Euro 5 on the doorstep Watercooled

[Engineer]

Pretty sure the cooling system is unchanged on 1250

I had assumed that was the case and that Euro 5 was met by the shift cam and cat changes, but I could be wrong and would like to get the info from BMW.

I did say on my original post that i wasnt sure, and i stood to be corrected, seems i was sensible enough to add that caveat. Have a nice day

To late he seen he was mentioned and decided to do a ghost, obviously has other things to do.

Bolting more "shite" onto my 1250

Only if it is Euro 5 approved, ya thrifty

I believe they increased Overall cooling capacity but I assume that’s bigger rads rather than internal changes.

I dont disagree, never having had a 1200LC i dont know but in my kak handed way thats what i was meaning by Full Lc

Just read through all of the changes engine wise. Other than increased water capacity, the main change to keep combustion chamber temps down is an additional oil jet directed at the bottom of the piston crown.

Yeah well its "second hand shite" so not fit for some peeps bike's, but perfectly adequate on mine. I know the right side of a quid dont ya know.

So I guess they’ll have to start looking at either introducing some exotic metallurgy to the engine internals or just ensuring the engine will last for one PCP cycle or until the warranty expires.

Well done that man

Unfortunately we live in a throw away society nowadays. But i dont know many who can afford to throw away an 18k bike every three years,

At least you will get some value out of your new tools, and the LC,s now are looking very nice indeed.

Do you have a link?

Just go in the bar and speak with the PCP crowd.

So no additional water jackets, still just the valve cooling bit, I.e. partial cooling.

I dont suppose given the design of the engine that they could squeeze water jackets round the pistons, so oil jet at piston crown would very nearly do the same job dispersing the heat.

I personally was with my friend who is a top technical guy at BMW yesterday, and he is saying he is woorying about the life of the engines with these new emission standards.

Did you friend explicitly express that he thought the leaner running would ruin the engine?

My reason for asking is that my 1250 that meets E-5 burns almost as much gas as the 1200LC, perhaps 1 or 2 % less, and surly not much different.

Also, prior to introducing the E-5, the European manufacturers lobbied heavily for some sort of time limit on the 'lifespan' demand for the E-5 standards. Their claim was that while cars usually have a lifespan of 15 years (+/-) motorcycles typical lasts much longer. While a bike on average run up less miles, the timespan may make it hard for owners to maintain older bikes du to lack of needed spareparts. So they worried about fully working bikes would be scrapped due to nitpicking MOT (where MOT is performed).

From BMW Will

The concept is supported by the new digital engine control and an electronic fuel injector with an opening width of 52 mm and what are known as “two-jet injection valves”. The engine lubrication system was also optimised, and has an oil supply which is adapted to the riding condition and style and piston crown cooling with injection oil.

I read through several Docs from bmw but this was the best for detail

That was a good read. Well done for tracking it down.
