I think that's an excellent idea. Weight combined with heat may be the answer to some belts snapping too early.
I weigh 176lbs / 80 kilos.
Let's hear it!
Type of riding, weight load and things like that have no impact on belt durability whatsoever.
I would attribute durability and premature snapping only to the
manufacturing quality. Nothing else.
p.s. I weigh 240+ lbs, often rode with gf and baggage in excess of 440 lbs total, People's belt was changed at 15.000 kms and was still within specs, no cracks. The same with all my previous scoots. Agility's belts are changed after 12.000 kms and they are always good EXCEPT the one that snapped 5 miles after it was changed!
