I have 22,000 miles on my 97 daytona engine. It runs as strong as the day it was new.
Seriously, sportbike engines last a LONG time. People have been known to get 100k out of them.
Change the oil on a regular basis, do the recommended service, and it'll last indefinitely.
The ONLY instances i have ever heard of that involve triumph engines dying is from a wreck or from running them without enough oil.
Also- it'll shorten the life if you don't change the oil often enough, but i have NEVER heard of a Triumph Triple just going bad.
I would not give it a second thought.
