DescriptionThe whole story▼

Deep sand tracks and heavy mud are the toughest test for a Kawasaki KX250F rear brake, with the caliper buried and grit grinding over the disc every lap. Accossato's AGPP106 rear pad in Off-road sintered mixture, coded STMX, is designed for that. It fits the KX250F from 2004 to 2018 and in 2020 and is aimed at motocross racers who ride on sand, clay and mud and want a rear brake made for dirt.

Construction and Material Quality

Accossato presents STMX as its compound for off-road riders and gives no further detail, so neither do we. The company's general claims for its pads, slow wear, limited heat build-up that keeps fading down and strong stopping power, apply as well. The compound is bonded to the AGPP106 plate for the rear caliper of the KX250F.

Sand Tracks

Riding a sand track on a KX250F is physically hard, and the rear brake is used constantly to control the bike in deep, shifting ruts. Sand is abrasive, and it finds its way into the caliper within a few laps. A compound intended for off-road racing is built to work in that grit.

Clay and mud tracks bring their own problems: the caliper packs with dirt, and the disc is coated in a layer of slurry. A rear pad designed for dirt keeps the pedal response usable when conditions are at their worst.

After racing on sand or mud, wash the bike thoroughly, rinse the rear caliper, check the pads for uneven wear and look for grooves on the disc. Clean the piston before pushing it back for a new set, and pump the pedal until firm.

Fitment and Compatibility

Accossato lists AGPP106 for the rear of the Kawasaki KX250F for model years 2004 to 2018 and 2020; 2019 is not included in our data for this pad. The front takes AGPA51, and the DK060 disc is also catalogued. The box covers the single rear caliper.

Road Approval

We have no ABE or German test mark for AGPP106STMX. The pads are sold for off-road competition use.

Scope of Delivery
