlar fuel tank to the one-off hand-made stainless steel exhaust system.

We’ve been chatting with Walt and he agreed to give us an exclusive look inside his workshop, so we can all see the process of taking a Ducati 900SS and turning into the finished motorcycle you see above and below.
