The bike might not generate enough power to run the ABS system.
Zero Motorcycles is recalling some 2015 DS, FX, S and SR models for an electrical problem that could disable the antilock brake system. A total of only 96 bikes sold in the U.S. are affected.
The National Highway Traffic Safety Administration reports that the DC-DC converter may not have a sufficient power output margin. In addition to the lights and instruments, the converter powers the ABS by converting the battery’s 89-116 V to 12 V. If the power drain exceeds the capacity, the converter may temporarily shut off.
In cases where the high beam, turn signal and brake light are all on, and ABS is required, the added power draw could overload the converter, temporarily disabling the ABS and turning off the lights.
Zero discovered the issue during development testing on future models. Their dealers will inspect units equipped with these converters and replace them with a stronger component. Contact your local dealer or follow the link to Zero Motorcycles at the beginning of this article for more information,
