Stop me if you’ve heard this one before: Italian aircraft manufacturer, banned from building planes after World War II, decides to focus on two-wheeled transportation. Sound familiar? You could choose from, among others: Piaggio (Vespa), MV Agusta or Aeronautica Macchi.

Giulio Macchi’s company built some of the world’s fastest aircraft in the interwar years and during World War II. In 1934, the Macchi MC72 set an absolute world record speed of 440.7mph that held for five years, and is still the fastest speed ever achieved by a propeller-driven seaplane.



Chimera

Much like Honda, Aermacchi had a Dream. On joining the company in 1956, chief designer Alfredo Bianchi was tasked with creating an all-new production motorcycle. Bianchi borrowed styling ideas from the automobile industry to produce a futuristic-looking motorcycle with fully enclosed bodywork that hid the mechanical components. These included a compact, lightweight 175cc 4-stroke engine and an ingenious swingarm rear suspension controlled by a single spring/shock unit.

While the Chimera (Italian for “dream”) created a sensation at the 1956 Milan show and was well received by the motorcycle press, it failed to impress potential buyers, and was an abject commercial failure (see Motorcycle Classics, March/April 2014).

This sounds like the bike I sold to Ron Lancaster at the Wauseon Ohio swap meet.It was built from a stock 1967 sprint ss. Having many racing sprint parts availabe, I made a 250 CRTT. It had a 5 speed trans from a 73 sprint , carb fron a xr750, Ceriani 35 MM r/r ft. fork,18 inch aluminum wheels, drilled brakes and a road race fairing.I needed more power so I installed an early long stroke crank with a short racing rod so I could keep the stock height cyl. It ran great. Wish I still had it. Tom Perko , n/e Ohio
