2009 R1200GS

The Tenere pic could be closer than you think. Yamaha are launching a 1200 version at the end of the year apparently, and maybe BMW are thinking of that by first introducing a 800/650 range, which could be complemented by a 1000 or 1200 long distance version. A 1200 Tenere would probably be much lighter than a current 1200GS and maybe BMW are worried about losing sales.

Well that is good news...it is about time that BMW started to take notice of other manufacturers....they have had the monopoloy for too long...

Very good news for us BMWphiles...the die hards will get the rewards with better pricing, models and styling....then again perhaps not...:rolleyes:
 
GS Monkey, why fall into the trap that BMW want you in... 08 is only just here....
I'm not falling into any trap. I bought the outgoing 07 model for a discount :thumb2

The 1200GSA has been fitted with a new type of boxer engine coming from the R1200R. It's pretty much a mid-life upgrade.
Hardly a new boxer engine. They've tweaked the ignition slightly, but its substantally the same drive train. Its a cheap end-of-model upgrade, not mid-life. The 1200GS has had its 5yrs.......... time for a new model :) The competition are moving in and hence BMW will keep developing to keep ahead.

Hopefully a new generation boxer will evolve............
 
1200 GS engine is 101 x 73 mm bore / stroke

800 GS engine is 82 x 75.6 mm

So not that much extra piston size for 1200, if they wanted to convert the 800 engine :)

Wonder if they'll go the 1 ltr route then up it to 1100 then 1150 then 1200 ;)
 
If they watercool the boxer (must be possible as per the CX500?) the stylist will struggle not to make it the uglyiest engine from uglyville.

Shep

I think my Subaru might have a water cooled boxer engine :eyebrow I reckon I'm on to something here. Does anyone have a phone number or BMW R&D? I'm sure it would be possible to lose two of the four cylinders (maybe even on oposite sides for symmetry's sake) Sorted. :beerjug:

Ok then, a motor derived from the 800, shared by the F series generally, suggesting perhaps that BMW have plans to develop it further for future models. The fairly limited tank range on the F800GS might somehow be increased to create a GSA version, perhaps if the engine is stepped up to 900 or 1000cc.

You are all on the right lines......watch this space for the Vtwin watercooled GS and later the Adventure....

It will happen....sooner rather than later....:thumb2
 
R1100GS 1994 to 1999 5yrs
R1150GS 1999 to 2004 5yrs
R1200GS 2004 to 2009?

Based on recent oilhead production development, you'd think that the current facelift is to tide the models over until a major development in 2009. Should be interesting to see what they come up with next.

Just hope the boxer is still up to the job with the new emissions / noise regs.

Hope they can keep the boxer going - would love to buy another at the next major upgrade. The 1200GS is such a great bike then any improvements will make it an absoulte must have.

Tell us what you know then - you can't just keep it to yourself ;)

Only from what I've read on this forum.....

A watercooled V twin is on it's way, the gap between the Adventure and a normal GS will widen, perhaps even introducing an even larger front wheel and stuff, to the degree that you would not be able to Adventurise a GS as easily as you can now....

The thing is, the marketing people are very smart. When a new model becomes available they introduce it without all the toys....then an interim model with updated this and that, a facelift model then an all dancing all singing model, then a limited edition or 'Special Edtion' (SE) just before they then introduce a complete new bike....the cycle then starts all over again...

Those that can afford to change do...those that can't pick up the surplus at discounted prices, those further down pick up good second hand deals from those that have upgraded and so on....phew...

I'm not falling for that again....I'm just waiting not upgrading or changing until the New, New bike arrives.........:blast

I think they'll loose more customers than they think if they don't (no big sticky out things to warm your slippers on)

I agree, this engine is legendary....but change is a difficult thing to adjust to- no one likes change...who said that the combustion engine would not catch on?...Must have been the Lone Ranger....Horse sh@gger...
 
porche have had liquid cooled boxers for many years. I guess the reason BMW have avoided that route in the past is the alienation it might do to us ludites, and the percieved complication of a simple boxer design.... but then it the them that added ABS, traction control, EWS, CanBus.....

So gents I think we can be pretty sure that at some stage in the futre we will see a true water cooled boxer, how they hide the radiator will be the interesting solution.

Now just imagine how much fun that will give to all you speculation monster, and following the first one you get another 10 years of new models to speculate on before the first fuel cell bikes arrive with there fuel celss convieniently shaped like a 1980 800GS engine...;o)
 
As its total speculation I think a totally new GS is more likley to be unveiled late 09 for start of sales early '10. Purely based on a) the level of investment and return on the 08 'facelift' b) the current investment ongoing with the WSB / Road bike c) the supposed replacement for the top of line LT d) the lack of return on the G range.

What it'll be I suspect no one knows but they've tried once to kill the boxer style and failed , Porsche have tried to drop their boxers and failed....and the emissions will not be a major issue to get over but the noise limits will be and that may kill off an oil/air cooled unit.

My friend who works for the company has reliably informed me that the new engine is in the final stages of development.....Its an 8 cylinder two stroke turbo diesel electric.....codenamed .......Das Deltic!

Boxer engines probably got their name because the pistons of the motor, when observed from the top, resemble the fists of a boxer pummeling his opponent.

One benefit of using a boxer engine versus a V-engine is that the design provides good balance because each piston's momentum is counterbalanced by the corresponding piston movement of the opposite side. Boxers are one of only four layouts that have a natural dynamic balance; the others being the straight-6, the V12 and the ****el engine.

These engines can run very smoothly and free of vibrations with a four-stroke cycle and do not require a balance shaft or counterweights on the crankshaft to balance the weight of the reciprocating parts, which are required in other engine configurations

:clap:clap
 
OK so a boxer motor is well balanced but I can tell you from experience that it certainly vibrates plenty. Also, displacing 1.2 litres of crankcase air every cycle gives the breather system a pretty hard time. And it has a balance shaft, why?

Yeah but......... there is a serious rocking vibration caused by the fact that the conrods are offset by a couple of inches or so on separate crank pins. The 1200 has a balance shaft and a couple of weights but it can't totally get rid of this rocking vibration, which gets more pronounced the harder the bike is working. The 90° twin, like the Ducati is far better in this respect as the conrods share the same crank pin.
 
.........not a lot of truth in the rumours so far then!
