Hold onto your helmets, folks, because BMW might be gearing up to release a serious game-changer in the world of motorcycling.

  • Next-generation G 310 series to be equipped with BMW’s ShiftCam technology. 
  • The ShiftCam system will boost the bike’s performance and fuel efficiency. 

The German automaker has just filed a patent application that hints at a potentially groundbreaking development: a ShiftCam-type variable valve timing system for a single-cylinder engine. And if the rumors are true, this could be a major step forward in terms of efficiency, power, and emissions reduction.

The patent, which was filed in August 2021 and published by the German patent office on February 16, 2023, reveals that BMW has been working on a valve actuating system that can control the timing and lift of one or more valves simultaneously. By connecting multiple cam pieces, or using a single cam piece with multiple contours, the system can deliver enhanced performance across the board, from improved power and torque to better fuel efficiency and reduced emissions.

The implications of this technology are huge, especially for BMW’s G 310-series of motorcycles. With a more compact design and a weight-saving valve train, these bikes could potentially offer even more agility and responsiveness on the road. And by incorporating two or more actuation profiles, riders might even be able to customize their riding experience based on their individual preferences or the specific demands of their chosen terrain.

Of course, BMW has yet to make any official announcements about the new technology or its plans for integrating it into future models. But given the company’s history of innovation and its commitment to sustainability and efficiency, it seems likely that we’ll be seeing some major updates to the G-Series and other models in the near future.

BMW Motorrad didapati telah memfailkan paten terbaru pada Ogos 2021 yang jelas memaparkan sistem ShiftCam pada enjin satu silinder. 

Berdasarkan paten tersebut, sistem ShiftCam itu akan membantu mengurangkan berat, meningkatkan tahap efisien penggunaan bahan api di samping memperbaiki kuasa dan tork enjin sama seperti teknologi ShiftCam yang terdapat pada enjin Boxer ketika ini. 

Ini bermakna terdapat kemungkinan besar jentera satu silinder seperti BMW G 310 R, G 310 RR dan G 310 GS akan dikemas kini dengan sistem ShiftCam tidak lama lagi.

Buat masa ini tiada pengumuman rasmi daripada pihak BMW mengenai perkembangan terbaru ini namun mengambil kira BMW sering menaik taraf jentera sedia ada, tidak hairanlah jika sistem ShiftCam ini akan direalisasikan pada enjin satu silinder dalam masa terdekat ini. 

JIka benar, maka kemungkinan besar generasi seterusnya BMW G 310 akan mendapat naik taraf yang signifikan. 

Enjin Boxer BMW R 1250 GS dengan “ShiftCam” – Sumber imej:

  • Desas desus mengatakan bahawa model R 1250 GS yang baharu akan dijana oleh sebuah enjin Boxer baharu dengan pemasaan injap boleh laras.
  • Satu video promosi telah muncul di atas talian mengesahkan khabar angin tersebut.
  • Video itu juga telah menunjukkan bagaimana teknologi “Shift Cam” berfungsi serta rupa GS yang baharu.


  • It has been rumoured that the new R 1250 GS will be powered by a new Boxer engine with variable valve timing.

  • A promotional video has surfaced online confirming the rumors.

  • The video also illustrates how the “Shift Cam” technology works besides the look of the new GS.

It was hotly rumoured that the new 1254cc Boxer engine in the new 2019 BMW R 1250 GS will feature variable valve and cam timing but there was no concrete proof. But now, a promotional video has surfaced online which illustrates the new Boxer engine with “Shift Cam” technology, courtesy of

The system aims to provide the best acceleration along with high power gains, while maintaining smooth power delivery, and lower fuel consumption as well as exhaust emissions to meet the tough Euro 5 standard.

To achieve those targets, the BMW Shift Cam system is simple, utilizing an intake camshaft with two cam profiles and a mechanical shift gate at one end.

At low engine loads (lower RPMs), the shift gate engages the camshaft and locks the low lift and short duration cam lobes over the finger followers. That way, both intake and exhaust vavles shut quickly for less overlap, promoting low-end torque.

Conversely, at high engine loads (higher RPMs), the shift gate… er… shifts the camshaft to present the high lift and longer duration cam lobes. Consequently, the intake valves shut later for more valve overlap timing, raising the engine’s power output.

It is the best of both worlds. (You may read more about valve overlap in this article.)

The new Boxer is claimed to produce 136 bhp and 143 Nm of torque, up from 125 bhp and 125 Nm of the present 1176cc engine.

Besides seeing how the new engine works, the video also revealed how the 2019 BMW R 1250 GS will look like.

As we have reported earlier, the new engine may also power the entire Boxer-engined line-up. The R 1250 GS and new models should make their first official appearance at the Intermot show in a few weeks’ time.
