The second generation of BMW Motorrad’s four-cylinder power
units has been upgraded and updated in the interest of even more
power and performance, extra torque, and supreme riding dynamics.
Displacement of the four-cylinder inline power unit in the K 1300 S is up
by 136 cc from 1,157 cc to 1,293 cc. Maximum output is 129 kW (175 hp) at
9,250 rpm, maximum torque of 140 Newton-metres or 103 lb-ft comes
at 8,250 rpm. In absolute fi gures, this is an increase in engine output by 6 kW
(8 hp) and an increase in peak torque by 10 Newton-metres (7.4 lb-ft).
While the former K 1200 S had to be revved up to 10,250 rpm to develop its
maximum output, the power unit of the new K 1300 S develops its maximum
power at a relatively low 9,250 rpm.
A further sign fi cant advantage is that more than 70 per cent of the engine’s
maximum torque is available from just 3,000 rpm, with 10 Newton-metres
or 7.4 lb-ft more torque available all the way from 2,000–8,000 rpm versus the
K 1200 S.
The objective in developing the new model was obviously to enhance the
already high standard of riding dynamics and sporting characteristics
through power and performance easy to handle at all times. And weighing
82.8 kilos/182.6 (K 1200 S: 81.3 kilos/179.3, in each case including the
clutch, gearbox and oil), the upgraded power unit of the K 1300 S remains
one of the lightest engines of its size in the market.
Like the previous model, the K 1300 S benefi ts above all from its carefully
conceived overall confi guration as well as the space-saving arrangement
of ancillary units and the integrated gearbox. In all, this makes the entire
drivetrain very compact, with ideal concentration of all masses in the middle
of the machine. And as on the K 1200 S, the overall width of the power
unit, measured on the level of the crankshaft, is 430 millimetres or 16.9".
The perfect interaction of technical solutions and optimum integration of
the engine and running gear already featured on the K 1200 S is fully retained
on the K 1300 S.
