The 2019 BMW S1000RR is one of our most anticipated motorcycles for this model year, and for its media debut, BMW Motorrad set up a press launch at the esteemed Circuito Estoril in Portugal. Unfortunately, BMW Motorrad didn’t think to invite Asphalt & Rubber to this superbike’s press debut, but we showed up anyways.

This is because BMW Motorrad did invite our friend Jonathan Balsvik to the launch, despite his publication – Sweden’s Bike magazine – recently shutting its doors. With Jonathan looking for a place to publish, and us eager to share what this new S1000RR is all about, we bring you this ride review. Many thanks to Jonathan for helping us bring the good word of the “Double-R” to the sport-biking masses.

It should be noted though, that because of the heavy rains during the press launch, Jonathan’s review is a bit limited in what it can cover, both because of the rain-soaked track and because of BMW’s control riders, who slowed the pace of the track sessions quite considerably.

With these limitations in mind, we hope to bring you a follow-up review in the coming months, assuming BMW Motorrad USA can provide us with a bike to ride. -JB

It is not like the BMW R1250GS Adventure was a big surprise for the 2018 EICMA show. It’s debut was telegraphed in emission documents filed with the California Air Resources Board (CARB), and photos of the machine recently leaked onto the internet.

But, the GSA has always been an important motorcycle to the German brand, and as such, the debut of the 2019 BMW R1250GS Adventure is a bit of a thing.

As expected for the 2019 model year, the big feature on the R1250GS Adventure is the addition of BMW Motorrad’s “ShiftCam” boxer-twin engine. Getting a bump to 1,254cc, this increase in displacement means that there is a modest performance increase of 134hp and 92 lbs•ft of torque.

One of nine new motorcycles coming from BMW Motorrad for the 2019 model year, the new BMW R1250RT is one of five BMW models getting an updated boxer engine that uses “ShiftCam” variable valve timing (click here to see the BMW R1250GS).

The new engine promises better throttle response when touring and at lower speeds, while still providing a sizable power increase at full throttle, to the tune of 134hp and 92 lbs•ft of torque.

The rest of the BMW R1250RT goes largely unchanged from the previous model, however, though BMW Motorrad has added a few notable enhancements beyond the new boxer engine. Specifically, dynamic traction control (DTC), automatic stability control (ASC), and hill-start control (HSC) are now all standard on the 2019 BMW R1250RT model.

We have known about the 2019 BMW R1250GS for some time now. Details about the bike’s new boxer engine were published over a month ago, which tipped off the use of variable valve timing on the venerable GS. We also learned that a displacement increase of1,254cc  was coming, and with that a modest power increase of 134hp and 92 lbs•ft of torque.

Then last week, we got a teaser of the 2019 BMW R1250GS adventure-tourer, as a promotional video was leaked onto the internet, and it showed us in great detail what to expect from BMW Motorrad. More specifically, the video showed us the German motorcycle manufacturer’s new variable valve timing technology, called ShiftCam.

Providing two possible cam lobes for each valve, the camshaft shifts position in the cylinder head to engage one of the two lobes, depending on throttle inputs. Hence the name, ShiftCam.

This allows for different intake valve actuation (timing and stroke) during touring and city riding, for better gas mileage and softer throttle response, but still leaves the engine the ability to wake up during spirited riding, and provide more power.

The new “ShiftCam” boxer engine is coming to all the “R” bikes in BMW’s lineup for 2019, which of course includes the 2019 BMW R1250GS.

We have known about the 2019 BMW R1250GS for some time now, but today we get our first real look of the machine, thanks to the bike’s promotional video, which has leaked on the internet (hat tip to the folks at Motorcular.com). And, despite everything we knew about the BMW R1250GS, the Germans still managed to surprise us.

This is because instead of the “Shiftcam” technology that BMW Motorrad has developed for its revised boxer engine.

Originally tipped to have variable valve technology, we now see how BMW is going to achieve this goal, and the answer is with a camshaft that has dual lobes and a shift gate that engages the high valve lift set during full throttle applications.
