Beast, I run a GTR1400 Kawasaki and it recommends oil, filter and diff oil changes @ 7500 miles. I'm around 12K miles and the "Connie" runs bloody good. Cheers, Mate.
The final drive fluid looked a bit cloudy; maybe some moisture got in? That happened a few times to me on the old GSA. I did my FD every 6k with the engine oil only because I had it off road and in water crossings so much and because BMW FD's have a high failure rate. I was always pleased though when I drained it and it was still golden yellow :) Also, I tried to use a torque wrench whenever I could given I tended to over-torque most of the time. Great vid!
Wandering Beast My Triumph also calls for 10k oil changes, but even the shop tech said that's too many! So I do it every 5k. As for final drive, Triumph calls for a drive fluid change at 500 miles (first service) then NEVER AGAIN! Needless to say, mine gets changed every other oil change. I know Yammies are good, but I wouldn't push it.
