I wouldn't want to cruise steadily at 3500, but it won't hurt the motor.
Going with a 24/55 setup you'll see 3244 rpms at 80.
About what I'm seeing at 80, reads just off the 3200 tick on the tach.
That being said owning a litre + class motorcycle means you can do 100mph + when safe, and anything taller than 24/55 will severely limit these speeds for sheer comfort as that motor does feel ungainly over 4000rpm substained.
Like I said prior, I feel the best all around setup for the 2006+ bikes is 25/55 for many reasons, unless you are a semi or professional stunter.
