Shift cam or not?

Is it a Shift cam or a Shit cam?

I have watched this video. The essence seems to be that Ryan expected more from a new, improved model.

Personally I have not found any of the jerkiness faults he mentions. And the important in-gear acceleration figures (that reflect torque and gearing) are better than a KTM 1290 Superadventure, though the KTM will indeed out-accelerate the 1250 GS from a standstill.

The only way to verify his words are to take a test-ride.

Everyone is entitled to their opinions, and I usually quite like this guy's videos.

But I disagree with him on this one - my bike's super smooth and there's no indication of the cam doing it's stuff (unlike my VTEC honda back in the day).

I have done a side-by-side acceleration test with the KTM (which I used to own myself) and the GS is best until stupidly illegal speeds.
IMHO 99% of people would be quicker A to B on the GS (and arrive more relaxed)

I think it's a poor review.

For example, he picks on the fact that it doesn't have variable valve timing and picks on the fact that the two sets of intake lobes can only hit one sweet spot, whilst promoting the Suzuki variable valve timing - whilst almost completely ignoring the fact that the benefit of flow due to the greater lift of the two stage system. That and the fact that the lower lift/duration lobes open the valves at slightly different times means a better combustion at lower rpm.

Or he he suggesting just about every other bike has a better solution with a single lift/duration inlet lobe/s?

He picks on the shift mechanism is operated by a solenoid, because it might fail - have any failed yet?

More laughably is the comment about the oil filler - you'd thought an intelligent person would realise that the screwdriver handle is moulded in the shape of the filler head and the spanner fits the screwdriver to provide the leverage required - there are only a few pcs to the tool kit and he can't work out what they're for?

Finally, why make an issue of the fact that standing on the pegs, the speedo can be obscured by the sat nav mount - bit of a daft comment really.

Cant fault my one either, its me that lets the combo down, not the bike.

 

[Wierpig]

Don't know if it suits the GS more or not but the shift cam in the rt is a far superior motor than the old lc

Shiftcam = EU regulations. Pollution (sound and exhaust emissions) + BMW fantastic spin to fool and convince a select person.
The BMW advertising section of Shiftcam have done an absolute belter .......

I take it you own one then with your expert comments or perhaps in the dark ages of denial

Basically he’s a bit of a twat to summarise

Not sure to have knowledge of something specific, means you have to personally own it ?

This video has been debated in here recently, hasn't it?

In my eyes this video is purely Clickbait.
He brings up several silly angles of twisted views and fills his 15 min video.
Gets plenty of people fired up = They see the video again = more income to the producere since he gets paid per click to his video.

He may make some perhaps extra needed income on this video, but at the same time he blows his integrity down the drain...

 

[Delboy777]

Clickbait, is what this post is too.

 

[Micko123]

The VVT system employed by Kawasaki in 2007 on the GTR 1400 was hydraulic cam phasing up to 27 degrees on the inlet camshaft only.
Ducati went 1 better in 2014 on the Multistrada with both inlet and exhaust hydraulic cam phasing up to 45 degrees.

In 2017 Suzuki went for mechanical cam phasing on the inlet camshaft only on the GSX-R
1000 (probably to ape their GSX-
RR MotoGP bike where hydraulic and electronic VVT systems are banned).
Honda used the Hyper-VTEC system on the VFR800.. but that wasn't cam phasing just a 4 valve per cylinder engine restricted to 2 valves per cylinder up to 6,500 ish rpm and 4 valves above that speed. Relatively crude compared to various car manufacturers with much better but more complex bulky systems, on a motorcycle space is always at a premium and cannot easily be accommodated.
None of the above systems give variable valve lift or duration,
at least BMW with the shift cam engine partly ticks both those boxes because it has 2 separate cams with different lobes ... higher lift, longer duration and different phasing compared to the low rpm cam. So Ryan can scoff all he wants, it's a better more flexible system than any other motorcycle maker is currently producing, proved by the emissions, power, torque, MPG figures that the current 1250 makes. None of this matters much anyway because in 10 years time you will probably only be able to buy electric bikes anyway.

But ownership allows a correct view and honest information , test rides mean f all .

That must be why the Challenger shuttle failed .... If only they owned it LOL
I know 1980's Skodas were shit, or I thought i did , as now im confused.... As ive never owned one. Oh well, .....

Challenger shuttle, not really a good example that one.
Ref pre german skoda, had one, got to admit not the most exciting driving experience but it ran for years and years without missing a beat or rotting away. Maybe Stick is right.

 

[Deleted account 250319001]

Maybe

 

[Deleted account 250319001]

Although its absolutely obvious that he's just pissed as someone has pronounced negativity towards his new super steed
Does tickle me how sensitive some folk are....
Listen to Ryan, Shiftcam is obsolete old , out of date 1980's cheap rubbish. (EU Emission Regs)
Bit like my Remus 8 Stick aye

 

[Engineer]

The 1250 has big gob more of torque, more than one would expect perhaps from just the capacity increase? So what’s not to like if it gives you greater ooomph and still meets all the regs.

Nothing

However, The greater Ooomph as you put it, is just the side affect of the shift cam and greater cc to get it through the tighter regs.
All a bonus. Just wished they'd used proper VV than the old shite they have decided to go with, Cost I suppose ?
Maybe the R1300GS will have proper VV , who knows ?
