The world can be a messy place—especially the road surface directly ahead of your motorcycle. Riders should always be on the lookout for contamination and foreign substances in the roadway. To provide a bit of assurance in an unsure world, Honda has incorporated Traction Control systems on some of its motorcycles, notably the current CTX1300 Deluxe and VFR1200F.
Traction Control systems limit rear-wheel slippage during acceleration on low-traction road surfaces and also during hard acceleration. The Traction Control system performs this function by constantly monitoring the speeds of the front and rear wheels via the wheel speed sensors incorporated into the Anti-Lock Braking System (ABS). The system also factors in data from various engine parameters, plus throttle position. A potential loss of traction is calculated when the rear wheel begins to rotate significantly faster than the front. When the speed variance between the front and rear wheels grows large enough to indicate an imminent loss of traction, the system regulates torque application automatically by reducing fuel delivery to the engine. This ensures a seamless, unobtrusive modulation of power delivery in low-traction circumstances.
