The new model has been created with the aim of bridging the gap between the ON-E KIDS 20″ model and the ONE 125cc. A much needed intermediate step for all those young riders who wish to start or maintain their progress on a combustion bike.


The new TRRS ONE 80cc has been specifically designed to meet the needs of the youngest riders between 8 and 16 years of age, looking for a light and manageable package, capable of tackling the most demanding areas.

With this new model TRRS Motorcycles consolidates its range of motorbikes as the most extensive and complete in Trials.

Its new 80cc engine is specifically designed for Trials; a powerful, modern and lightweight engine, with an exhaust optimised for the practice of this modality. Undoubtedly, it is the ideal model to make the leap from electric to combustion units.
