Zero Motorcycles Inc. has recalled certain model 2017 S, DS, and FXS motorcycles. The reason for the action is Anti-Lock Braking System (ABS) Hydraulic Control Unit (HCU) may have the wrong vehicle model information, possibly causing the ABS to function improperly.
If a braking event triggers the ABS, the incorrect ABS profile on these subject motorcycles will not behave as intended, which could increase the risk of a crash.
On Feb. 22, 2017, during development testing of a future model, a Zero test rider commented that “the front ABS seemed to come on a bit earlier than normal.” This was followed by similar comments on the same motorcycle made by two additional test riders on February 24 and 28.
On March 1, 2017, it was determined that this test motorcycle had been configured with the incorrect ABS profile. When looking into the reason behind this, it was discovered that due to errors in programming by both the supplier of the HCU (Robert Bosch LLC) and Zero Motorcycles production, the suspect population noted above was configured with the incorrect ABS profile.
