The new 1250cc Boxer Engine with BMW ShiftCam 

Can't tell enough how much I love this technology explanations

This is the reason there on top. I’m for one glad to be part of the Bmw family.

Damn those BMW engineers are good. I love the fact that BMW is explaining clearly how something that technical works. Thanks guys.

Adding another 50ccs to the engine is phenomenal when it comes to power! 4 valves per cylinder is a huge improvement too! This Bike is going to take you places! The trick is to learn how to make the engine do its best without delivering too much power for the need that's presented. Great job R&D department! It is liquid cooled too I hope! This is a real improvement!

Wow, and thrice wow! how good is that for technologiy? I'm humbled and emotional just watching this short video,... mankind at its best. Thank you.

Just another flavour of vtec. Honestly pretty much every carmaker has this kind of valve timing system with different names

What Bmw didn’t mention is that the cam gears will wear out prematurely and, for most of us, just out of warranty. When my 1250gsa was in for 20000 km service I was told that the cam gears were worn out - a very expensive repair. The service workshop suggested to Bmw that, given the low mileage of the bike and given that it had been fully serviced at Bmw workshops, they ought to bear the cost for this repair, especially since this isn’t something that should break down at all. Bmw Motorrad replied that they would take 0% of the cost. It was the same thing two years earlier, when the throttle handle and the engine harness broke a month out of warranty. No good will at all from Bmw despite a faulty construction being obvious. In the end the service workshop settled to change the cam tensioner on the left side, but most likely the problem will come back in a year or two. The service shop said that most 1250:s with shiftcam has cam rattle. Bmw denies it. I checked some Bmw forums and quite soon realised that the workshop statement was correct - a lot of 1250 owners have experienced the problem. Apparently also a few 1300 owners. I traded the bike for another brand but I will never again buy a Bmw. You pay premium for a Bmw and should be able to expect a qulity on par with the price. But insted you get poor quality wih no responsibility taken by Bmw. Similar story on the car side of things. Bmw make bold claims that cam timing chains are so much better than belts, but a fact is that the chain fails way more often than the belts used by other manufacturers.

Shiftcam just kicked in yo

So it's basically V-Tech for BMW motorcycles? Love the concept, and it's super cool. Just wondering if it's in the same ballpark?

Wow ! Implementing VVT system (Double VANOS ^^) in a motorbike engine ! Well done ! This engine will have a real double personnality ! Can't wait to test that !

Is there any automatic decompressor device in this engine? There are a number of R1250GS owners complaining about starting problems, so wondering if there is any device relieving the electrical system during the start.

What makes each of the two pins raise and lower to shift the cam across? Hydraulic/electric/mechanical? When it comes to reliability I guess the cam shaft is good for many hundreds of thousands of miles, and whatever the shift device is is just under the cam cover to easily accessed if it becomes faulty?

The differential intake timing on the partial load setting is interesting. Would love to know more about the engineering/physics thought behind it.

nice ride

Simply the best boxer ever!

Please BMW, tell me the news? Honda launched Vtech in 1983! Simpler system doing exactly the same...

Checking the valve lash will be interesting

Great video showing the inner workings. What about valve clearances, I can’t see any buckets or shims in this footage, how are the clearances set?

Best technology ever, am in love ❤️😍

Great Motorcycle.

there are many 1250 with camshaft problems

So you made a manual laterally sliding vtec engine instead of an oil actuated separate lobe on the cam it has a sliding shift gate. Should’ve just copied the vtec from Honda seems more reliable than a camshaft sliding back and fourth

How may I get new BMW R1250 GS from factory market, not from dealer???

We are looking forward to Intermot to see it!

WTF is 'Sovereign Acceleration'? 😆 I need some of that in my life

Good evolution. Now TFT screens for your K bikes please. These models are behind.

Beautifully simplistic. Like most of my marriages.

Yes, but when are you going to MotoGP?

*SHUD'DUP 'N TAKE MAH MA~* wait... *Checks the price* ._.

Waiting for all-new R1250GS Boxer Engine Production clip this year or in 2020 ^^

pity this system is the same called i-vtec made from Honda 30 years ago (VRF 800)…what a new!!!

INTERNATIONAL MEETING BMW BOXER IN BENASQUE-THE PYRENEES-SPAIN 14-16 JUNE 2019

This is the Valvelift system used first by various Audis... When did you stop trying?

Is there a lag when the shift gate does it's "thing". ???

Best. Of the best.

great by bmw.hats off

So beautiful

Why arent the intake valves synced in the first mode?

I wonder how will it sound with 270 crank 🤔

Wow !

A Honda GL1800 Gold Wing também começou com 1000 cc, mas está na frente. A GS também chegará lá, concorrendo com o mesmo tamanho de motor da Gold Wing. The Honda GS 1800 Gold Wing also started with 1000 cc., but it is in advantage with its 1800cc motor. The GS will also get it, will have motor with the same size. It is in the right track.

Nice vtec

Awesome.. would like to buy one .. but no money 💵💵

Great but when is the g310r going to get a centre stand and heated grips??

Here’s the thing. Like some riders (but far from all riders) I prefer the sixth generation Honda VFR. Yep, it has a bipolar personality; sedate below 6700 and manic above it. And, some find the somewhat abrupt transition a tad abrasive. But, I love it - wouldn’t trade it for anything. In the name of refinement it’s possible to engineer the character out of an engine: Is this what ShiftCam has done? Let the debates begin . . .

Single cylinder?

How reliable is this though?

What is this ? Some vtec thing?

What rpm is the shift point? Is there hysteresis?

So... VTEC?

Looks like expensive service - I will hold on to my 1998 Africa Twin!

This is one bogus video, the intake valve timing is way off. Have a look at 1:40-1:43 and watch as the intake valves are closing as the piston is coming to top dead center (TDC). There would be almost no compression on the fuel air mix. As it stands, this engine would make no power - Please tell me that the real engine will have better cam timing than this. Also, that pin being used to shift the cam will shear off. Plus what holds the cam shaft in either position after it has been moved? Luck???

Better power outlet than my skoda fabia🤣🤣🤣

too much technology, my love belongs to the simple boxer engine with easy maintenance.

Worm gear excellent should be durable

❤️

Nice👍🥳🎉

So... did Honda’s patent expire?

Grate , gave 1995 GS with plastic gas tank which could cost me My life , since the plastic was disintegrating. BMW didn't do anything , didn't send any recall or notification to the owners . When I called BMW they just ignoret me . The offed my new gas tank for around $1800 . Thanks you BMW I'm definitely not gonna bay any product that you made . Shame on you .Martin

Neat

Where is the new S1000RR?!

sure looks simpler than the vanos on their cars, maybe not accurate enough for emissions standards to dump the complex car system.

Mantap. Motor seharga 1 M

Old technology. Audi is being using similar technology for a while… in cars… of course

Honda calls this Vtec 😬

exactly staid copy of honda s2000 vtech tech but more complex and prone to failure

Kok keren ya

Very nice BMW... Can I have one for free plz... I'm poor :)

😍👍👍👍

vtech with different mechanism.

🇩🇪🇱🇰💖💖💖

Why would someone want (or use) 136 hp on an off road motorcycle? It is beyond me.

VTEC…

De qualquer

"Sovereign Acceleration and Impressive Elasticity" and "fascinates in its diversity right from the very first moment" ?? Who authored this nonsense? Who reviewed it? It says nothing that truly describes either basic improved valve lift functionality versus rpm/engine demands and the benefits derived thereof. I don't feel inclined to move away from my 2015 RT and become a test pilot on new technology that BMW can't even describe properly in this video and detail its level of maturity in testing.....no thank you.

Better reduce weight than encrease displacement. BMW aren't fat cruiser

Unreliable, expensive repair and will not last 10 years/200 000 km...

just another BMW thingy

Getting too complicated...

Most stupid idea ever!

oh wow, bmw invented vtec.

Mony

V-tech....nothing new. Maybe just in Germany.

Bmw is now copying Subaru with Boxer Engines.... COPY CATS!!!!!!!

Worst engine in all GS history. Unreliable piece of crap.
