Flat spot on a R1200GS?

[Tramperman]

Hi all, my first thread.
Ive just read on another thread that there is a flat spot on the 1200GS.
Ive never noticed it, mines as smooth as a babies bum right through the
rev band.
Anyone else noticed it?

In several dyno' tests of the 1200gs there is a dip in the power at around 3000rpm but it's rarely noticable on the road. What may be thought of by some as a 'flat-spot' is a lack of oomph in top gear roll-ons until it hits about 5500-6000 after which there is a noticable surge of power. Despite BMW's claims of 100bhp, the standard 1200 makes far less at the back wheel and is on paper profoundly gutless for such a large capacity modern engine, however, on the road it's torque that matters and there is usually enough of that to make us happy.

This is an interesting site:

There's a wee dip at just over 5000 revs - it's there because the fueling is set for emissions regs.

Ditch the 'cat' and fit a less restrictive silencer and it almost goes.

Fit a fuel contoller and dial out the 'leaness' at that point and it disappears altogether.

TBH though it's not much of an issue, the engine has so much torque that you can ride around it, that's if you notice it at all

Its been there on every 1200GS I've ridden. Earlier bikes (04) are much worse than the later versions. Remus downpipes help reduce the effect.

Its there on most modern bikes to some degree.

Of course, if you're not trying very hard, you'd never notice it
