of biaxial balance shafts . The water and oil pumps are driven by the balancer shafts .
A crank pulsar – with relator teeth spaced at 10 ° intervals – manages misfire detection , important for OBD2 / EURO5 compliance . In addition , for EURO5 Linear Air Flow ( LAF ) sensors in the downpipes give accurate measurement of the air / fuel mixture ratio .
TBW manages engine performance and character , plus Honda Selectable Torque Control ( HSTC ) and Wheelie Control . There are 3 pre-set modes for the rider to choose covering a wide variety of riding conditions and 3 levels of management for Power and Engine Braking , with level 1 delivering the maximum of either parameter . For HSTC and Wheelie Control level 3 provides the highest intervention .
Mode selection is managed from the left-hand switchgear ; an indicator in the instrument display activates when HSTC is working .
URBAN is standard and offers an all-round middle setting of engine power and engine braking .
RAIN reduces engine power and engine braking for extra reassurance on wet or slippery surfaces .
TOUR gives full engine power and standard engine braking , for strong acceleration while carrying a pillion and luggage .
USER 1 and 2 modes offer the ability to customise between the settings for the preferred combination . Once set , the USER setting is automatically stored so there ’ s no need to re-set each time the ignition is turned on . Honda has sold over 200,000 DCT-equipped motorcycles across Europe since the system first appeared as an option on the VFR1200F in 2009 . Testament to its acceptance in the marketplace , since the NT1100 ’ s introduction , 66 % of customer have chosen the DCT option over the manual . The system 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 gears , 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 – crucially – the ability to concentrate more on riding lines , braking and acceleration points .
