If you don't want to take the bike apart measure the diameter of the spacers. Looking at my bike and a 2015 Ultimate picture it seems like they use the same oversized ones so that should be a good indicator.
Looked at my bike and it actually says 1 1/4 on the stem 🙈. I'll buy it, literally perfect size. I can pick it up tomorrow if you're around? I'm going for a ride in the morning but could pick up in the afternoon?
No problem. SE8 4AU.
