The short answer

NHTSA received KTM North America, Inc.’s report on Apr 30, 2021. Copied from NHTSA on Oct 28, 2026.

Every line below is in NHTSA’s own words, with its source beside it.

What’s wrong with it?

A front brake with reduced functionality may increase the distance required to stop as well as the risk of a crash or injury.

KTM North America, Inc.

(KTM) is recalling certain 2019-2020 KTM 790 Adventure and 790 Adventure R, and 2020 KTM 790 Adventure R Rally motorcycles.

The front brake master cylinder piston return spring may be too weak to return the brake piston to its original position, reducing the functionality of the front brake.

What the record doesn’t say

  • NHTSA’s recall file doesn’t say whether anyone was hurt. Owners’ complaints are counted on each vehicle’s page.
  • Whether one vehicle or seat has been fixed: only its maker, or NHTSA’s lookup with a VIN, can say.
  • How many have been returned or fixed isn’t in the notice.
