I hope that the new F series bike are more reliable than the current R series bikes.
Some of the on going "issues" with R series bikes that come to mind are:
Final drive failure
Key ring replacement
Fuel guage readjustment
All of the above items, which are not formal recalls, will cause you to call for road side assistance and a tow to your nearest authorized BMW dealer.
The quality and reliability of the current BMW bikes have caused many loyal BMW riders to buy other brand bikes. I'm one.
An other indicator is the semi annual Iron Butt, and the number of DNF or BMW's that broke down.
Buy a V Strom for a lot less money and the same amount of fun. You can spend your time talking about your rides rather than how the dealer fixed this and that under warranty.
