I've seen waaayyy worse damage on belts that've continued to drive their (other brands of) motorcycles for tens of thousands of miles like that without any concerns, so I'd go with PinkRosePetal on this. :thumbup:
But I would recommend
strongly that you should
VERY CAREFULLY check the teeth on both the front & rear pulleys for damage! Anything hard enough to get pushed thru the belt like that may have also messed up some pulley teeth in the process, and unless they are cleaned up pdq with a (light) file, you could be damaging the belt more with every pulley rotation! :shocked: Of course, if either of the pulleys has teeth chewed up enough to warrant replacing that pulley, then you might as well replace the belt too. :2thumbs:
Still, it's clearly your choice, and if just knowing that it's there is going to worry you enough to lessen your ryding enjoyment, then sure, replace away!

But seriously, these belts are pretty tough things with some 'self healing' capability as well as being up to continuing ably in their role with relatively minor damage like that you've shown us, &/or with pretty much anything short of missing entire teeth or chunks out of either side of the belt leaving frayed & torn strands exposed, so I really wouldn't think replacing the belt at this stage is absolutely
essential given what you've shown us, with the the only caveat being that there's no damage to any pulley teeth! But it
is your choice.... :dontknow:
