DescriptionThe whole story▼

Enduro riding does not stop in winter, and a Yamaha WR250F used from November to March faces cold mornings, wet rocks and long road transfers in the rain. For the WR250F of 2018 to 2021, Accossato offers its AGPA110 front pad in the Sintered (ST) compound. This version is designed for riders who head out whatever the weather and need a front brake that responds consistently whether the disc is cold, hot or wet.

Key Features

  • AGPA110 front pad in Sintered (ST) compound
  • Listed for the WR250F, 2018 to 2021
  • Constant grip at low and high temperatures
  • Good bite on a wet disc, per Accossato
  • Designed for all-season riding
  • One box, one front caliper
  • OR and STMX also listed

Construction and Material Quality

According to Accossato, the Sintered compound maintains a high, constant grip level at both high and low temperatures and grips well in the wet. On a winter enduro ride, the brake moves between those conditions constantly: cold on a frozen road transfer, then hot after a long rocky descent.

Cold, Wet Trails

On a January trail ride the WR250F front brake is often cold and wet for long stretches. A sintered pad responds quickly on a wet disc, which gives the rider confidence when approaching a slippery rock step or a wet root section. On a cold morning, it does not need to warm up before working well. The lever point stays similar as the brake heats up on long descents, helping the rider maintain a steady rhythm. For all-weather riders, ST offers that consistency.

Road Transfers in the Rain

Enduro rides often include tarmac between trails. In the rain, a front brake that responds immediately is important. ST is designed to give that response.

Fitment and Compatibility

AGPA110 is listed by Accossato for the WR250F from 2018 to 2021, including the ENDURO GP of 2018. For 2003 to 2018 the front pad is AGPA51, and for 2022 to 2026 it is AGPA288. Since 2018 is listed for both AGPA51 and AGPA110, check your existing pads. The rear pad is AGPP106. One front caliper means one box. Accossato also offers the DK111, DK168, DK268 and DK269 discs for this bike.

Road Approval

No German ABE or test mark is on file for this pad. It is sold for competition use.
