The second part of the AXI part number is the length of the stator. So that means the 5325 has a 25mm stator.

Looks like the 5325/24 is available now. Will be interesting to see what people think of it after some use.

I think we need to be mindful of weight comparisons between motors. My AXI 5330/F3A weighs 670grams with adaptors and plugs etc. Take a close look at what the Hacker or Neu motors weigh when you include the adaptor, plugs and mounting brackets etc. There's not as much in it as you might be led to believe. The mounting method for an out-runner is far simpler and lighter than an in-runner... Just my two cents worth...
