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.
