Motorcycle has exhibited unstable handling behavior since delivery. The defect is specifically a weaving and wobbling oscillation that occurs when the motorcycle is upright and traveling in a straight line, as if the bike is constantly riding on rippled or uneven pavement even on smooth road surfaces. The rear of the motorcycle feels disconnected from the chassis, with the rear tire feeling as though it is not tracking with the front. The instability is present at all speeds but becomes pronounced and consistent at approximately 40 mph and above. Critically, the defect occurs only when the motorcycle is upright. The instability is not present during cornering or while braking — the bike feels stable when leaned over or under deceleration. The weaving and wobbling are confined to straight-line, upright riding. The defect is present: •In all ride modes (Road, Rain, Dynamic, Dynamic Pro) •Both loaded and unloaded •With top case and panniers fitted — no difference observed •On and off throttle •On smooth pavement with no road-surface contribution The instability is not consistent with normal motorcycle dynamics and is not corrected by tire pressure adjustment, rider input, or ride mode selection. Dealer interaction: Original selling dealer was non-responsive to handling complaints. Motorcycle is scheduled for diagnostic evaluation at a second BMW Motorrad dealership on June 1, 2026. BMW Motorrad USA customer relations case has been opened [case number if available]. Safety concern: Sustained weaving and wobbling instability at highway speeds while traveling upright on a motorcycle creates a significant crash risk, particularly during straight-line highway riding, lane changes, or in crosswinds. The defect has been present since delivery and has not been resolved through normal service channels. No crash, injury, or fire has occurred to date. Report is filed to document a safety-relevant defect present since new on a current-production R 1300 platform motorcycl
