Aprilia Tuono 660 Factory Ex Demo. To be a Factory version means adding that extra level of technological excellence and ultimate riding enjoyment to the already ultra-high standards set by the Tuono 660. More power and less weight for improved performance is accompanied by a comprehensive electronics package and adjustable suspension so that you are always totally in control. The Tuono 660 Factory redefines the realms of possibility. Light on weight, heavy on performance The Tuono 660 Factory version benefits from an improved weight-to-power ratio, the result of a new lightweight lithium battery that contributes to reducing the overall weight by roughly 2 kg, taking the kerb weight down to 181 kg. Add this to fully adjustable front and rear suspension and you have an extraordinarily efficient bike that is hard to resist. A powerful statement on the road The maximum power is upped from the Tuono 660’s 95 hp to 100 hp with the Tuono 660 Factory. The engine boasts even more drive during acceleration, thanks to the use of a shorter final drive, with a 16-tooth pinion gear, one less than Tuono 660.
