With side bags and 42litre trunk stuffed, I took my '08 up to 164 indicated, w/ 158 indicated on the gps, and ran out of safe road before topping out (leo patrolled road in Va) was still pulling nicely around 8k in 5th, I'm sure it could have hit 10k, shifting int 6th it wouldn't pull hard, but still had legs left.
Same setup with bags on, and with momma, on an uphill at the Canaan Valley rally, we pulled 148 uphill pasing a truck / horse trailer combo, and it had plenty of steam left before the kidney punches from momma took effect....ouch.
Stone stock bike except I trimmed the muffler down 6" .
About a month and a half ago, hit 170 on a rural Ohio road, I could see for about 3 miles, and there was no traffic... I saw headlights in the rearview about a mile behind me, mehhhh. I backed it down, and about a mile or so later pulled off to take a picture for an ADV Tag o Rama shot, and while fiddling with my camera for the shot, a car slowed up coming in from behind.... yep, it was a State Trooper.... he rolled by about 25mph giving me the "stink eye", and then he began laughing and shaking his index finger at me in a "don't ever do that again on my road" manner...
