DescriptionThe whole story▼
When a KTM 350 EXC-F is raced in enduro, its rear brake is working in the worst place on the bike: low down, right behind the tyre, in the path of all the mud and sand. Accossato's AGPP80 rear pad in the Off-road sintered mixture, code STMX, is its compound for off-road riders, and we list it for the 350 EXC-F from 2012 to 2023. It suits racers and dedicated trail riders who ride in heavy mud, sand and water, and who clean their bike thoroughly after every outing.

Construction and Material Quality
Accossato presents STMX as its off-road compound. The lining is fitted to the standard AGPP80 plate. The firm, founded in Moncalieri in 1969, also names long life, limited fading and strong braking as goals across its pad range, which fits the heavy use of a rear brake in enduro competition.
A Day of Enduro Stages
Between the start of an enduro day and the final time control, a rider covers many kilometres of liaison and several timed tests. The rear brake gets used constantly in the tests: to settle the bike before a corner, to drop down a bank, to control the rear wheel on a slippery climb. In mud and sand, grit is always present. A compound meant for off-road racing keeps performing through that, which gives the rider confidence to keep pushing late in the day.
In the service area, check the rear caliper for packed mud and look at the lining. After the event, rinse the brake gently, let it dry, and clean the piston before fitting new pads. Keeping a spare set in the toolbox is a sensible habit for longer events.
Fitment and Compatibility
We list AGPP80 for the rear brake of the KTM 350 EXC-F from 2012 to 2023; Accossato's list starts in 2011. The front partner is AGPA29, and Accossato also offers discs DK017, DK018 and DK259 for this model. Hold the old and new pads together before fitting.
