Here's info I got from Honda Motorbikes New Zealand when I inquired about the CT125 farm kit a while back.
The farm kit comes with a 13T front and 51T rear sprocket, 114 link chain. They said they don't do anything to compensate for speedometer and odometer misreading or ABS fault as "the farm kit is for off road use".
The center stand is removed for ground clearance and to prevent snagging.
Tyres used are Mitroc 70-100 17 FRONT M807 and Mitroc 2.75-17 REAR M897, but Shinko SR241 are also available for it.
Honda (NZ) have a full range of farm kit accessories available for the CT125, from Smith Attachments:
CT125 CENTRE PROTECTOR - $290
CT125 FRONT GUARD RISER BRKT - $60
CT125 FRONT CARRIER - $255
CT125 HANDLE BAR PROTECTOR - $110
CT125 HEADLIGHT GUARD - $180
Prices are NZD.
When I inquired with Smith Attachments they said the parts they make for it need to be purchased through Honda dealers in NZ (some ship internationally) as they do not sell those accessories direct to consumers.
My understanding is that it is optionally fitted with variations of these items after import to New Zealand, rather than literally fitted that way from the factory.
Another interesting farm kit to check out is the XRM125. It's another Cub type Honda but with a rear drum brake more similar to the modern Super Cub, or an older version of the Wave:
The XRM125 is your reliable, all-purpose farm bike. A new bike to the NZ market, the XRM125 delivers cost effective farm transport for everyone on farm with step through design for easy mounting and dismounting.
