This Ducati 900cc Desmodue powered motorcycle, known as Leggero, is built by master-craftsman Walt Siegl. If you’re familiar with Walt’s creations you know he is one of those rare craftsmen, that is so keen on attention to details, that it borderlines insanity. His bikes are the perfect balance of high-end materials powered by bulletproof power-plants, that provide the rider with the ultimate experience for the 4 senses, 5 senses if you plan to taste it. This Ducati 900 Leggero is the prototype of a limited run of production machines based on the thunderous two-valve Ducati 900cc engines. The idea behind this limited run was to build the same quality bikes with reduced costs. Walt once again succeeded in using the classic sport/racing design elements that are clearly recognizable, from exhaust to frame design.
The power-plant on the Leggero is a carburated two-valve Ducati 900cc engine fitted with 39mm Keihin FCRs. The heads and cases were polished to bring out the classical shapes of the Ducati 900 Desmodue engine. The frame is crafted from 4130 chrome moly steel tubing and it has exactly the same weight as the Verlicchi TT1 and TT2 frames—19 lbs, according to Walt. The frame and rear-sets were reverse-engineered by M&E Design. A Solidworks computer program has been created, which allows him to reproduce these designs. The Solidworks programs allow stress analysis to be done, it allows for the build of a superior product, it takes away the guesswork and reduces the time spent on research and he can be certain that what he is building is strong enough with pieces that will fit well together.
The exhaust pays homage to the Conti systems that the Ducati Bevels of the 1970’s had. Walt fabricated this Conti style exhaust system in stainless steel. Suspension is comprised of a Showa fork, and two rear Ohlins shocks. The bodywork is carbon fiber. Walt built the original tank and tail, then Matt Tanner (Tannermatic), used his prototypes to create molds for this and all future builds for the series. Through his builds, Walt has collected a group of very talented people to help him build the absolute best possible product. Besides Tannermatic and M&E Design, Walt works closely with Dave Goddard for painting, Eric
Kobalth Colbath of Clubhouse Motorsports for engine rebuilds, and seamstress Vivienne Smith for upholstery. Alex Vogel of AVA Restoration helps design a truly modern, fully electronic wiring harness. Although the bikes are still hand-built by Walt, one at a time, these technologies have shaved off many hours in the workshop building these Ducati customs.
Walt is known for other amazing quality builds such as: Ducati Riviera 900SS , Ducati Sport Classic, Ducati Monster Custom SC. If this Ducati Leggero (Superlight) is the bike for you, you’ll be glad to know that you get plenty of choices when it comes to customizing it. You can choose from a mono-shock or dual-shock set-up. There is a half-fairing option as well and the bodywork choices are: full carbon fiber, clear-coated or painted; or painted vacuum-molded fiberglass.
