Jbay,
the other option would be to spend some small change on re-valving the Trumpy suspension and go that way.
The other thing is take the MTS for a test ride (if you're permitted) and evaluate the differences. I found somewhere on the web a maxi enduro test between the Triumph, MTS, V-Strom and something else. The Trumpy got top marks cause it is newer than the unchanged Multi.
Another OR, wait for the NEW Multi to be released to the public from Milano expo in November.
Cheers,
Steve
