Aprilia RS 660 2021

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.

Yamaha MT-09 2025

Yamaha MT-09 2025

Yes, Yamaha has produced a really leiwandes bike. All the criticisms of its predecessor have been successfully revised without neutering the wild and playful nature of the MT-09. The fourth generation is more mature, more precise and more polished, rides more neutrally and is more stable without losing its light-footedness. A marvellous bike that currently offers an almost unbeatable price-performance ratio thanks to many detail improvements and has now even become really pretty. The Yamaha dealers won't be able to save themselves from orders after test rides. Let's hope that availability is guaranteed, because the new MT-09 is the definition of the word "direct hit"!
