Honda announces fully automatic transmission for large-displacement motorcycles

If you thought that automatic transmission belonged to small displacement scooters and cars, think again! Honda Motors has announced that it has developed a Dual Clutch Transmission, the world’s first fully automatic motorcycle dual clutch transmission for large-displacement motorcycles.

According to Honda, new Dual Clutch Transmission provides riders sporty riding enjoyment with easy operation, while its superior transmission efficiency delivers fuel economy equal to or better than a conventional manual transmission. A new VFR large-displacement sport bike equipped with the new transmission will be released in Europe and North America in 2010, with sales to commence in Japan at a later date.

This world’s first motorcycle dual clutch transmission features a light, compact design that allows it to be combined with existing engines without substantial layout modification.

Further, the new transmission delivers the precise acceleration control riders require thanks to electronic control technology that helps ensure smooth, seamless gear changes. In order to respond to rider demands in a broad range of situations, the transmission is equipped with three operating modes, two full-auto modes (D-mode for regular operation and S-mode for sporty riding); and a 6-speed manual mode, which delivers the same shift feel as a manual transmission. Honda intends to gradually expand the deployment of the new transmission to more and more of its large-displacement motorcycles, particularly sports models destined for use in developed countries.

Key Features of Dual Clutch Transmission

The new transmission features a dual clutch transmission configuration in which independent clutches are employed for the odd gears (1st, 3rd, 5th) and the even gears (2nd, 4th, 6th), respectively. The two clutches operate alternately to effect gear changes. For example, when changing from 1st to 2nd gear, the computer detects the up-shift and engages 2nd gear, then releases the 1st-gear clutch while engaging the 2nd-gear clutch to achieve a seamless gear change. While some dual-clutch transmissions tend to be bulky, the new system employs original technologies such as dual input shafts, exclusive in-line clutch design, and concentration of hydraulic circuitry beneath the engine cover to achieve a compact design. Compactness and lightness is further enhanced through the use of a simple shift mechanism design based on that of a conventional motorcycle shift drum. Optimized shift scheduling achieves fuel economy equal to or better than that of a fully manual transmission, enabling Dual Clutch Transmission to deliver both sporty riding and environmental performance combined.

  4. hi i would 2 knew that auto transmission motor cycle available in INDIA am a handy cap of my left leg but i fond of bike & i also prefer low height bike what it is possible in future

  5. Dharmesh, unfortunately, as of now there is no such motorcycle available in India. You do have the option of going in for older Enfields, which came with gears on the right hand side. However then you will either have to rely upon only the front brake or get combined braking system fixed, where by both the front and rear brake are operated by the front brake lever (would basically be a jugad).
