This new system can be customised as a ready-to-fit unit which can be assembled by OEMs and as retrofit for a wide range of makes of two wheelers.

SKF is set to be the first supplier of stop-start technology for two-wheelers. The component major has introduced StopGo –an automatic stop-start system for motorcycles and scooters. The company says the new solution lowers CO2 emissions, and improves fuel economy by an estimated 6 to 10 percent, depending on driving conditions.

Comparing the new solution to a vehicle platform, Harsha Kadam, Director – Global, Two Wheeler business, SKF India told our sister-magazine Autocar Professional that it can be further developed to offer ABS (anti-lock braking system) and perhaps even tyre pressure monitoring for the two-wheeler.

The StopGo can be customised as a ready-to-fit unit which can be assembled by OEMs and as a retrofit for a wide range of makes of two wheelers already on the road. The system can be applied to a wide variety of motorcycles, independent of engine size. The technology has been developed by SKF India with input from the mechatronics division of SKF France.

When the vehicle stops at traffic the StopGo system shuts off the engine after a predetermined, but programmable time. It restarts the engine when the throttle is turned.

SKF StopGo is a three-in-one integrated sensor-bearing solution that performs a bearing function, speed sensing and stop-start function. The unit fits into the hub of the front wheel, like a standard bearing, and is connected by a plug-and-play connector to a mating connector attached to the engine stop-start electronics.

As well as sensing the speed for the stop-start function, the speed sensor in the SKF StopGo provides normal speed data for digital tachometers, which are becoming more preferred than analog systems in new 2-wheeler models. SKF says the new solution offers weight saving of up to 60 percent compared to the many current separate mechanical components needed for the front wheel bearing and speed sensing.

SKF has conducted trials in premium bikes like TVS Apache, Bajaj Pulsar and Hero Karizma. Kadam says that work is on to offer the StopGo solution also to entry level bikes which do not have an ECU. The first StopGo fitted bike is expected to hit the road this year.

SKF all set to launch bolt-on start-stop system for two wheelers called the stopgo

The product is now ready for a launch in the Indian two wheeler market. Also, more details have been revealed about the nature of the StopGo start-stop system from SKF, which can be fitted both at the manufacturers end as well as retro fitted onto existing vehicles. Needless to say, the minimum requirement for the SKF StopGO system will be the presence of an electric start option on the two wheeler, without which the system cannot work.

Coming to the StopGo system in itself, SKF has designed the unit to be mounted onto the hub of a two wheeler’s front wheel. This system will perform three operations by means of a sensor. The three functions are, bearing function, speed sensing and stop-start function. The start-stop system will sense the two wheeler coming to a rest through the sensor. After a preset time of say about 5 seconds, the system will turn off the engine. When the rider wants to move ahead, all he or she needs to do is to twist the throttle of the two wheeler.

The system will seamlessly start the engine and the rider can move forward. The whole idea around the start-stop system is that it will minimize the wastage of fuel while idling at traffic lights and other stop-go traffic conditions. Used in urban cities, one can expect a fuel saving of about 5%, which should recoup the cost of the system if the SKF StopGo start-stop kit is priced well. Apart from saving fuel, the other big advantage of the start-stop system is to cut down on carbon dioxide emissions. Given the threat of global warming and its adverse effects, automakers across the world are working on minimizing CO2 emissions.

SKF has put out some interesting statistics about how much CO2 emissions their StopGo system can cut down on. SKF claims that the StopGo system reduces CO2 emissions by 5 grams/kilometer, which means that an annual running of about 7875 km will reduce CO2 emissions by about 36 kilograms per year from every two wheeler. SKF estimates that if 1 in 3 two wheelers around the world adopt this system, the annual CO2 emissions can be cut down by about 36,000 tonnes, a figure which is a mammoth number indeed. All in all, the SKF StopGo system is a welcome addition to the world of two wheelers and we hope that the bearings major manages to price it competitively so that the use of this system becomes widespread.

This is a interesting piece of information [clap], but my doubt is that just imagine the traffic situation in our cities where in bumper to bumper traffic, we stop and go just for a while many be 10 seconds and it may happen some 100 times, so all these 100 times it will switch off and switch on the engine ?? if so what will be the engines story for frequent switch of and switch on [confused] and what about this units story works so many times within the fraction of few minutes?? will it be practical on our roads, I think you know what I am talking about the road traffic, which you also know this kind of traffic near silk board,KG road before mysore bank and somany places

I guess they will probably add a switch to activate or de-activate this system just like the Scorpio Micro Hybrid system

India could be the first ever market for bikes to receive start-stop button tech. Quoting an excerpt from Overdrive.in.
Director of TE Connectivity India S Vishwanath said, “We cannot disclose the detail of our customer right now, but we are working with a Tier-1 supplier for designing components for Start-Stop for two-wheelers in India. The tier–1 is a multinational company and we are in an advance stage of discussion. If everything goes well, in a few months we will see it in the market. Initially it will be retrofitted. We are in the design stage and will start the supply in the next three months. But I think it is just a question of time. I hope very soon even the two-wheeler OEMs will take it up.”

Some of the leading customers of TE Connectivity’s Start-Stop tech include German OEMs such as BMW, Audi and Mercedes. While the technology will be more adaptable to the gearless scooter/two-wheeler rather than motorbikes, the Tier-1 company in question is said to be putting more thrust on the motorbike segment because of its sheer market volume. In the geared two-wheelers, the Start-Stop function can work only in neutral. The sensor will not function in a geared position since it cannot start without pressing of clutch.

Although it is initially being launched in the aftermarket, but some of the OEMs have already shown interest. So far, there is no such system available for two-wheelers anywhere in the world. The Start-Stop technology is very popular in cars in the European markets and almost all of them have this option. It is, however, yet to take off in India due to the cost involved. This system will have higher acceptability among the Indian two-wheeler owners because of their known obsession over fuel-efficiency. But while the technology improves the fuel-efficiency, the pricing will be the key.

According to TE Connectivity, the pricing of the system should be fixed keeping in mind the mass segment bike-owners (starting 100cc). On the other hand, the increasing price of fuel will also encourage the bikers to make a one-time investment to reduce the overall operating cost of the vehicle.

“It works very well with automatic transmission, but for a gear transmission it has to be in the neutral position. The system will be more adoptable for gearless scooters. The OEMs are also showing interest in it. This would be probably the first time that a Start–Stop option for two-wheelers will be available,” S Vishwanath said.

It sounds interesting and my bike (Karizma ZMR) can adopt it very well but only issue who cares to put the bike in neutral. It's troublesome to find neutral at each signal stop.
