The Trrs One RR 300cc 2027 with carburettor combines electric start and kick-start. This configuration provides both starting systems alongside the single-cylinder two-stroke engine, fuelled by a Keihin PWK 28 carburettor. Its commercial designation of 300cc corresponds to an actual displacement of 294.1 cm³.
The electric-start version features a Tech fork with 39 mm aluminium stanchions and a two-way Tech TJ3 GP rear shock. Both offer compression, rebound and spring preload adjustment. The specification is completed by a TRS hydraulic diaphragm clutch, five-speed gearbox and Galfer brakes with Braktec calipers.
For 2027, the ONE RR receives a new colour scheme and graphics, retaining the engine introduced the previous season. Its dry weight is 68.5 kg, corresponding to the carburettor and electric-start configuration.

Differences between the ONE RR 300cc with electric start and the kick-start version
Within the carburettor-equipped versions, the main differences concern the starting system, fork material and weight:
| Feature | Electric start | Kick-start |
|---|

|---|
| Fork | Tech with 39 mm aluminium stanchions | Tech with 39 mm steel stanchions |
|---|

Who is it designed for?
For trials riders looking for the 300cc model with a carburettor and electric start, while retaining the kick-start. This choice keeps the Keihin PWK 28 fuel system and provides two ways of starting the engine.
The adjustable suspension allows settings to be adapted to the rider and terrain. Our team can advise you on this configuration and compare it with the kick-start or fuel-injected alternatives within the range.
