K1 (1988–1993).
In 1988 the K1 sets another milestone in the history of the BMW K-Series.
Apart from its brand-new design and aerodynamics concept remaining unique
in the motorcycle world to this day, the K1 is BMW’s fi rst production motor-

The greater cylinder charge achieved in this way is refl ected by the extra
power of the engine, the K1 developing maximum output of 100 hp at
8, 000 rpm – more than any other BMW before.

Featuring new Bosch Motronic fuel injection, 17-inch wheels and ABS, the
K1 also sets new highlights in technology, one example being the Paralever
double-joint rear wheel swing arm introduced a year before on the R 100 GS
and effectively preventing drive forces from the drive shaft and any undesired
effects of this kind on the rear-wheel suspension.

The K1 is also the world’s fi rst production machine to feature a fully-controlled
three-way catalytic converter, making a signifi cant contribution to
environmental protection and subsequently introduced step-by-step on
all BMW motorcycles as of 1991.

Production of the K1 ends in 1993 with the special Ultima model.
K 100 RS (1989–1992).
The innovative four-valve technology introduced on the K1 with its engine
output of 100 hp makes its way back into the market in 1989 in the highly
successful K 100 RS. While the combination of the fuel tank and seat as well
as the fairing with direction indicators integrated in the rear-view mirrors
corresponds to the former model, the new K 100 RS, like the K1, benefi ts
form new 17-inch wheels, larger brakes, and the Paralever single-swing arm
at the rear.

K 1100 LT (1991–1999).
In 1991 BMW presents yet another milestone in the history of the K-Series
through the introduction of the K 1100 LT, the fi rst BMW to displace
more than 1,000 cc: an increase in cylinder bore from 67 to 70.5 millimetres
(2.63 to 2.78”) gives the engine 105 cc more capacity, the upgraded K
