New Honda NC700X.
Perfect for everything...cheap...super fuel efficient. Probably last 300,000+ kms. It was engineered with exactly half of a Honda fit car engine. Low compression, hi torque, low revs, low stress. They aren't very light but the motor almost lays flat int he chassis making them feel as light as a Ninja 250 literally. Plus the fuel load is carried low under the seat and has a storage compartment where the tank normally resides, that is big enough for a full face helmet. If I were looking for a universal bike to travel the world, it would be a serious contender.
