That's my method for the pro-link as well as RFS smaller bore KTMs.
That as well as the method outlined in manual...
You will likely hear chain-slap when operating bike if tension is too loose.
Not sure about the bikes you mention, but on the 690, you just put it on the side stand and measure the tension. Basically you want it to almost, but not quite, be able to touch the swingarm.
