KTM 690 Duke 2017

KTM 690 Duke 2017

Considering where the KTM Duke family once started, the 690 Duke is an incredible step forward. The engine is extremely refined and at the same time husky for a street-legal single-cylinder. Despite all the technology on board, it is still a very light motorbike and can almost be called a toy (in a good sense). Only its seating position divides opinions, because with the Duke 4 in 2012, the former supermotos became an almost tame naked bike with a front-wheel-oriented seating position. The advantage: everyday life and long tours should not be a problem on the current Duke.

Aprilia SX 125 Supermoto 2021

Aprilia SX 125 Supermoto 2021

Aprilia's SX 125 is a very sporty supermoto that does justice to Aprilia's long 125cc history. Its 15 hp single-cylinder inspires with its balanced character with high suitability for everyday use, but at the same time provides a lot of fun under the helmet. The biggest advantage it has over the competition is its ABS system, which only acts on the front wheel and was installed instead of a CBS system. This makes it possible to conjure up beautiful drifts on the asphalt, as befits a true supermoto.

ABS instead of CBS
