For the second year in a row, the TRRS One RR opts for red on its frame, a colour that now also extends to the anodising of the wheels. Technically, the new model receives interesting novelties at a mechanical and chassis level, as well as the possibility of equipping it with electric start.

Redesigned 2021 TRRS Engine
The engine has been completely redesigned, in order to house the new crankcases cast in aluminum injection, substantially improving the finishes and achieving better behavior at low revs by increasing pre-compression.
The new clutch cover with oil level and fill display, all on the same side, makes it easy to maintain.
With the addition of the temperature sensor in the cylinder head, it is possible to control thermal vibrations and the optimal starting point of the fan, controlled by the new CDI, even better.
The ONE RR has established itself as a benchmark bike, both for the user and for the most demanding rider.
TRRS One RR 125 2021 News
The engine of the RR 125 cc is also significantly improved, its new crankshaft, piston and cylinder head give a considerable increase in power, as well as a reduction in vibrations.
In this case, the final 8-45 gearbox has also been reduced, with which better response and optimal use of the first three gears is achieved.
The electric start of the TRRS
The challenge required modifying the TRRS engine, introducing a new crankcase, new crankshaft and a new magnetic flywheel with its cover.
In its innards, it works with an oil-bathed bearing system. Work has been done to achieve an optimal gear ratio, driven by a powerful 500W MITSUBA SM18 motor together with a Lithium-Ion battery of only 400 grams located behind the headlight.
All this represents a final weight of slightly less than two kilos compared to the model of the same name without electric starter.
