Aprilia RS 660 2021

In 2021, the Aprilia RS 660 can be seen as the last true 600cc supersport, because with its sporty seating position and high-quality chassis components, it hits the sweet spot between suitability for everyday use and trackday potential. Thanks to the comprehensive electronics package, nothing is left to be desired on the road or on the track - and you can't complain about the powerful two-cylinder anyway. A great package for all those for whom 200+ hp superbikes are too much for everyday use.

BMW S 1000 RR 2023

For me, the most noticeable of all the innovations were the electronics and the steering geometry. Thanks to the additional information of the new steering angle sensor and the revised riding aids, the new S1000RR now has an electronic package with which you can not only ride safely, but also quickly, which will especially please the faster faction. But with a few additional features such as Slide Control, the average rider also has the opportunity to try out the riding style of the pros without risk, in order to cut a good figure in riding photos. And apart from that, it's also fun. The new steering geometry brings a little more calmness to the front and improves feedback, which is an invaluable advantage, especially at the limits. So the next round in the hunt for the best superbike is reopened.

Very good electronics or control systems
