TRRS ONE RRi 2026 – Designed to Lead
TRS Motorcycles renews its flagship model, the ONE RR, an icon of trials, the best seller model of the Brand that represents the essence of TRRS, confirming the continuity of the production of its well-established carburetor version, a model that has proven over the years to be reliable, robust, and with performance fully adapted to the demands of trial riding at both, amateur and professional levels.
The arrival of the new fuel-injection version does not replace, but rather complements the range, allowing each rider to choose between the direct response and mechanical simplicity of the carburetor, or the efficiency and precision offered by the new electronic fuel injection.
In addition, the carburetor model will receive many of the structural and mechanical improvements developed for this generation, further consolidating its performance and dynamic handling:
Available versions
- Electric start – fuel injection: 300 – 250 cc
- Conventional start – fuel injection: 300 – 250 cc
- Electric start carburetion: 300 – 250 cc
- Conventional start carburetion: 300 – 250 – 125 cc
