Benelli 254 and 304: history and buying advice
A four-cylinder of only 231 cc, with the instruments in the tank.
History
The 254 was shown at the 1975 Milan show as the 250 Quattro: the smallest four-cylinder ever built in series. Lino Tonti drew the engineering, Paolo Martin the looks. The engine has a single overhead camshaft and revs to almost 12,000 rpm.
Striking are the instruments and brake master cylinder set into the tank, leaving the handlebar clear. As a result the tank holds only 8.5 litres and you do not get far. Moto Guzzi sold the same bike as the 254, with a different tank and wheels; fewer than 1,000 of those were made. In 1983 came the Benelli 304 with a double cradle frame. The 254 was expensive and sold modestly, but is now a sought-after collector’s item.

What to check when buying
- Check the instruments in the tank; moisture and broken plastic are common.
- Four small carburettors must be properly synchronised; check that it idles smoothly.
- Listen to the cam chain.
- Plastic parts are hard to find. Check that everything is complete and intact.
- Much of the engineering is the same as on the Moto Guzzi 254; search under that name too.
