I have a 2020 SR/S with 38,000 miles. The original belt got a hole punched in the middle by a small rock after riding about 10 miles on a muddy gravel logging road. I kept going to avoid backtracking 30 miles. The road turned back to pavement and I thought I had gotten away with it but on inspection later I saw the damage. It didn't break. That was at 4,000 miles. Then at about 25,000 miles I rode on fresh Chip Seal and rocks were flying furiously so turned around but the belt snapped before I got back to clean pavement. I had the old damaged belt as a get home spare and just rolled that on without loosening the rear axle nut and rode home. You only need to remove the inner fender and disconnect the inline connector to the rear tail light and remove a couple of wire ties. The third belt is still on there. My feeling is that the belts are strong enough but easily damaged by road hazards. The belt will not stretch so it snaps if anything hard gets under it. Avoid gravel !!
