Warning
Danger of accidents Reduced braking efficiency due to use of non-approved brake linings.
–
Brake linings available from accessory suppliers are often not tested and approved for use on KTM vehicles. The construc-
tion and friction factor of the brake linings and therefore the brake power can differ considerably from the original KTM
brake linings. If brake linings are used that differ from the originals, there is no guarantee that they comply with the origi-
nal license. The vehicle no longer corresponds to the condition at delivery, and the warranty is no longer valid.
