New (to me) K13GT - new guy saying "hey" and some questions about bike

Hey all, I learned to ride in 2008 and picked up a new F800ST back then, and finally felt ready to upgrade to a K13GT. Found a perfect one up in Frederick MD and flew up to buy and ride it home yesterday. I love it! It's got just over 11k miles and all the factory options, even has LoJack and 49L rear topcase installed.

On the way home, in my limited 300 mile experience on the bike so far, I noticed that the engine was very smooth, except when you close the throttle very slightly, like say to slow down by a MPH or two. Doing so introduced a noticeable vibration. Is this common?

Also, I found the saddle VERY soft so I'll be looking for a replacement, but noticed the rear section of the driver's saddle was more firm than the front section by the tank - weird!

I'll probably be a regular here - nice to find a K specific board!

Mine vibrates when decelerating as well. I've always assumed it was just part of having a shift drive, as none of my belt or chain driven bikes do it.

Was thinking the same. My F800 has a belt drive and it's smooth upon decel, although it vibrates a lot more at all other times where the K is smooth at all times EXCEPT decel.

I bought my 2006 with 18k miles...now has 44k. I don't notice a vibration at lower speeds but the acclaimed jerkiness when trying to keep a low speed.

Make sure you read up and update all the maintenance needed on these well engineered machines.

Basically:

cam chain guard
cam chain tensioner
change rear gear oil
shift lever roller bearings (optional)

You're talking K12, but mine's K13, slightly different but don't know precisely how much.

The original owner just had 12k service done (prior to even hitting 11k miles!?) so I assume BMW did everything properly and it has all been checked, but I may have my local dealer inspect it just to be sure, since it's got warranty remaining until Sept 2013.

Another thing I noticed was somewhat sluggish throttle response. Like there is a delay between twist and "go" - I wonder if this is also normal.

Another thing I noticed was somewhat sluggish throttle response.(same of what I refer to as trying to keep a low speed. Either its on or off at a certain point) Like there is a delay between twist and "go" - I wonder if this is also normal.
I'd advise to check into the items noted.

My bike (a 2007 K1200GT) does exactly the same thing. I think it has to do with fuel being shut off during deceleration (as is common on most modern FI systems.)

There were frequent complaints of touchy throttle on the earlier bikes so BMW dulled the throttle response a bit. Then people complained that the bike wasn't as responsive. Sometimes you can't win...

That's BMW's way of telling you not to slow down, but to go faster . . .

cam chain guard - good idea
cam chain tensioner - already done on K13GT
change rear gear oil - good idea
shift lever roller bearings - already done on K13GT
