Ducati’s darkest hour proved to be a catalyst for one of its most elusive and coveted models – the 125 Regolarita Six Days. Launched in 1975, this rare gem was part of Ducati’s attempt to gain traction in smaller displacement markets, where it had previously struggled.
The 124cc two-stroke single engine, mated to a six-speed transmission, provides a unique blend of punchy power and engaging character. Weighing in at a sturdy 238 pounds, the Regolarita exudes a sense of rugged reliability that’s hard to find in modern motorcycles.
Today, collectors are clamoring for this elusive model, with auction prices reaching as high as $8,333 – a testament to its rarity and enduring appeal.
