An official CAA Japan notice concerns Motorcycles (Harley-Davidson Low Rider ST and 7 other models) - Repair. Defective rear shock adjuster mounting bracket. ■ Defective part (part name): Rear shock adjuster mounting bracket. ■ Condition and cause of the structure, equipment or performance deemed noncompliant with standards: Due to insufficient assessment of the strength of the rear shock adjuster mounting bracket, vehicle vibration at high engine speeds may cause the bracket to resonate and develop cracks. These cracks may progress and cause the bracket to break, allowing the rear shock adjuster to fall off and contact the rear tire. This may wear away the rear tire tread and reduce tire pressure, potentially causing loss of balance while riding and a fall. Published 2025-11-21.
What to do now
(Recall notification number) 外-4100 ■ Corrective measures: Add a crossmember caddy to the rear shock adjuster on all vehicles. Also inspect the rear shock adjuster bracket and replace it with a new one if damaged.
