Not on our Ruhmores cut off at 90 MPH on our 07 and 08 UC it would cut off at 85 MPH and realistically it was 81 and 82 MPH because both speedometer were in accurate.
I set the cruise on 90 yesterday...and stayed there for over an hour. A big chunk of I-15 here in Southern Utah is 80mph speed limit and unless you are going 90, they will run over you. It was turning about 3500 rpm and was so stable it was unreal. The new Rushmore will run with the big boys...NO PROBLEM. It's no Hyabusa, don't get me wrong, but you could HONESTLY run 90-100 as long as you want.
I pegged mine a couple times and that's enough for me. First time was my ride from Erie to home when it was brand new, I never believed in the "baby it" break-in routine and never will. Second time was a little easier after I put the tuner and exhaust on and still running like a champ 8,333 miles later. I rarely beat my bikes or cars except for break-in, but I always punish anything I buy new and always ended up with good runners and no problems that way so why change. If it is going to break I want it to happen with a fresh warranty when it's stock and brand new, not 2 years later after modding it.
I have been up to around 110, but after my foot flew off the floorboard/highway peg (heel toe combo) and touched the ground briefly at about 105 I don't go that fast anymore lol.
That put an end to that didn't it.... glad you made it out.
120mph when my girlfriend passed me in 3rg gear and ran hers up to about 160. Oh, yeah, she was on her R1 .It seems the sweet spot is 90-95mph on the Rushmore's . It will do it all day long!!
