In a competition bulletin released Wednesday, MotoAmerica announced that it will allow the use of Supersport 300 World Championship (WSS300) Control Electronic System kits during the 2020 Liqui Moly Junior Cup Championship and that teams can begin using the kit on a limited basis during the event September 7-8 at New Jersey Motorsports Park.

The basic WSS300 kit has a suggested retail price of €2,150 (or $2,396 U.S.) and includes a dashboard, a Mectronik MKE Engine Control Unit (ECU), all the necessary switches, and a wiring harness that can accommodate additional CAN-based devices, like a GPS receiver, a lambda sensor, or a load cell for a quickshifter.

According to the technical bulletin, the new WSS300 electronic system allows for data logging, closed-loop fuel tuning, and more while providing the opportunity for teams to gain entry-level experience tuning electronic systems.

The official supplier of the WSS300 Control Electronic System kit is Solo Engineering (, and kits are available for immediate delivery, according to MotoAmerica.

In the same bulletin, MotoAmerica announced that it will follow the 2019 FIM Supersport 300 World Championship technical rules during the 2020 Junior Cup Championship except for the rules regarding spec tires and fuel. This means that while the FIM Supersport 300 World Championship will only use the WSS300 Control Electronic Systems in 2020, MotoAmerica Junior Cup teams can continue to use reflashed stock ECUs and HM quickshifters/rev limiters or use the new WSS300 kit electronics in 2020.
