Seattle, climbing I-5 southbound hill from I-405: accelerating through 83 (surprised me when I looked!!), slowed by traffic.
Northbound I-5 from I-405, ran effortlessly 75-80 (depending on traffic) through rolling hills, hit 85 climbing when possible though slowed by traffic. (downhill doesn't count)
Climbing 509 hill from 1st Ave. bridge: 75-80, limited by traffic.
On ramp, use 4th gear to 70-73 before shifting to 5th.
Bike feels like it'll run 70-80 all day and like it.
65-70, vibration negligible.
Jus' sayin'. Don't underestimate this engine
