[OC] Brake pads on Ather 450X

The brake pads on my Ather are wearing out every 5000 km. I’m usually a pretty chill rider (I even keep the scooter in Ride mode most of the time, not Sport/Warp). So is this normal wear for the brake pads? The brake pads from Ather are also quite expensive. If it is normal, can I switch to sintered brake pads? Will they be better for braking performance and longevity?
