Do the Napoleons fit straight-away? Does the Bullet UCE come with a 1" bar? Any carrier you guys recommend to buy these from?
The Napoleons fit straightaway. You can use the bolts from the mirrors to go through the bar end weights, although I would suggest getting longer bolts.
I got mine off Ebay. Be sure to look for the Baron brand, there are others out there that can be a bit inferior.
The bars are 7/8", which is common for most motorcycles in the world, except Harleys, and maybe some other big cruisers
