MTC (MOTORCYCLE TRACTION CONTROL)
As an integral part of the MSC package, MTC (Motorcycle Traction Control) also regulates subject to the angle of lean. It guarantees sporty yet completely controllable propulsion on all surfaces. Its intervention is indicated with a flashing LED in the VDO multi-function display. Depending on the engine mode selected by the rider, MTC permits differing levels of rear-wheel slip. Overall, MTC therefore offers four different characters (plus OFF), selected using the multifunctional switch on the left handlebar grip. Developed in close collaboration with Bosch, it reacts in a matter of milliseconds if the rear wheel begins to rotate too rapidly for the riding conditions. It also makes use of the quick intervention time of the ride-by-wire system to reduce propulsion to a safe level, subject to the angle of lean. Depending on the MTC mode, the EMS (Engine Management System) also makes available a suitable level of power – for example, "only" 100 instead of 150 hp in rain mode.
Four different MTC modes are activated by changing the engine modes:
» Sport: Something for the courageous to try: Allows a respectable and perceptible amount of slippage - drift-feeling all-inclusive!
» Street: Smooth control for comfortable, undisturbed riding with full engine power.
» Rain: Early intervention and minimum slippage in the wet, with engine power reduced to a maximum of 100 hp.
» Offroad: Up to 100 per cent slippage - i.e. double wheel speed - for ambitious offroad use. Have a go at controlled offroad drifts, with engine power reduced to a maximum of 100 hp.
» Off: Those who know better than the MTC can enjoy maximum propulsion at all times, completely to their individual tastes, without electronic assistance.
Engine retarding historically has been accomplished by timing, ie the spark in the combustion cycle. Since the 1190 has a ride by wire system, twisting the throttle does not actually put more gas through a carburetor or fuel injector. Instead there is a throttle position sensor that sends a signal to the computer and provides a corresponding amount of gas to the cylinders. As explained above, in addition to the throttle position sensor the computer is also measuring the lean angle, wheel spin with the motorcycle traction control, and the engine management system (the mode selection). For example when you change the driving mode to off-road, the engine will only produce 100 hp. ie all of these factors essentially retard the engine output to keep the operator safer.
How about we quit debating semantics and go back to enjoying our bikes, :)
So you understand now that ignition in timing is not disrupted now? The system is remarkable in its subtly. The throttle valve adjustment by the computer is next level...
