I'm a happy new owner of BMW Rockster.
I bought it as a second hand bike in Munchen, Germany - the city where all BMWs come from!
Just have a look at the photos below and you will see that the previous owner took care of the motorcycle in a best possible way. The original exhaust was modified by a german company to have a better sound and I can confirm it sounds perfect.
