Benelli 504 and 654: history and buying advice
The last fours from Pesaro: 504 Sport, 654 T and 654 Sport.
History
At the end of the seventies the 500 Quattro got a new look as the 504 Sport. Around 1980 a bigger version followed: the 654 Turismo, and in 1982 the 654 Sport. The engine got the same bore and stroke as the 900 Sei, but with four cylinders: 604 cc.
Riders found the 654 fast enough, but there were also complaints about vibration above 7,000 rpm, rust and electrical faults. Soon after, Benelli got into ever deeper trouble; in 1988 the factory in Pesaro was sold.

What to check when buying
- Check the oil level and ask about the maintenance; engines have seized through lack of oil.
- Look for rust on exhausts, headlamp rim, frame and springs.
- Test the gearbox thoroughly; shifting problems occur.
- Check the electrical system.
- An intact 654 Sport is rare; a well-maintained example is worth more than a cheap project.
