• Optimised, maintenance-free shaft drive with a new two-stage drive shaft.
• HP Gearshift Assistant for shifting up without the slightest interruption of
power and traction available as an option.
• Wide range of standard features and accessories tailored to the K 1300 R,
all offering the usual supreme qualities of a BMW.
Increase in engine size for signifi cantly better performance.
Like the K 1300 S, the new K 1300 R also benefi ts from the signifi cant
improvement and upgrading of the straight-four power unit now increased in
size from 1,157 to 1,293 cc. Maximum output is now 127 kW (173 hp) at
9,250 rpm, maximum torque is 140 Newton-metres (103 lb-ft) at 8,250 rpm,
an increase in power by 7 kW (10 hp) and an increase in torque by 13 Newton-
metres (9.6 lb-ft).
While the former K 1200 R reached its maximum output at 10,250 rpm, the
power unit in the new K 1300 R develops its maximum power at a signifi cantly
lower 9,250 rpm. A further advantage is that more than 70 per cent of
the engine’s maximum torque is available from just 3,000 rpm, just as the
K 1300 R offers more than 10 per cent more torque than the K 1200 R
all the way from 2,000 to 8,000 rpm.
This clearly refl ects the objective of the engineers developing the new
machine, focusing on even greater driving dynamics with signifi cantly more
traction and much better acceleration than on the former model already
so successful in the market.
Like the K 1200 R, the new K 1300 R comes with a shorter fi nal drive
ratio (2.91 instead of 2.82), improving both acceleration and pulling power
to an even higher standard.
All technical modifi cations serving to optimise the engine and drivetrain are
the same as on the new K 1300 S. The airbox comes with a modifi ed air fi lter
and a newly set-up intake funnel versus the K 1200 R to meet the greater
demand of the engine for a smooth and effi cient supply of air. And last but not
least, the oil cooler with its larger block again refl ects the greater power and
performance of the engine.
Sporting rear muffl er with exhaust fl ap.
Like the K 1300 S, the new K 1300 R comes with a new rear muffl er not only
making an important contribution to the machine’s “beefy” torque curve
and riding qualities, but also providing an even more powerful sound full
