DescriptionThe whole story▼

Sand tracks are where a torquey two-stroke like the TM Racing MX 300 can really use its pull, and where the rear brake gets blasted with grit. For the MX 300 two-stroke from 2005 to 2025, Accossato offers the AGPP106 rear pad in STMX, its compound for off-road riders. It is intended for riders who race and train in sand, mud and dust and want a rear brake designed for that environment.

Construction and Material Quality

Accossato calls STMX its compound for off-road riders without adding technical details. We follow that description. The company's general aims for brake pads, low heating to prevent fade, long wear and strong braking, apply here too.

Sand and a Big Two-Stroke

On a deep sand track, the MX 300's torque helps the bike drive through the soft ground, but the rear brake is constantly exposed to abrasive sand thrown up by the tyre. The rider uses it to set up corners and control the bike in whoops. The Off-road sintered STMX mixture is designed for exactly that kind of contamination. It is also suitable for muddy and dusty conditions. For dry or wet but clean tracks, OR and ST are the alternatives on this plate.

Checks After Sand

After a sand race, remove the rear pads if possible, clean the caliper thoroughly and check the pistons for smooth movement. Sand wears pads faster, so check the thickness more often than usual.

Spares in the Van

Riders who travel to sandy circuits often pack a spare set of rear pads. Changing them in the paddock takes only a few minutes and avoids starting the next race with a pad that has already lost much of its material.

Fitment and Compatibility

Accossato lists AGPP106 for the rear brake of the TM Racing MX 300 two-stroke over 2005 to 2025. The front plate for the same bike is AGPA29, listed from 1998. Bikes built before 2005 have no rear pad in this list.

Road Approval

AGPP106STMX comes without ABE or approval documents. It is intended for motocross and enduro competition.

Scope of Delivery

Two STMX rear pads for the MX 300.
