I have been loaned a Monster 659. My impressions from a short ride in traffic:
Much better suspension.
Better exhaust sound.
Not the sort of riding position I'd like for around town. Ooh, me wrists. Ooh me back!
Clutch took some getting used to and it takes a lot more revs to pull away cleanly than the Scrambler.
Idiot lights (neutral, turn) hard to see in bright sunlight.
Not a bad bike but probably for a 20-something monkey, not a mature gent like one's self.
