DescriptionThe whole story▼

The back brake on a racing Husqvarna FC 350 works hardest where the track is roughest: braking bumps before a hairpin, choppy downhills, deep sand turns. Every one of those places sprays grit onto the rear caliper. Accossato's AGPP80 rear pad in the Off-road sintered (STMX) compound, catalogued for the FC 350 from 2014 to 2026, is the brand's dedicated off-road mix. Accossato describes STMX as its compound for off-road riders, and it is aimed at racers and hard trainers who want a rear pad chosen for dirt.

Key Features

  • STMX rear pads for the Husqvarna FC 350, 2014 to 2026
  • Accossato's compound made for off-road riders
  • For braking bumps, rough downhills and sand turns
  • Fits the AGPP80 rear caliper of the FC 350
  • Two pads, one set for one caliper
  • No German ABE; for use in competition

Construction and Material Quality

For the AGPP80 plate, STMX is Accossato's off-road option. The company describes it simply as a compound for off-road riding. It shares the backing plate with the OR and ST rear variants. The brand claims across its pad range that wear stays low, that restrained heating keeps fade in check and that braking power stays high, and dirt racing tests all three properties harder than most disciplines. Accossato won the Enduro World title in 1985, so off-road use sits deep in the company's history.

Rough Ground and Rear Control

A braking-bump section is where a rear brake either helps or hurts. The wheel is skipping off the ground, and every time it lands the pad needs to grip again without locking. A stable, predictable response makes it easier to keep the bike straight. In sand turns, riders drag the rear slightly to tighten the line; on long downhills they use it to control speed without overloading the front. All three situations wear pads fast, so check them at every race and clean the caliper after every wash. Push pistons back only after cleaning them.

Fitment and Compatibility

Accossato lists this rear pad for the Husqvarna FC 350 in every year from 2014 to 2026. The front pad for the same bike is the AGPA29, and the brand also offers the DK017 and DK018 discs. On the rear plate the alternatives are OR and ST. The FC 350 has a single rear caliper, so one box covers it.

Road Approval

There is no ABE and no test mark on file for these pads. We offer them for off-road racing only.

Scope of Delivery

A single box with two STMX rear pads for the rear caliper.
