Got my new belt quick ? What way should the arrows point?  towards secondary or primary stupid ? I know but never changed one b4

[2015 Z Force 800 53/Trail EPS]

The direction of rotation. usually toward the primary.

Yesterday I got my new belt for ZForce 500 EX (manufactured in 2016). It's a Bando (from the dealer).
I've just noticed that the belt has not rotation indicator (an arrow or something else) anywhere on it.
Any idea how can I figure the mounting position

I watched a video not long ago, if I remember it was Ultimax belts. They talked about the direction & why it was no longer important today with manufacturing & design capabilities.

I'm sure they did mention if you removed it, reinstall it in the same direction......not 100% sure on that one.

from what i heard it dosen't matter witch direction yoou put it on. it's more important to put it the same way when you have removed it and installing it again. If there are arrows put them the way the belt rotates. if not it dosen't matter wich way.
