DescriptionThe whole story▼

If your 2019 to 2023 Kawasaki KX450 spends its weekends at hard enduro-style training grounds, sandy coastal tracks or clay circuits after a downpour, the front pad takes a beating. Accossato's AGPA51 front pad in the Off-road sintered mixture is the Italian company's purpose-made dirt compound for this generation of KX450, intended for riders who put in long days in abrasive conditions.

Construction and Material Quality

Accossato presents this as its compound for off-road riders, without further embellishment. What that means for a KX450 of this generation is a pad chosen for a disc that is rarely clean: coated in dust in summer, smeared with clay in spring and sandblasted at coastal venues. Accossato designs all its pads to hold down temperatures and reduce fade while stopping strongly. The STMX material is bonded to the regular AGPA51 plate. Accossato has its roots in off-road sport; the company won an Enduro world title in 1985.

Long Days in the Dirt

A training day on a KX450 can mean six or seven sessions, each one ending with a caliper full of dirt. The front pad has to cope with that repeated abuse while still giving the rider a clear signal through the lever.

Look after the brake between sessions. Knock off clods of mud, let water drain before the next ride, and check the pad faces for chips at the edges. When a session ends in deep water, drag the brake gently for a few metres to dry the disc. At the end of the day, remove the pads if they are packed with sand and clean the slots properly.

Fitment and Compatibility

AGPA51 is listed by Accossato for the front of the Kawasaki KX450 from 2019 to 2023. The 2024 to 2026 models take AGPA29; the rear pad AGPP106 covers 2019 to 2026. The Accossato disc for this bike is DK060. One box is one caliper set; check the outline against your used pads.

Road Approval

We hold no ABE or German approval paperwork for AGPA51STMX. Use it in off-road motorsport.
