DescriptionThe whole story▼

Sand whoops, deep ruts, mud on the landing of every jump and dust hanging in the air on a summer afternoon: that is the environment of a Suzuki RM-Z 250 on race day. For this world Accossato developed its Off-road sintered compound, sold for the RM-Z 250 as the AGPA51 front pad with SKU AGPA51STMX and listed from 2004 to 2026. It is the mixture for motocross and enduro riders whose brakes are covered in dirt within the first lap.

Construction and Material Quality

Accossato presents the STMX compound simply as its mixture for off-road riders. It is designed for an environment where the pad works in grit, water and mud rather than on clean, dry tarmac. The maker also aims for low wear, controlled heat and strong stopping power.

Built for the Dirt

On a sandy track, fine grains get between the pad and the disc; in muddy conditions the whole caliper is packed with clay after a few laps. Crossing a stream on an enduro loop cools the brake suddenly and covers it with water. The STMX mixture is made for these conditions, where a road compound would be out of its element.

Riders on the RM-Z 250 who race motocross on sand or clay tracks, or who use the bike for enduro training, will find this the most appropriate choice.

Cleaning After the Race

After a muddy race, clean the caliper thoroughly with water and a soft brush, never with a pressure washer aimed directly at the seals. Check the pads for glazing and the disc for scoring before the next race.

Fitment and Compatibility

Accossato lists AGPA51 for the front of the RM-Z 250 across the years 2004 to 2026. The back wheel of the RM-Z 250 takes AGPP106, listed from 2004. The box contains the set for the single front caliper.

Road Approval

We do not hold an ABE or German approval document for AGPA51STMX; the pad is sold for off-road competition.

Scope of Delivery

Two front pads in the STMX mixture for one caliper.
