Due to some technical highlights I am posting this thread again. Many thanks to our Admin Havit!!! He had lots of work with me the last two days. Now to my story: Last Wednesday we could finally complete the family reunion of the TIGER-BONNIE family. My wife's 900 TIGER had a warranty replacement of the entire rear brake system, so it had been away from home for several days. The brake had to be bled constantly, but after the 3rd time we had everything replaced. Now all 4 bikes are finally together in our garage. I had the "cool" pleasure to ride the TIGER home from the neighboring state for +100 km at temperatures from -1.5 to + 3 degrees celsius. My wife drove our car as transport and escort.
I haven't changed my mind since the first posting of this....your wife still had the better (warmest) idea!!!
