Honda has sold over 240,000 DCT-equipped motorcycles across Europe since the system first appeared as an option on the VFR1200F in 2009. For the CMX1100 Rebel, since its introduction 57% of owners have chosen the DCT option.
DCT delivers consistent, seamless gear changes and very quickly becomes second nature in use. It uses two clutches: one for start-up and 1st, 3rd and 5th, the other for 2nd, 4th and 6th, with the mainshaft for each clutch located inside the other for compact packaging.
Each clutch is independently controlled by its own electro-hydraulic circuit. When a gear change occurs, the system pre-selects the target gear using the clutch not currently in use. The first clutch is then electronically disengaged as, simultaneously, the second clutch engages.
The result is a consistent, fast and seamless gear change. Furthermore, as the twin clutches transfer drive from one gear to the next with minimal interruption of the drive to the rear wheel, any gear change shock and pitching of the machine is minimised, making the change feel direct as well as smooth. Extra benefits include durability (as the gears cannot be damaged by missing a gear) impossibility of stalling, low stress urban riding, reduced rider fatigue and extra ‘brain space’ to concentrate on pure riding aspects such as riding line, cornering, braking and acceleration points.
The DCT system offers two distinct riding approaches – the Automatic settings, with pre-programmed shift patterns which constantly read vehicle speed, gear selected and engine rpm to decide when a shift should occur, and the Manual Transmission setting for gear changes using the paddle-shift style triggers on the left handlebar.
Through TBW control, the DCT shift patterns are linked with the 3 riding modes.
In STANDARD riding mode, the DCT shift pattern offers a balance between high-gear, low-speed cruising and low-gear, full-throttle excitement.
RAIN selects higher gears more quickly for a super-smooth ride.
SPORT delivers higher-rpm and lower gears, holds onto revs for longer before upshifts, and downshifting at higher rpms for more engine braking effect.
The USER option also allows the rider to adopt any of the three DCT shift patterns in any riding mode according to preference.
