Enjoy the performance of a manual transmission with the convenience of an automatic.
Honda introduces the world's first dual-clutch transmission for use in a motorcycle.
1. What is the Dual Clutch Transmission?
Dual Clutch Transmission is a motorcycle transmission that automates clutch and shift operation while retaining the essential structure and direct acceleration feel of a manual transmission. Since clutch operation is not required, the rider is free to focus on operating the throttle and brakes. Moreover, Dual Clutch Transmission offers acceleration and shifting while minimizing the power gaps that occur during shifting with a manual transmission.
As the name suggests, Dual Clutch Transmission features two clutches: one for off-the-line acceleration and 1st, 3rd and 5th gears, and one for 2nd, 4th and 6th gears. The use of this technology in a motorcycle is a world’s first.
Dual Clutch Transmission offers AT Mode for automatic shifting and MT Mode for rider-controlled shifting. In addition, AT Mode comprises D Mode for daily riding and S Mode for sporty riding.
2. Shift modes to match the rider’s mood
Thanks to its ability to respond to riding conditions, the system is able automatically to return to AT Mode from MT as needed and to maintain a selected gear during cornering. By monitoring riding conditions based on vehicle speed, engine rpm and other factors, the system is able to select gears with extreme precision.
The rider may perform shifting with the standard handlebar switch or with the optionally available foot pedal.
Note: Not available with the Integra or the pre-2012MY VFR1200F
3. Internal configuration of the Dual Clutch Transmission
Let’s take a look at how Dual Clutch Transmission automatically operates the clutch and performs shifts during acceleration and deceleration in the VFR1200F.
4. How Dual Clutch Transmission automatically shifts gears
With a regular manual transmission, the rider changes gears with the left shift pedal. This action rotates the shift drum, and shift forks slide the gears into position. In Dual Clutch Transmission, the shift control motor performs this same function, turning a gear shift spindle. (With the optionally available shift pedal, the mechanism is identical.)
5. Making Dual Clutch Transmission accessible to even more riders
Dual Clutch Transmission lets the rider enjoy the riding feel of a manual without the need for shifting or clutch operation. To make this system accessible to as many riders as possible, Honda offers it on a variety of different motorcycles, optimizing its structure to match the engine and model characteristics of each bike.
For example, the NC700S, NC700X*and Integra are New Midsize Series motorcycles that feature the same frame and engine, yet the Integra has floor-like steps not found on the other two models. To harmonize this particular feature with Dual Clutch Transmission, Honda optimized the clutch and crankshaft layout shared by all three members of the series.
*In 2014 to reflect an increased engine displacement, the NC700S and NC700X were renamed NC750S and NC750X respectively.
