Kirk: I was wondering if that clutch lever was stock - I like those little
finger groove indentations.
From Mac Kirkpatrick:
Good eye Troy. This obversation is new to me also. Or I have forgotten
it.....(old age!!!)
Anyway the '74s had these different indented levers. '75 and later did not.
It is important to note that the number one rule when talking about R90ss is
that there are no firm rules. For instance, by this we should mean that
BMW did not end the model run for all '74 R90ss and also end up with no
old brake and clutch levers. And then start the new model year ('75) with
different levers.
Many of the changes were "running changes" and occurred sometime during the
model year run.
It is also interesting to note that not all serial numbers were used by BMW.
Go to
and read a letter from Pat Raymond of BMW to the '77 R100RS website manager.
A number of interesting points are made here, and one is that BMW did not
make bikes for all the serial numbers that they set aside to make.
Confused by my explanation? Sorry, go read the article, it is worth it.
This makes it confusing when trying to figure out how many bikes of a
certain model were made in a given model year. You cannot look the first and
last serial number in a book and subtract one from the other (and add one?)
to come up with the number of these produced. BMW did not use all the serial
numbers they had set aside for their model runs.
