I probably average 30-35 mph on my TW. I always just explore backroads at 40-50 mph, but it would be lower cause sometimes I go through 25 mph zones through town and neighborhood areas.
Now on my 919 I probably average 60-70 even with 25-35 mph zones thrown in There's nothing like cruising a smooth wide open country road at 75-85 mph with some 100-120 mph bursts on the straights. No driveways/side road for idiots to pull out of, virtually no way to get "busted", beautiful scenery and a nice quick fun pace. Ahhhhhh....people that don't ride don't know how much they're missing!
