BMW R 1200 ST
R 1200 RT and the R 1200 ST have been designed for dramatically reduced
weight compared to the preceding models as well as an impressive boost
in maximum power from the all-new 1170cc, four-valve-per-cylinder Boxer
twin.
the new Boxer engine produces 110 hp, 15 hp more than the outgoing R
1150 RT’s — and even 10 hp more than the R 1200 GS’s engine — while
retaining a broad, flat torque curve. Moreover, the R 1200 RT weighs an
astounding 70 pounds less than the R 1150 RT, while the R 1200 ST
undercuts the R 1150 RS by an amazing 55 pounds
As on the R 1200 GS, the RT/ST engine employs the latest BMS-K engine
management system. This is a completely integrated fuel- and
spark-delivery system that uses sophisticated electronics fed crucial
information by a host of sensors throughout the motorcycle. Anti-knock
control allows the use of mid-grade fuel without risk of engine damage
yet also maintains peak engine output when it is fed premium fuel. In
this way, there are no compromises; the engine does not need to be
“detuned” in the event premium fuel is not available.
