HONDA issued a recall on multiple vehicle models

On certain motorcycles, an improperly shaped seal in the brake proportioning control valve could allow brake fluid leakage to occur. With continued use, a leak in the proportioning valve would cause the rear brake to eventually become inoperative. Although the front brake provides most of the braking function, a loss of rear brake force could increase the risk of a crash. Correction: Dealers will replace the brake proportioning valve.
