About the ES Bypass — What Still Works
Everything on the dash will work as before, showing correct speed and gear position. Additionally, 4WD, and all temp, oil, neutral, and reverse lights will function normally. However, the gear position indicator will flash, warning the operator it is in bypass manual electric shift mode. This is the only difference in dash operation. The bike will shift up and down in sequence and can be shifted at any throttle position or RPM, unlike the OEM system which requires releasing throttle to shift.
