2016 Honda TRX500 …. model codes?

Looking through the 2016 Honda Sales brochure …. specifically for the TRX500 Foreman.
There is no mention of what model the ‘codes’ are for …. eg. FM1, FM5, etc.
I’ve been quoted a price on each of these models, but I’m unable to see what TRX500 they refer to.
Any clarification would be greatly appreciated.
