Yamaha is recalling the 2015 SMax because of a problem that can cause the speedometer to stop working. The recall affects 2,640 scooters in the U.S. The SMax XC155 is also sold in other markets (where it may known as the Majesty S). A similar recall has been announced in Japan.
According to the document issued by the National Highway Traffic Safety Administration, the speed sensor wire may not have sufficient warranties and front wheels may be unstable or act through the front suspension. This can lead to fatigue and breakage of the sensor leads, preventing the vehicle speed from transmitting the speedometer.
Yamaha Motor Corp. U.S.A. first received word of the problem on Dec. 2 from Yamaha Taiwan following a quality control review on another model that uses a similar design.
Dealers will replace the speed sensor assembly on recalled units with a redesigned part that uses two retaining clips to hold it in position. The original speed sensor assembly only used one retaining clip.
