BMW K75, BMW K100, BMW K1100
These machines were developed by the same team at BMW, with the K100 being launched in 1983 and the K75 a year later.
As the name suggests, one is a 750cc and the other is 1000cc, both of the same bore and stroke, but with three or four cylinders respectively.
The DOHC engine with in-line cylinders was longitudinally installed.
The K100 1st Generation was produced from 1983 to 1989.
This was a 4 cylinder 8-valve 1000cc with Monolever suspension.
The police usually used the faired K100LT model made from 1986-91.
This used its 90hp to get to 133mph and 0-62 in 4.1secs
The K100 2nd Generation was produced from 1989 to 1993.
This was a faster 16-valve 1000cc machine with adjustable Paralever rear suspension.
Its 100 hp could take it to 144 MPH and 0-62 in 3.9 secs.
They were superceeded by the K1100RS (1989-99)
The K75RT was a 3 cylinder, 2 valve per cylinder machine of 740cc.
This produced 75hp, and a top speed of 116, with 0-62 in 4.6 sec.
Rear suspension, like the 1st generation K100, was also Monolever.
They were produced from 1989 to 1996.
