Honda E-Clutch is an automatic clutch control system that allows gear shifts without using the clutch lever. When the system is active, the clutch engages automatically during gear changes, but it is still possible to operate the clutch lever when deemed necessary, as the two actuation systems, manual and electronic, are independent. If the system is deactivated, gear changes must always be performed by manually operating the clutch lever.
The system differs from a dual-clutch transmission because it acts solely on clutch control, lacking automated gear shifting control like the DCT system found in high-end Honda models. This design choice keeps the transmission and clutch mechanisms simple and lightweight, allowing the rider to manage gear shifts as on a traditional motorcycle.
The system is powered by two electric motors and a set of gears located inside the right engine cover, controlled by a dedicated control unit (MCU) that manages the clutch based on data received from the vehicle's control unit (ECU).
Compared to a quick shifter system, it offers the advantage of smoother and quicker gear changes, reducing rider fatigue during road riding and minimizing abrupt vehicle movements induced by gear changes during spirited track riding.
The system is already standard on the new CB650R and CBR650R models.
