Yes it had the factory solid wheels , he didn’t have any cross winds at the time he clocked those speedsDoes he have one of the models with solid wheels? Those wheels are gorgeous, but having owned a cruiser with almost solid wheels and one without, there is a huge handling difference with solid wheels in heavy crosswinds, at least on the lighter-weight cruisers, despite all the claims to the contrary, so it makes me wonder if there's any effect at your relative's 125mph-ish speed.
And do you know if the dealer re-flashes the ECU when you buy Screamin' Eagle upgrades?
Shoot, I have no plans to buy a FatBoy, but I just find it all interesting. ?
He bought the bike new , they did the P/D for him , he went in and saw it , then they wheeled it back into the shop and pulled the engine apart.
Cases were milled , CNC heads , upgraded injectors , throttle body and flash tuner. They dyno’d it and he still had two years warranty
