Aprilia Tuono 125 2018

The Aprilia Tuono 125 remains a very competitive A1 naked bike even with the tough competition from the 2018 model year. Thanks to its stable chassis and high-quality chassis components, it is a real fun machine in twisty terrain - especially if you have installed the 166cc conversion kit. However, its looks and instrumentation are starting to put it behind the competition, which is already coming up with technologies such as TFT and LED. Nevertheless, the Aprilia Tuono 125 is still a good tip for sporty, ambitious 125cc riders.
