This is also a function of pulley diameter. I am not familiar with 987's setup, but from what I remember they use pulleys at least 30 tooth, not tiny like 24 tooth or smaller.

I (and many other teams) have had some problems with 24T pulleys, 9mm belts, direct driving 6wd from the center etc etc. It's right on the margin of can or can't work, and it depends on how careful the user is. I don't like my drives to ride the safety margin that closely.
