What Year did the R1200GS engine get upgraded?

[jeffreyjames]

Was at the dealer today looking at an 08 I think, and he said the newer engines had more pep to them, and required less maintenance.. Do you know which year this was put in place on the GS?

The 2010 GS models get a new, more powerful twin-cam 1170cc motor that puts out 110bhp – a 5bhp up on the outgoing model and 15% more torque at 2500rpm.

LOOK OUT FOR… New engine on the GS has a different head cover with two not four bolts.

I'd be careful what the dealer sells you, just because the valves need checks less often, doesn't mean it's less maintenance.  An older design, like the 1150 I had, had valves that were adjusted with wrench and screwdriver at home in like 15 minutes - I don't believe that's the case anymore with the "upgraded" motor.  

Power upgrade?  Yeah, ok - what's the HP difference?  Is it noticeable?  Depends on the rider, but complexity is the tradeoff.

what is the recommended service interval for the new motor??

Valve checks every 6000 miles, same as the old one.   Now they are adjusted with 'semispheres', which is basically the same thing as shims in most other bikes.

2010 is when the DOHC motors came out, and they do have more pep. I just moved from a 2006 1200GS


to a 2010 1200GSA and the engine is noticeably smoother and faster at higher speeds.


I dont know anything about service and such, just know the motor has been improved.

2004 to 2007 saw the engines with 98bhp. 2008 to 2009 this was increased to 105bhp. 2010 on saw the twin cam engine arrive with 110bhp. All the bikes up to 2009 have valve adjustment by screw and locknut, from 2010 it is by the hemisphere shims. The first valve check for the twin cam is at 6000 miles.

I was told my 2009 had 110HP. Where did the 105HP figure come from?
The 2010 still has 110 hp but more pep down lower in the rpms. It is noticeable and the engine feels livelier and spins up faster.
If valve adjustments are more complex in the 2010 and 2011 that would have been a negative for me because more complex equals more money.
Also remember that 2009 (and earlier) had the old style turn signals and in 2010 they went to jap bike turn signals and the controls are just not as thought out.
The horn feels way down low almost underneath the grips. Very awkward to me.

The RT (and maybe some other models) went to a more standardized turn signal switch, but the GS retained the 'right on right, left on left' arrangement in 2010. not sure about the 2011+
