For what it's worth Zero sells a "dirt bike seat", I forget exactly what they call it but can get the part number if you like.  It's the flat, non-contoured seat from the 2013 model.  It has more padding and is a bit taller.  Drop on replacement, just has the old Zero logo.

They are definitely confusing, I see numbers thrown around that don't seem to match the log parser from the hundreds of files uploaded to it.

When I first got my 2014 my firmware, according to the log parser, was something like 44.  It's been upgraded a few times - 47, 49, 52, 53, 54 now.  These numbers make sense and are sequential.

For the most part, people with 2014-2016's seem to be in the same range, regardless of model or year.

But the newest bikes people are throwing out numbers much different from that series.  Nobody has uploaded a 2018 log to the online parser utility yet, that I can tell, so I wonder if they're seeing it in the Zero app and if that is reporting the same number as the parser.

I should be picking up my 2018 FX this weekend and will piece it together.  I'll look in the Zero app and upload a log and compare.

The link above to the latest firmwares is current.  I think 54 is the latest MBB version for 2014-2016 or maybe even 2017.  I just got it a week or two ago.

Note that I'm only speaking of MBB versions.  BMS versions on my bike are lower, it was just upgraded from 27 to 31, supposedly 31 being the latest BMS from Zero.

is there a way to save the files of perfectly good bikes so that we have a baseline to work from

I'm hanging on to all the results that parsed OK.  I don't know of any way we can tell what's good from bad, there's a ton of data in them, but we can at least have them for comparison.

I'm glad it's been useful!

I'm certainly no expert at reading / debugging the logs, just trying to get people easier access to them without the technical hurdles.
