Pros and Cons in comparison

Aprilia Tuono 660 2021

The Tuono delivers on the bends what the name promises. The sporty naked bike rides precisely and you enjoy the sporty corner chase. At the exit of the bend, however, one wishes for more emotion and adrenaline. The sporty expectation is naturally also created by the Tuono's racy appearance and cheeky demeanour. But this expectation is unfortunately not quite fulfilled in the saddle.

Easy-to-operate engine with good sound

successful appearance sporty handling

good ergonomics

decent brakes

extensive electronics - but partly at extra cost

stable and precise chassis

Price / performance ratio not right

IMU package costs extra

KTM 125 Duke 2021

Even in the Euro 5 version, the KTM Duke 125 is the motorbike to beat in the A1 class. Superior equipment, potent engine, good chassis, great display and fun Supermoto mode make not only the heart of 16-year-olds beat faster. The looks polarise, but let the observer clearly recognise the smallest Duke as such. The Duke 125 is not cheap, but it is worth the price.

lively engine

super-agile handling

Supermoto mode as standard

mature chassis

top brakes

sharp TFT display

connectivity (optional)

Optics not to everyone's taste

price high for a 125cc bike
