K1200R Vibration at higher RPM

Hi everybody,

here is the other question i mentioned in my previews post:
http://www.k-bikes.com/forums/91-k12...vibration.html


Long story short i have a K1200R 2008 with 7860km. After riding it for a couple of months now I am getting braver
In the lower RPM like around 4000 the bike is really smooth. When i then accelerate and cross 5500RPM the vibration overall
noticeable increase. If i get close to 7000RPM its a lot more to the point that i start to shift into a lower gear.

Is this normal? According to BMW yes which is not really helping me to get a piece of mind.

Looking forward to your help.
Karsten

With a flat plane crank, short stoke and high compression inline four you are going to have vibration at high rpm due to the inherent secondary imbalance. This is normal, the tingly fingers effect. Don't stress about it, there are plenty of engine types that are smoother at higher RPM's but there is where our K bikes make all the power so.....
