The Chimera was Aermacchi's lightweight 175 cc four-stroke sports-tourer, with a horizontal single-cylinder engine, an aluminium-cased unit construction drivetrain and a slim, stylish look for the period. It was aimed at the Italian everyday market and learners wanting something sportier than a basic commuter.
