The lightweight 125cc liquid-cooled engine is built to deliver smooth, progressive power and torque, allowing you to deliver lap after lap without fatigue, cutting away tenths at a time. Developed over the last 3-years the engine mapping has been finely balanced to allow both low speed control when in the city and dynamic throttle response when pushing the pace.

Power and control picture


The GPX features a digital instrument panel with crisp illumination of only the most important data to help you conquer any road or circuit, day or night. Glove friendly touch buttons allow you to quickly make changes to the display information on the fly whether tucked in or riding the cool down lap.

Clear and intuitive display picture


Everything about the GPXs bodywork has been designed and refined to deliver both class-leading aerodynamics as well as a truly race inspired style. The ergonomic triangle of handlebars-seat-footpegs has been optimised to suit both taller and shorter riders, offering a riding position which is equally as comfortable as it is commanding. The tubular steel frame paired with upside-down front suspension & linkage-driven rear mono-shock keeps the handling light and predictable as well as offering superb high-speed comfort. The consequence? Less fatigue, faster laps.
