DescriptionThe whole story▼

An enduro day on a Kawasaki KLX 450R can include deep mud in the woods, sandy special tests, dusty transfer sections and a river crossing or two. For that kind of riding Accossato makes the AGPA51 front pad in its Off-road sintered mixture, coded STMX. It fits the KLX 450R from 2007 to 2024 and is designed for riders who compete in enduro events or ride hard on demanding off-road terrain.

Construction and Material Quality

Accossato describes STMX as its compound for off-road riders, and that is the whole of its statement, so we make no further technical claims. The company's general promises for all its pads, low wear, resistance to fading through limited heat build-up and high stopping power, apply as well. The compound is bonded to the AGPA51 plate for the KLX 450R front caliper.

A Full Enduro Day

In an enduro event, the KLX 450R front brake moves from sticky clay to dry sand to fast gravel in a single loop. Mud packs into the caliper, water washes grit across the disc, and dust coats everything on the transfer sections. A compound intended for off-road use is designed for that environment, where road pads are not at home.

Riders who come from motocross sometimes rely too heavily on the rear brake on long enduro descents. A front pad that bites reliably in the dirt encourages a more balanced technique, which saves energy over a long day.

After the event, clean the bike thoroughly, rinse mud from the caliper and check that the pads slide freely. Look for grit scoring on the disc and measure the pad depth, as enduro days can use up a lot of friction material. Clean the pistons before pushing them back for a new set.

Fitment and Compatibility

Accossato lists AGPA51 for the front of the Kawasaki KLX 450R from 2007 to 2024. For the rear, the matching part is AGPP106, and the DK060 disc is also catalogued. Each box covers one caliper.

Road Approval

We have no ABE or German test documentation for AGPA51STMX. The pads are offered for off-road competition.
