Official recalls
219V574000 · Visibility
Aug 5, 2019
Harley-Davidson Motor Company (Harley-Davidson) is recalling certain Touring and CVO Touring motorcycles, including 2017-2019 FLHTCU, FLHTCUL, FLHTK ANV, FLHTKL, FLTRU, FLHTK, and 2016-2019 FLHTKSE, FLHTKSE ANV, and FLTRUSE models equipped with a Harley-Davidson Detachable Tour-Pak Luggage Conversion Kit (Part numbers 53000291, 53000291A, and 53000567). The kit did not include replacement rear red reflectors for the ones that are eliminated by installing this kit. As such, these motorcycles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."
Consequence & remedy
Consequence: Without the rear red reflectors, the motorcycle has reduced visibility to other drivers, increasing the risk of a crash.
Remedy: Harley-Davidson has notified owners, and dealers will install the replacement reflectors, free of charge. The recall began August 19, 2019. Owners may contact Harley-Davidson customer service at 1-800-258-2464. Harley-Davidson's number for this recall is 0629.

Consequence & remedy
