## What is wrong

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 can happen

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


## The remedy

Dealers will replace the return spring, free of charge.  Owner notification letters were mailed May 21, 2021.  Owners may contact KTM customer service at 1\-888\-985\-6090.  KTM's number for this recall is KTM2106.
