I have taken the plunge and replaced my (near) 40,000 miler with ... another silver TDM900A.
Very low miles and very much less cost-to-change than a new Tracer which was, to my mind, the only realistic alternative.
So far so good, although engine does not seem as smooth as my (very well run-in :-) ) example.
The bikes is spotless and I kept my own (Givi) luggage etc. ... all set for rest of the summer into the future and hopefully will last me another 40,000 miles or more ...
