Why don't you get another 400 miles on the clock and get the first service over and then you will be able to be a bit more liberal with the throttle. I can quite hapily cruise at 85mph on my Ten with the panniers fully loaded and still get a good 200 miles before reserve flashes. 70 will be soooo much more comfortable and you will be able to see the scenery.

Cheers and have a good time. Steve
