I avoid the Interstate whenever possible. Yes, the Burgman will go 100 mph and yes, I've had it over that, but so what? I ride my bike to enjoy the experience. I simply don't enjoy riding that fast. The wind noise, the buffeting, the greater effort needed to maintain situational awareness — all contribute to fatigue. If I was in that much of a hurry, I would be flying or driving a car.
We cruise between 55 and 65mph, normally on secondary highways or forestry service roads. On average, we cover 250 miles in a day. We try to stop every hour to rehydrate and refocus, have a bite to eat, or to take photos. We ride between 08:00 and 20:00 to avoid animals crossing the road, since wherever we ride, there are deer. We can go for ten or twelve hours without getting seriously tired. In the early days, before we knew better, we would "push it", trying to make distance. We didn't wear ear plugs or stop often enough, and we would end up cranky and exhausted after five or six or eight hours — no fun at all.
We just returned from a tour through the US, through Montana, Idaho, Oregon and Washington. The only time we were tempted to go fast was on US97, south from Bend, Oregon. That is positively, absolutely THE most boring road in Oregon, so there was the temptation to get it over with quickly. It was also the ONLY stretch of road where we saw police — one sheriff and two state troopers — over the entire 3200 miles of our trip. Maybe they know something we don't...
Anyway, if I wanted to go 90mph on a bike, I would have a Ninja or Hayabusa, not a Burgman. I would also be on a track.
