- New


On TM RACING EN 125, MX 125 from 2005 to 2025, the PROX 37.BD27004 brake disc fits in place of the original part. Gripped by the pads, the brake disc soaks up the heat of every stop. Its design (cut-outs, petal profile) helps clear mud and cool it down.
Measure the thickness with a micrometer every time you change the pads, and replace the disc as soon as it reaches the minimum thickness, or if it's warped or cracked.
ProX Racing Parts has been supplying engine and clutch parts to motocross riders since 1975, from its headquarters near Amsterdam. According to its catalogue, most of its parts are made in Japan, by manufacturers that also produce parts for the Japanese motorcycle makers.
Should the pads be changed along with the disc?
It's strongly recommended: worn pads have taken on the shape of the old disc and won't brake well on a new one.
