Addicted to Super Cubs

My Cub - a CT110 Hunter Cub / Postie Bike / 'the World's Greatest Farm Bike' -- see episode 6, 21:00 of the Super Cub Anime for details of the same model bike that Reiko talks about.

..which I've ridden around Australia a few times..

..clocked the odometer..

..and got to the same mileage as seen of the OP. :D

Addicted to Details: In the light novel, the CT110 Reiko gets is the CT110AG, the Australian/New Zealand Agricultral Model CT110--which keeps the original Japanese style of odometer but also the dual-range transmission (there's a switchable additional reduction gear off the engine) and is very likely using a 6 volt system. However in the Anime, Reiko gets a CT110X, the custom-made Australian model, which is clear from a lot of small details (odometer, kickstands, indicators, swingarm, etc.) in the 3DCG.

Reiko's seiyuu, Ayaka Nanase, went out and bought a CT110AG after the show was produced! See it in her timeline! https://x.com/_ayaka_nanase/media .. Her bike is the road-registerable CT110AG that was produced for a limited time during 2006-2007.
