The Gas Gas EC 515 FSE is a testament to innovation and reliability, boasting a cutting-edge battery-less fuel-injected engine that has left competitors in its dust. By switching to Kokusan’s high-voltage stator with 16 windings, Gas Gas has created an electric system that not only powers the engine control module but also recharges the lights and starter motor.
The result is an incredibly robust package that can withstand even the toughest riding conditions. With a condenser that charges in just 500 degrees of rotation, the fuel pump springs to life with ease, booting the engine into action at three bar (45psi) pressure.
This sophisticated system also includes a manifold air pressure sensor, allowing the ECM to fine-tune the fuel mixture with unprecedented precision. The end result is a bike that requires no re-trimming once its parameters are downloaded, making it an absolute dream to ride and maintain.
