2015 RR TWO STROKE
The 2015 RR Enduro two-stroke has
also evolved, with the 250 machine
featuring technical innovations and the
300 version getting special parts from
the 2014 Racing model.
300 RR two-stroke: The engine
comes directly from the 2014 RR
Race Edition and includes a new cylinder, combustion chamber and CDI.
The reduced width of the exhaust port
provides better sealing of the power
valve and provides improved throttle
response with a long and very linear
spread of power. The combustion-chamber profile, together with the
digital electronic control unit, continues to optimize engine output in every
stage of operation to increase the performance and rideability of the bike.
250 RR two-stroke: The engine’s
exhaust valve adjustment system
has been modified, increasing the
number of adjustment springs from
one to two. This change significantly
improves engine output, optimizing
the opening of the exhaust valve at
every stage of operation.
A new silencer for the 250 RR offers
a smaller-diameter internal core compared to the 300 RR, which improves
the response to throttle and increases
peak revs. o
