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.
