According to MCN the new Multistrada is for folks who ride sports bike but wishes a touring bike, while the GS is.. well.. a proper touring bike.
Surprisingly the GS, albeit much less power compare to the monstrous Superbike based engine of the Ducati, can keep up with the Duc on the straight. But on twisty on-road asphalt road the Ducati simply pulls away. Understandably the big 19″ front wheel of the GS make it less agile, while the Ducati is using normal on road front tire.
The reign of the GS is seriously challenged by the new knight in town.. 🙂
