DescriptionThe whole story▼

For the Yamaha YZ125 from 2021 to 2026, Accossato's front pad AGPA288 comes in its Off-road sintered compound, SKU AGPA288STMX. This is the version for serious motocross use: race weekends, hard training on sandy or muddy tracks, and long motos where dirt, water and grit reach the front brake on every lap. It is designed for riders who push their two-stroke and need a front pad that keeps working through the whole day.

Key Features

  • STMX front pad for motocross, SKU AGPA288STMX
  • Yamaha YZ125, 2021 to 2026
  • Made for sand, mud and water
  • For race weekends and long motos
  • Front pad for dirt use
  • Two pads per box for the front caliper
  • Discs DK111, DK268, DK269 and rear pad AGPP106 listed

Construction and Material Quality

STMX is Accossato's compound for dirt, and on the 2021 to 2026 YZ125 it comes on the AGPA288 shape. The Italian firm, which started in Moncalieri in 1969, says of its pads in general that they wear slowly, hold off fade by keeping heat down and stop strongly. That is all we claim; the recipe itself is not something we describe.

Sand Tracks and Long Motos

Sandy tracks are hard on everything: the rider, the engine and the brakes. Fine sand gets into the caliper, and long motos keep the brake working lap after lap. On a YZ125 ridden in those conditions, the STMX front pad is the right tool. After the event, wash out the caliper, let it dry, check that the pistons move freely and measure the pad thickness. Riders who race sand regularly often carry a spare set in the van, because a long, gritty weekend can use up a set faster than a season of hard-pack. For mixed track and trail days, the ST version of this pad is more versatile.

Fitment and Compatibility

Model years 2021 to 2026 of the Yamaha YZ125 are where Accossato places AGPA288. The previous shape, AGPA110, is listed for 2008 to 2021, so anyone with a 2021 bike should compare the old set with the picture first. Only one box is needed, since the front brake has a single caliper. At the back, AGPP106 is the Accossato pad for 2003 to 2026, again with an STMX version, while DK111, DK268 and DK269 are the discs listed for the YZ125. Sand is the enemy of piston seals: flush it out of the caliper body before retracting the pistons, and make sure both pistons return evenly.

Road Approval

There is no ABE or test certificate on file for this pad. We sell it for racing and competition use.

Scope of Delivery

One box with two pads for the front caliper.
