Friend, my world is "orange"....
BUT, sounds you want to go on the highways, more speed, more cruseing? Then forget the KTM one cylinder bikes, they will shake you off the bike. From 120 kmh onwards stability will get weaker etc.
Either you try the more stable 2 cylinder versions or you should leave the orange world.
Ah, by the way, if you only think of hitting some back-roads with harder terrain, then you are back entering the "orange world"...
Cheers and have fun.
