TRRS One R 2023

TRS Motorcycles
presents the new TRRS One R 2023, the model that represents the brand’s mid-range, with first-class performance and more affordable than the One RR.

The TRRS One R was born to establish a middle ground between the standard One, with R16V shock and Dell’Orto carburetor, and the One RR. It is more similar to the latter, as it is equipped with a Keihin carburetor and a Reiger single-way shock (instead of a two-way).

The new 2023 TRRS One R is available in both standard start (125, 250, 280 and 300cc) and electric start (250, 280 and 300cc).

At the chassis level, it receives a crankcase protector with a wider groove that increases protection at the bottom of the chassis. Machined and anodized steering plates in the same color.

We also found a new electrical installation for the temperature sensor, increasing accuracy and reliability.

The CDI is also new and features a temperature sensor reader. By incorporating the temperature sensor in the cylinder head, it is possible to better control thermal variations and the optimal starting point of the fan.

New in displacements 250-280-300

The aluminium injection crankcases have received an update, which increases manufacturing precision and reduces stresses.

The filler cap changes to anodized in red, as well as the boot lever cinch bushing.

What’s new in the model with electric start:

As already announced with the GOLD model, the cable routing from the battery to the starter motor has been updated. A redesign of the starter motor has also been incorporated that improves mounting with the exhaust.

The magnetic flywheel changes the configuration and increases the inertia, thereby increasing torque at low revs and achieving a more linear power delivery.

A new choke handle is added to make it easier to operate when equipped with electric start.

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.
