Mach 1

The Ducati Mach 1 is among the best-known Italian sporting singles of the 1960s. Its roughly 250 cc bevel-driven four-stroke, desmodromic valve gear, five-speed transmission and low weight delivered remarkable performance. Clip-ons, a long tank and rear-set footrests create a genuine clubman riding position. Small production changes and decades of restoration mean surviving examples vary considerably in detail, originality and behaviour.

Documentation and numbers determine value. Check frame and engine numbers, crankcases, cylinder head, Dell'Orto carburettor, tank, seat, mudguards, wheels and instruments against the stated year. Reproduction parts can be serviceable but should be priced honestly. Start it cold and listen for crankshaft, big-end and bevel noise; check smoke, compression, oil return and leakage. Ask about valve clearances, ignition and specialist rebuild invoices. Inspect tank and frame for corrosion, old weld repairs and incorrect geometry. Brakes and lighting are limited by modern standards.
