DescriptionThe whole story▼
Deep sand tracks such as those on the coast or in heathland regions are brutal on motocross brakes, and a KTM 350 SX-F ridden there comes home with a caliper full of grit. Accossato makes its AGPA29 front pad in the Off-road sintered mixture, code STMX, and lists it for the 350 SX-F from 2011 to 2026. It is the brand's compound for off-road riders, aimed at racers on sand and clay tracks who wash their bike after every session and need brakes designed for dirt.

Construction and Material Quality
Accossato describes STMX in a single line: its compound for off-road riders. The lining is fitted to the standard AGPA29 plate. Across its range the firm also emphasises long life, limited fading and strong braking performance, all welcome on a motocross bike that is ridden hard in abrasive conditions.
Deep Sand and Heavy Clay
Sand tracks form deep, rolling ruts and braking bumps, and riders hit them hard lap after lap. The front brake is used repeatedly while the fine sand scours the disc and pads. Clay tracks create a different problem: sticky mud that packs into the caliper. A compound developed with off-road riding in mind is meant for both. For the 350 SX-F rider, that means a front brake designed for the environment the bike is built for.
Clean the bike after every session, rinsing the caliper at low pressure. Check the lining before each race weekend, since sand can wear pads quickly, and clean the pistons before pressing them back when you fit a new set.
Fitment and Compatibility
Accossato lists AGPA29 for the front of the SX-F 350 from 2011 to 2026. The rear pad for this model is AGPP80, and the discs DK017, DK018 and DK259 are also listed. With one front caliper, the 350 SX-F needs one box. Please compare pads before fitting.
Road Approval
We hold no ABE or German test mark for AGPA29STMX, which is intended for off-road racing.
