In my experience, all of my boxers have been disappointing beyond normal highway speed. The worst was my R1100S, which vibrated annoyingly above 70-75 mph. That's the primary reason I sold it, which was a shame because it handled great and had all the elements to be a great sporty sport-tourer. My R850R wasn't as bad at those speeds, perhaps due to its lower displacement (same stroke as the 1100 but with a smaller bore), but nothing to be proud of. My former '08 RT and current '15 RT were better, but nowhere as smooth as a big inline-4, and nowhere close to my CB. By point of comparison, both my former Ducati 620 Monster (transverse L twin) and Moto Guzzi V7 (longitudinal V twin) were pure velvet at higher speeds. A little recalcitrant down low, but absolutely wonderful at 5000+ rpm.
