Ducati Monster 900: classic naked, versions and what to check
Ducati Monster 900 — the legendary Italian naked bike with an L-shaped twin-cylinder engine, produced from 1993–2002. We look at the versions, engine, and what to check when buying a used motorcycle.
Monster 900 in brief
Monster 900 — the Ducati naked bike that started the entire Monster family. It stands out with its tubular frame, open engine, and simple yet striking appearance.
Today, it's already a classic motorcycle, so it's valued by collectors and enthusiasts. Condition and service history are more important here than the year.
Versions — what's the difference
The earliest Monster 900s (from 1993) had carburetors. In the later production years, a fuel-injected version appeared (Monster 900 ie).
There were several color and styling versions, for example, the Monster 900 Dark with matte black paint. Higher-end S versions were also offered.
Engine and transmission
The engine is an air-cooled 904 cm³ L-shaped twin-cylinder Desmodue, with around 70 hp. It's got a distinctive character and is strong at low revs.
The gearbox is six-speed (previously five-speed), with a dry clutch, and chain-driven. The dry clutch is typically harsh, but that's normal.
What to check when buying a used Monster 900
Ducati engines have timing belts that must be changed according to the manufacturer's schedule. Ask when this was last done and when the valves were last adjusted.
Check the engine for oil leaks, inspect the charging system and electrics. Check the carburettor or fuel injection system.
Inspect the chassis, suspension, brakes and exhaust system for corrosion. Check the documents and numbers.
