RR 250 RACE 2T
The new RR 250 RACE 2T has undergone a complete engine redesign for greater torque
and broader power delivery across the rev range.
Key updates include:
Shared crankshaft and cylinder with the 300 2T model – with revised stroke
(72mm ? 69.9mm) and increased bore (66mm ? 67.4mm) to maintain its 250cc
capacity.
Redesigned transfer port geometry with a new dedicated piston.
New cylinder head that has been redesigned to create optimal performance with the
new engine geometry, while retaining the dual spark feature.
The dual spark plug (on both the 250 2T and 300 2T) brings numerous benefits:
It offers improved distribution of ignition points in the combustion chamber, with a
consequent reduction in fuel wastage. This translates into greater carburation
stability at all engine speeds, and more precise control of the engine.
The engine's range of use is further extended, with the delivery of greater torque and
more power.
The two spark plugs are managed with a separated electrical system. This means that
if one of the spark plugs should foul, the engine will still be able to run, although with
less efficiency, allowing the race or off-road session to be completed.
RR 250 & 300 RACE 2T
Key updates include:
The gearbox has been modified, by significantly lengthening the second gear. This
has increased the smoothness when switching from second to third gear, with
enhanced riding comfort and stability during and after the gear change. The result is
a clear improvement in the bike’s race capabilities, where you can always identify the
perfect gear to face any situation.
The main bearings on both the RR 250 & 300 RACE are larger and stronger.
