I'll
be honest. At least, I'll try to be honest. I never liked BMW
motorcycles much. They seemed to be awkwardly engineered and
inadequately styled. However, in all cases, they proved to be
superbly engineered and awkwardly styled.
This is why there
might still be hope for the new Rockster. Again, it seems to be on
the wrong end of a pummeling and, in the general world of
motorcycling, the Rockster will have the crap beat out of it by the
school bully.
However, as I
mentioned, I have been wrong before, in regards to the engineering.
And, this is where the Rockster will have to excel.
Still based on
the standard flat twin "boxer" engine, the Rockster
apparently has a 'distinct identity of its own'. What exactly that
is, we are not sure, but expect the 1130cc, four-cylinder to pump
out a characteristic 62.5kW at 6750rpm and a distinctive 98Nm at
5250 rpm. What makes this distinctive motorcycle distinctly distinct
from the 'normal' R1150R is the fact that these figures are distinctly
the same.
Other performance
figures include a 197km/h top speed and a rather impressive claimed
fuel consumption of roughly five liters.
Housing the
engine is the usually impressive BMW chassis. The Rockster should be
rock solid with its Telelever and Monolever suspension system. The
previous R1150R left many riders complaining of vague front-end
steering and poor feedback. However, after a few hours, you soon get
used to this. We suspect that the Rockster will be similar in its
attributes.
The R1150R is one
of the most sophisticated rides available and the Rockster seems to
have added the character that the R so desperately lacked.
Some technical
information is the explanation that the Telelever system on the
front of the Rockster. The forks are still telescopic, but feature
no form of damping or springing. The forks are filled with
lubricating oil, this keeps the unsprung weight down, and there is
only one fork yoke. This structure is attached by the outer tubes to
a rather substantial swingarm.
Above the
swingarm, there is a single spring and damper set that pivots on the
engine casting. This system reduces dive under braking, reduces the
weight of the suspension and in this way keeps the handling of the
motorcycle predictable throughout the suspension's travel.
Another handy feature on the Rockster is the standard BMW
Integral ABS system in the partly integral version on the Rockster.
This partly integral system activates the front and rear brakes
simultaneously when activating the hand brake. At the same time,
this innovative braking system enables active reaction to dynamic
wheel load changes that occur during braking, thus enabling optimal
braking power every time, and a very short braking distance. |
