Pros and Cons in comparison

Triumph Street Triple S A2 2021

Unfortunately, our editors did not test this model.

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
