DescriptionThe whole story▼

Once a SuperLow owner has settled in and starts riding the bike more purposefully, carrying a pillion on occasion or simply covering more miles through a typical year, the softer Organic rear pad can start to feel a little short on grip in the wet, and Accossato's Sintered (ST) compound for the XL883L, built from 2014 to 2018, is the step up built for exactly that stage.

Key Features

  • Sintered (ST) compound for the Sportster 883 SuperLow XL883L rear caliper
  • Listed by Accossato for model years 2014 to 2018
  • High, constant grip claimed by the maker at hot and cold temperatures
  • Keeps biting once the disc has picked up rain
  • Suited to more confident, higher-mileage riding
  • Alternative OR rear compound exists for the same caliper
  • Two pads per box, enough for one rear caliper

Construction and Material Quality

Accossato's pitch for this ST mixture is consistency across a wider range of conditions than the Organic option offers: much the same grip whether the pad is cold or has been working for a while, and no drop in bite once the disc is wet. That extra margin is useful once a SuperLow owner starts asking more of the bike, whether that means a longer ride in changeable weather or simply more miles ridden with more confidence than when the bike was new to them.

Growing Into the Bike

The SuperLow is often a rider's introduction to Harley ownership rather than a bike they outgrow quickly, but braking habits and mileage both change as confidence builds, and a firmer, more consistent rear pad suits that shift better than the softer compound the bike may have started out with. This Sintered set holds its character through rain, cold mornings and the extra weight of a passenger alike, rather than needing calm, dry conditions to feel dependable.

Fitment and Compatibility

Accossato lists this ST rear pad for the 883 SuperLow XL883L built between 2014 and 2018; confirm your exact year carefully before ordering, since fitment is not shared with other Sportster variants despite similar part numbers. The softer Organic compound remains available for the same rear caliper for riders who still prefer that gentler, more forgiving character over this firmer, all-weather alternative.

Road Approval

No approval paperwork, such as a German ABE or a type approval mark, is available to us for this pad, so it is listed for racing and competition use where such documentation is required for road riding. Please check your own country's rules first.

Scope of Delivery

Two brake pads in the box, one set for a single rear caliper. Mounting hardware such as pins or springs is not part of the package.
