Just because it can be flown at 200 knots, doesn't mean the Vne will be anywhere near that.
The 139 can fly well in excess of 167 knots, hell, it will climb at 100Pi and 167knots, but that is where the Vne is set. Partially due to bird strike limits on the plastic windshields.
Will be interesting to see where Bell set the Vne on the 525 after testing is completed.
