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-
cycle with four-valve technology, small valve angles, and extremely advanced
design of the combustion chambers.
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
4.3 The First-Generation Four-Valve Models.
