DescriptionThe whole story▼

Muddy race weekends leave the rear of a KTM 350 SX-F coated in a layer of earth so thick the caliper disappears. For that environment Accossato makes its AGPP80 rear pad in the Off-road sintered mixture, code STMX, listed for the 350 SX-F from 2011 to 2026. It is the brand's compound for off-road riders and is aimed at club and national racers who ride in whatever the weather brings and treat washing the bike as part of the race routine.

Construction and Material Quality

Accossato's own description of STMX is short: the compound for off-road riders. The lining is mounted on the regular AGPP80 plate. The Italian company, which took an Enduro World Championship title in 1985, also highlights long life, limited fading and strong braking across its pads.

Mud Races and the Paddock Routine

On a muddy race day, the rear brake of a motocross bike can be packed solid by the end of a moto. The pads work through a paste of water and earth that would glaze or wear a road compound. An off-road pad is designed with that in mind. Between motos, riders often have little time: a quick rinse of the rear brake, a check that the wheel spins freely and a glance at the lining are enough to confirm the bike is ready.

After the race, wash the caliper carefully at low pressure and let it dry. Before the next event, inspect the lining and disc, and clean the piston before fitting a fresh set. A worn rear disc should be replaced with new pads to restore full contact.

Fitment and Compatibility

Accossato lists AGPP80 for the rear of the SX-F 350 from 2011 to 2026. At the front, AGPA29 is listed, and discs DK017, DK018 and DK259 are also offered. Please compare the pad shapes before installation.

Road Approval
