Hi guys, hope I'm posting this in the right section, didn't think the CG would classify as a classic haha. Basically I've bought my first bike to run around on while I complete direct access, it's a 1998 Honda CG 125. My main question is about the gearbox, it's reversed with neutral and then 4 gears down. I can't find much about this online and was wondering if I can do anything to swap this around to even just four up? I've attached a picture of what the bike looks like if that helps identify whether it was Brazilian built or not. The parts do say made in Japan but doubt that means a lot. Thanks for any help!
