also requesting the same product. However, the supplied motors
started burning out aſter more mileage and time was applied on the product, which had the potential to negatively impact teams’ racing performance. Furthermore, the addition of the extra teams that had adopted the actuation systems made testing and altering the setup more difficult and time consuming for Bike Sport Developments.
Problem solving at full throttle “When the motors began to burn out, the situation was very stressful, especially given the importance of engine reliability,” said Mick. “However, faced with these challenges, EMS really came into their own. Te team worked alongside FAULHABER to identify a list of potential causes for the motor failures, which we were then able to systematically test and rule out one by one.” Initially, EMS suggested altering the bike’s ECU system, which
could have been overloading the motor. However, since the electronic soſtware was supplied by another partner of Bike Sport Developments’ client and not directly through them, this proved unfeasible. Bike Sport Developments eventually opted for a modular plugin
inductor to sit between the bike’s ECU and the throttle actuator, smoothing the current supply. “Troughout the fault testing process, EMS was always on
hand to support us. Te team’s suggestions showed not only their willingness to help, but also their extensive product and application knowledge,” said Mick. “Aſter disconnecting our motor from the wiring of the bike and
fitting the module between the two components, the issues we’d previously experienced with overheating and burning out stopped pretty much instantly.”
Racing success Te project is now in its third year, with the last 18 months being free of motor faults. In this year’s Daytona 200, six of the top ten placing bikes were Suzuki GSX-R750s, which use the throttle actuators supplied by EMS and Bike Sport developments. During the race, the bikes achieved 100 per cent throttle control reliability. Te actuator solution has not only brought success on the track,
but also resulted in higher sales for Bike Sport Developments. Despite initially predicting to receive less than ten orders, the business has now sold over 70 of the actuation systems, with customers including teams in England, Germany, the Netherlands and France.
