DescriptionThe whole story▼

Here is Accossato's rear pad for the KTM 450XC-F from 2006 to 2023 in STMX, the Off-road sintered compound. Accossato describes it as its compound for off-road riders, and the rear brake of a cross-country racer is about as off-road as braking gets: it drags through sand whoops, gets dunked in water crossings and bakes in dust. STMX suits riders who enter GNCC-style races, hare scrambles or enduro events and need a rear brake that keeps working when the lap is at its dirtiest.

Key Features

  • STMX compound for the KTM 450XC-F rear brake
  • Fits the 450XC-F from 2006 to 2023
  • Accossato's mix made for off-road riders
  • Made for sand, mud, water crossings and dust
  • Built to resist fading on long descents
  • Two pads in the box for the single rear caliper
  • This rear pad is also available as OR and ST

Construction and Material Quality

STMX is designed by Accossato specifically for off-road use. The company's pads are made to wear slowly, brake strongly and limit the heat they build up, and this rear version brings those qualities to the KTM 450XC-F. The friction material sits on a steel back plate that matches the rear caliper for an even contact patch.

Race Day Rear Brake

At the rear of a 450XC-F in a two-hour race, the pad is fighting abrasive sand and sticky clay. Riders use the pedal constantly to square off turns and control speed on downhills, so a pad that keeps working through all that matters. STMX is meant for that job. For trail training, OR gives a softer pedal, and ST is the all-weather mixed-use option.

Cleaning Between Motos

Wash mud out of the rear caliper with water, not a high-pressure jet aimed at the seals, and check pad thickness after every event. Replace pads in sets, and if the rear disc has picked up deep scoring from trapped grit, look at the disc as well before the next race weekend.

Fitment and Compatibility

This STMX pad fits the rear caliper of the KTM 450XC-F from 2006 to 2023, per Accossato's reference XC-F 450 (2006-2023). One box handles the rear. Accossato lists pad AGPA29 for the front of the same bike, plus the DK017 and DK018 discs.

Road Approval

No German ABE or test certificate is on file with us, so this pad is sold for racing purposes.

Scope of Delivery

Two STMX rear pads for the KTM 450XC-F, packed as one set for one caliper.
