DescriptionThe whole story▼

Engine braking on a Husqvarna FC 450 is strong, and in slick conditions it can combine with the rear brake to lock the wheel before the rider notices. A rear pad that responds the same way in rain, heat and cold makes that balance easier to manage. Accossato's AGPP80 in the Sintered (ST) compound is catalogued for the FC 450 from 2014 to 2026. The company says it keeps a high and constant grip level whatever the temperature, and grips well when wet. It is aimed at riders who ride every month of the year.

Key Features

  • Sintered (ST) rear brake pads for the Husqvarna FC 450, 2014 to 2026
  • Constant grip in heat and cold, according to Accossato
  • Good bite when the disc is wet
  • Helps balance engine braking and pedal pressure on slick ground
  • For all-year riders and wet-weather racers
  • Two pads, one set for one caliper
  • No German ABE; supplied for motorsport

Construction and Material Quality

The ST variant of the AGPP80 plate is designed for stability. Accossato states that grip stays high and constant at low and high temperatures and that the mix works reliably on a wet disc. At the rear of a big four-stroke, where engine braking already slows the wheel, a stable response makes it easier to add just enough pedal pressure without locking.

Engine Drag and the Rear Pedal

When the rider shuts the throttle on an FC 450, the engine already slows the rear wheel hard. On a slippery surface, adding too much rear brake on top of that can lock the tyre. A predictable pad gives the rider a consistent reference, so they learn exactly how much pressure the bike tolerates in each condition. Over a wet season, that consistency builds confidence. Maintenance counts too: wash the caliper after every muddy ride, check pad thickness regularly and keep the brake fluid at the right level. Clean the pistons before pushing them back when changing pads.

Fitment and Compatibility

This rear pad is listed by Accossato for the Husqvarna FC 450 from 2014 to 2026. The front pad for the same machine is the AGPA29, and DK017 and DK018 discs are catalogued for it. The AGPP80 plate also comes in OR and STMX. One rear caliper means one box.

Road Approval

These pads are not covered by any ABE or test mark we have received. We sell them for competition purposes.

Scope of Delivery

One box containing a pair of AGPP80ST rear pads.
