At low levels, modest levels, and semi-loud levels, your Yamaha should have no problem at all powering the Monitor Audio speakers.
At ear-bleeding levels, or at loud levels in a very large room, it might struggle (ie, clip or go into auto-shutdown/self-protect mode due to thermal limiting).
Try it, and if it seems fine at the levels you like, it's good to go.
The Monitor Audio recommended 100-200 watts is kinda silly, by the way, unless they know just how loud you like to play them.
For every new thing I learn, I forget two things I used to know.
