    Sinnis GPX 125

Sinnis GPX 125 | FROM £3,699.00*

The 2022 Sinnis GPX 125 takes its spot on the starting grid, poised for the lights to go out. Are you ready to feel like a true racer and be introduced to the excitement, adrenaline and performance of supersports bike riding?


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.


The powerful LED headlights have been moved down into the side pods of the fairing to de-clutter the front of the bike and give a full-on race vibe. The LED running lights focus the front end, while the integrated tail-light will give your rivals something to watch as you clip the apex and head towards the podium.

*Registration fee's and extra charges may apply, please contact us about this model for more information.
