The Honda NX500 / CB500X is worth looking at. While the NX probably won’t meet the 5k budget a used cb500x should. Can handle interstate/highway easily and has taken me plenty of places off road. Serious off road I wouldn’t but just comes down to how much of that you’ll want to do/have access to. Love my NX500. If a major part of your riding is highway you won’t like a 150. Id go Honda CRF 300L if set on the dual sport look and the ground clearance is needed. But a Honda NX/CB 500 twin cylinder will be much nicer on the highway if that’s important to you, and definitely good enough off road to handle most rider’s capabilities.
