My bone stock 06 Ultra has been to 102 (checked by GPS). I don't remember what the speedometer said, but it was low.I had more throttle left, but didn't see any need to find out my top limit. Haven't been to 90 since.
Keep in mind I just got my SERT installed, would this have anything to do with the rev limiter setting on the ECM? Could it be different on all of these after the SERT has been installed, or is the rev limiter a pretty much 'constant' setting?
My 08UC is stock as far as engine is concerned and it surprised my when I was trying to catch up to my buddy one day with the wifey 2 up. No downshift, etc, just rolled on the throttle in 6th gear and itwent from 75 to 95 real smooth and quick like. I normally dont drive that fast but I had plenty of throttle left.
07 stock could roll ok up to 95-100 ,,after stage I it seems to get there with better responce like im rideing it to 95 not that sail boat feeling and maybe higher but have not pushed it.
2008 ULTRA Classic bone stock besides the S.E slip ons,cruises at 80 with two up like a sewing machine,been too 105 with plenty more to go,no shakes,no wobbles,rides like a cadillac on two wheels.
