DescriptionThe whole story▼

Riders who take a Kawasaki KX450F to enduro-style training loops, sand dunes or muddy natural terrain tracks know how quickly a front pad can suffer. Accossato's AGPA51 front pad in the Off-road sintered mixture is listed for the KX450F from 2006 to 2022 and is the company's dedicated dirt compound. It is made for long, abrasive days where the disc is never truly clean.

Construction and Material Quality

Accossato's own description is concise: STMX is its compound for off-road riders. On a KX450F front brake, which takes dirt thrown up by the front wheel and tyre, that focus makes sense. The pad is designed for a caliper that is regularly packed with grit. Like all Accossato pads, it is built to keep heat and fade low and to stop firmly. The STMX material is bonded to the standard AGPA51 plate. Accossato was founded in 1969 in Moncalieri, near Turin.

Natural Terrain and Water Crossings

Natural terrain tracks mix mud, roots, rocks and water in a single lap. The front brake is wet one moment and caked with clay the next. A compound built for these conditions helps the KX450F rider keep control on tricky descents and slippery corners.

After crossing water, drag the front brake lightly for a moment to clear the disc. Back in the paddock, rinse the caliper, check the pads for chipped edges and clean out the slots. Worn pads should be replaced as a pair, and the fluid checked while the caliper is open.

Fitment and Compatibility

For front-brake duty on a KX450F built between 2006 and 2022, Accossato points to plate AGPA51, the same shape used across all its compounds. Those who ride the dirt hard often renew the disc at the same time; Accossato offers DK060 for this model. At the back, the Accossato catalogue shows AGPP106 for bikes from 2006 to 2018. Expect one caliper's worth of pads per box, and compare the new outline with what comes out of your caliper.

Road Approval

We have no ABE or German approval paperwork for AGPA51STMX. It is sold for off-road competition.
