A little circle of electrical tape over the light fixes that!

Anybody in the states selling the stock gearing sprockets with a better chain? All I'm seeing is UK stuff with 35 bucks shipping on ebay.
You can buy OEM sprockets through any of the sites that carry OEM parts, and then buy a sealed chain through a vendor such as sprocketcenter.com . They also sell aftermarket sprockets in OEM sizes.

almost no personally owned gps indicates in nMPH. Only ones for boats would come that way by default. If you look at your phone while its mounted on the bike, or a bike/MTB type system, it's regular old MPH, at least in the US and most of CA and Mex. European sold ones will indicate KPH by default.Are you sure? When my speedo says 55 my GPS says 52. So if that is 52 NPH that means my CT goes just under 60 MPHAs nice as that would be it ain't true. Not all GPS indicate speed in knots, the Garmen is either you can change it.
Correct. OEM parts for the CT125 are 428.
So odd they use different sizes. Maybe the bigger 428 is to give it more longevity offroad?
I found the stock JT part number for the front
I found the stock JT part number for the front
JTF273 plus .x for whatever tooth size
but nothing for the right part numbers for the rear. Not even the JT site has the rear listed. Anyone have the part numers or PDF of them?If you have a 2021-2022 JA55 Honda Trail 125 then you can run JTR269 on the rear. 39T is the standard rear tooth count for the 2021-2022. You will find that the stock nuts for attaching the rear sprocket don't sit flush on this aftermarket sprocket. One solution is to use four M8 nuts with a 13mm head. See this visualized here:

I bought the nylock nuts that I am using here:

If you are aren't changing the rear sprocket size, you could also just run a replacement OEM sprocket to keep things simple. P/N: 41200-K2E-T00 , can be found online from many sites that sell OEM parts.

Thank you.
Glad to know that. I'll be getting a better chain too.

If you're starting off with the 108 link chain, moving the rear wheel forward ~15mm should be enough to account for the larger number of teeth if you're just looking to try it. If that's a reasonable option, consider giving it a shot with the old chain to get an idea of whether you like the gearing or not before you cut the new one.

If you have an angle grinder, it will work just fine for removing links from a longer chain. Keep in mind that it's likely to damage the removed outer plate where you're grinding, so measure twice, mark, and grind once.

Take the number of rear sprocket and divide by number of front sprocket. That will tell you the ratio. 47 tooth divided by 13 tooth front means for every 3.6 turns of front sprocket the rear will turn once. The speedometer will be slightly off unless you go up on tire size. 244 Shinko 3/0s will actually run faster than the speedometer reads,and the bike will also be going faster in your case,if you can wind it up fast enough. Unless you live in south Florida,I doubt you will.
