Design patent drawings show what is the 2019 BMW
Motorrad S 1000 RR, which is likely to have its first public showing at the
EICMA show in Milan, reports website Asphalt & Rubber. The drawings show
what is an all-new engine for the S 1000 RR, with a counter-rotating
crankshaft.
Among rumours on the new S 1000 RR reported, it is
said the new BMW superbike might get variable valve timing along with engine
internals taken from the BMW Motorrad HP4 Race. The four-cylinder power plant
is housed in a new twin-spar aluminium braced with a braced swingarm,
reminiscent of the type fitted to superbikes from the 80s.
The exhaust system is a massive unit, with a
three-part construction containing the catalytic convertors and muffler separately.
This is likely to be in anticipation of the Euro 5 emissions standard due to be
implemented in 2021.
Another change from the previous generation S 1000
RR is the rear sub-frame, the square-section unit being replaced with a
round-tube trellis. This is probably with the intent of making the rear
sub-frame stiffer without compromising weight.
Visually, the biggest change is in the front, with
the asymmetrical headlights gone, and twin equal-size LED projector headlights
taking their place. The air intake is still located between the headlights but
appears to be slightly slimmer and shallower in the 2019 BMW S 1000 RR.
