Pros and Cons in comparison

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.

KTM 1090 Adventure 2017

The KTM 1090 Adventure is a huge step away from its predecessor, the 1050 Adventure, towards its bigger sisters. The electronics package with adjustable riding modes, traction control and ABS remains at the already high level, but the engine now has 125 hp, around a third (!) more than the 1050. Almost more importantly, it can now rev freely to over 10,000 rpm and thus offers a more usable rev band. You will hardly find a more balanced bike in the class of still reasonably priced large touring enduros.

Very powerful, cultivated engine with wide rev range

performance modes

ABS can be switched off

adjustable traction control

agile and safe handling

adjustable ergonomics

height-adjustable windshield

low weight

comparatively low price.
