Yamaha is recalling 2014 YZF-R6 sportbikes because of a manufacturing error affecting both the front and rear wheels that may result in a loss of tire pressure. The recall is limited to just 28 units in the U.S., but if you’re one of those few unlucky owners, you are advised to stop riding until a repair is completed.
According to documents released by the National Highway Traffic Safety Administration, the aluminum wheels did not undergo the proper cooling process during manufacture and may not meet the required hardness specifications. This may result in the wheel bearing moving from its proper position, loosening the wheel and potentially causing deformation which could allow air to leak from the tire.
Normally, the wheels would be submerged in a water bath during production. For the batch of wheels affected by the recall campaign, the water level in the bath wasn’t high enough, thus providing insufficient cooling. Yamaha Motor U.S.A. was informed of the problem by its parent company, Yamaha Motor Co. on Oct. 6 after a quality control review of exported models.
Yamaha dealers will replace both the front and rear wheel assemblies on recalled units.
