Those kinds of routes are dead easy for a coach as it's mostly motorway with the odd bit of city.
Compared to those routes the X9/X10 has considerably more start/stop driving, which is more strenuous on the drivetrain.
Well if you wanted to go for a stop start route then there's the 10 in Scotland between Aberdeen and Inverness and they both use versions of the Plaxton Elite and they don't have any issues that I know of and that's mostly express driving between towns on the A96.
There's no reason really why they can't do the X9/X10 imo unless there's something wrong with the coaches thereselves.
