Benelli 350 RS and 354: history and buying advice
350 cc fours, made for the Italian tax rules.
History
In Italy you paid much more tax on motorcycles over 350 cc. So alongside the 500 Quattro Benelli also built a four-cylinder 350 version: the 1976 350 RS. The engine closely resembles the 500’s, but with a smaller bore and stroke.
Around 1978 came the 354 and 354 Sport, with new styling. Touring and sports versions continued until the mid-eighties. Outside Italy they are rare. For anyone looking for an affordable Italian four it is a fun choice, but parts take patience.

What to check when buying
- Many parts are the same as on the 500 Quattro, but pistons and cylinders are not. Ask what has been replaced.
- Synchronise the four carburettors; a poorly running engine is often down to that.
- Check the electrical system and the charging voltage.
- Look for rust on exhausts, frame and chrome.
- Look for an owner who includes spares or a workshop manual.
