Pros and Cons in comparison

Aprilia RS4 125 2014

Unfortunately, our editors did not test this model.

Yamaha R125 2014

In the course of our 125cc special, we tested the Yamaha YZF-R125 together with "Psycho Philipp" on the kart and supermoto track in Wöllersdorf. This year we were already on the road with Yamaha's eight-litre supersports bike at the Pannoniaring at the Gripparty and were able to convince ourselves that it can even stand up to its full-grown peers. On the miniature ring of the "Actionsracers", the little super sports bike was then really in its element.
