In Europe, the CL500 and Rebel 500 are particularly popular, both of which use the well-known 471 cm³ parallel twin engine that is also used in the NX500, CBR500R, and CB500 Hornet. It has not yet been confirmed whether these models will also be equipped with E-Clutch in the future. However, the expansion to the smaller CL250 and Rebel 250 models shows that Honda is apparently planning to establish the system in other series.
How E-Clutch works
Honda’s E-Clutch allows the rider to start, change gears, and stop without having to operate the clutch lever. The gear lever still needs to be operated – unlike fully automatic transmissions such as Honda’s DCT (Dual Clutch Transmission), which can also change gears automatically. The E-Clutch system continues to rely on a conventional multi-disc clutch, but this is supported by electromechanical actuators.
One advantage of the E-Clutch is the significantly reduced interruption in traction when changing gears, which should result in noticeably smoother driving. The clutch engagement can even be customized for smooth (SOFT), medium (MEDIUM), or hard (HARD) gear changes—both when shifting up and down.
Target group and market potential
With the E-Clutch, Honda is particularly targeting motorcyclists who are considering switching from automatic scooters to motorcycles or who generally value ease of use. The technology is also seen as a bridge between fully automated transmissions and classic clutch systems. The aim is to attract new target groups to motorcycling by lowering the barrier to entry.
While Honda is considered a pioneer in this development, other manufacturers are pursuing similar approaches. Yamaha offers the Y-AMT system, BMW relies on the Automated Shift Assistant, KTM has introduced the AMT (Automated Manual Transmission), and Ducati says it is working on an automated transmission system.
Differences from centrifugal clutches
It is important to emphasize that the Honda E-Clutch differs fundamentally from the centrifugal clutch found on many small-displacement motorcycles and mopeds. While centrifugal clutches allow the motorcycle to start without operating the clutch, the E-Clutch still uses the classic multi-disc clutch – but with intelligent control.
Outlook: Further models conceivable
Even though the CL250 and Rebel 250 are currently only available with E-Clutch in selected markets, the technology could reach other models in the future. It remains to be seen whether the popular 471 cm³ twin-cylinder engine from the CL500, Rebel 500, NX500, CBR500R, and CB500 Hornet will soon be combined with E-Clutch. However, the development of E-Clutch is likely to further motivate other manufacturers to bring their own systems to series production.
