The wheel speed sensors on the ABS rings at both ends will record the wheel speed of the front and the rear wheel and then send this data to the ECU. The ECU is short for Engine Control Unit or Electronic Control Unit which takes care of the fuelling and ignition of the engine based on the data it gets from various sensors in the bike.
The first and most common way of bringing the rear tyre under traction is by cutting the fuel supply to the engine. As the fuel supply cuts off the cylinder will miss fire and the power will drop suddenly and this drops the amount of torque channelling to the rear tyre. As the power drops, the rear tyre slows down and this happens until the speed of the rear is matched with the front wheel and the rear tyre get its traction back.
This way of controlling traction is conventional and is jerky and not so smooth to have in the premium bikes. On the other hand, if the bike is equipped with ride-by-wire technology, the traction control becomes much smoother. In this technology, there is no conventional cable running down from the throttle to the throttle valves rather a sensor reads the throttle position and then sends a signal to a servo motor which open and closes the throttle valves.
When the rear tyre loses traction, the ECU simply takes control of the throttle valves and closes them reducing the supply of air-fuel mixture to the engine which in turn drops the power and the rear tyre slows down and traction is gained back.

Apart from this, you can receive up to 12 months of warranty on the used two wheelers at Bikes There are two major types of traction control systems available on motorcycles — Reactive and Predictive.
As the names suggest, the reactive traction control system acts when the wheel spins and tries to bring back the traction under the tyre. The reactive traction control is used for affordable bikes and usually utilises the fuel-cutting method to reduce the power supply and control the wheel spin. This type of system does not need any advance sensors and devices apart from ABS rings which are available in all the bikes above cc and ECU which is also present in all the bikes as the BS6 emission norms forced manufacturers to add electronic fuel injection systems on the bikes.
Moving on to the predictive traction control system, this one is definitely an expensive piece of technology. Here, the motorcycle must have ride-by-wire technology so that ECU can gain control over the throttle and vary the flow of air-fuel mixture to get to a sweet spot of maintaining the traction. Not only this, the reactive TCS employs a series of advanced sensors like bank-angle sensors, inertial measurement unit, vehicle speed sensor, wheel speed sensors and a lot more.
All these sensors work together to collect data in real time which help ECU to analyses and make the changes before the motorcycle slips due to low traction or the bike tends to drift under abrupt power delivery. The predictive system is much smoother and safer than the reactive system of controlling traction. You will find the predictive traction control on all the premium motorcycles on sale in India.
Traction control is an important technology which is required when your bike has a lot of power on offer and especially if you are looking for buy an off-roading machine. Traction control is more important on the off-road terrains as it is difficult to find the traction for the armature riders.
On the sports bike and superbikes, the power delivery has to be abrupt on the race track on every occasion the rider exits the corner. As a learning rider or beginner riders do not have complete control over the traction and the throttle, the traction control really helps a lot. One more thing one should understand is that all the superbikes comes with multi-level traction control system with an option to completely switch it off. This is given so that riders can learn to launch bikes from rest with minimum interference from the traction control system and level up their skill sets.
This will motivate to you sell your used two wheeler at Bikes24 and make way for a new ride. BIKES24 is a new platform where you can sell your old bikes and scooters in under 2 hours and get the amount transferred directly to your bank account.
These technologies work together to keep you on your bike. They got one thing partially right: ABS does stop wheel lock. To assess this part of the question, we need to know what they mean by those terms.
In cars, traction control was an early technology that simply cut engine power when the wheels started spinning. Stability control is a lot more elaborate and involves sensors that detect pitch, roll and yaw, controlling it with a variety of measures that include throttle, brakes and even some steering input.
So VicRoads firstly need to get their terms right. As it is, the mention of stability control is simply confusing. Also, traction control would not activate under braking unless you are accelerating at the same time. The idea of traction control is to prevent rear-wheel spin from too much power for the road surface by cutting engine power. It helps to prevent power slides, but also wheelies and burnouts!
As a motorcycle journalist, I have experienced traction control on many different motorcycles. On one early incarnation, it hesitated in identifying the slip and then abruptly stopped the engine power, nearly throwing me over the high side. However, traction control has improved dramatically and many modern bikes now offer varied controls for varied conditions.
This allows the rider to use power to turn the bike by sliding the tail to a certain degree before intervention. Traction control will also help prevent slides on wet tarmac or bitumen roads with corrugations or slippery debris.
But it is wrong to think that traction control will prevent crashes. The problem is that if you do crash on a bike with traction control, it will most likely be at higher speeds than if you had no traction control! Having traction control on your bike may also provide a false sense of confidence that makes riders careless with throttle use. This is the safest way for the engine to reduce the power.
Secondly, it can be achieved by a modern-day ride by wire technology. In this, the system adjusts the throttle position electronically. This system potentially limits the power even if you rev harder. So, it can also avoid the human error if any. Various pre-configured riding modes limit the throttle response. This way has some limitation because the response, many times, is not so quick enough. The traction control setup can be different according to the weather condition or according the rider level.
Traction control for rain condition is made to compensate the low level of grip. For example an expert rider can use the sliding of rear tyre to turn the bike when coming out of the corners. A street rider instead need more support because the level of grip of asphalt can change quickly for example when you meet dust or wet patch in mountain road. Many traction control systems like our GRIPONE should offer a remote controls like buttons to change the sensitive of system making in real time.
You can simply rely on all these goodies, as such systems are designed to help you.
