SKF has introduced an innovative StopGo system for two-wheelers that lowers CO2 emissions, and improves fuel economy by an estimated 6-10%, depending on driving conditions. The SKF StopGo design concept allows it to be customized as a ready-to-fit unit which can be assembled quite easily for both 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.
When the vehicle has stopped, for instance at a traffic light, the SKF StopGo senses this and after a predetermined, but programmable short time shuts off the engine. It does restart the engine when the throttle bar is twisted. The SKF StopGo is a three-in-one integrated sensor-bearing solution that performs a bearing function, speed sensing and stop-start function. This unit fits directly 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 sensing in the SKF StopGo provides normal speed data for digital tachometers, which are becoming more preferred than analog systems in new 2-wheeler models. In addition, this new single-unit solution offers advantages of weight saving of up to 60% compared to the many current separate mechanical components needed for the front wheel bearing and speed sensing.
