Anyone know for sure if the Opmid speedometer/multimeter is compatible with the new 2022 Honda CT125 Trail Bike? Can't seem to find a 100% true answer anywhere else.

It would be extremely, extremely strange if it no longer worked for the 2022 model. As far as I'm aware, there's no updates to the model from the 2021 version other than colors in non-US markets. Hopefully that will help with your mod purchases.

The stock Honda Trail 125 speedo is fine except it could use a gear indicator, I have a '21 S Cub 125 that has gear indication, its nice to have, am going to add a separate Shift Position Indicator from webike. Thats the only change it needs

There's a lot of things the stock Honda speedo could use some love in.

I bought one for 3 reasons:
- Brighter display that's easier to read in bright daylight. Mine's nearly invisible under certain riding conditions. It's ok during nighttime but terrible during daylight.
- More accurate readout, particularly if you change the sprockets or tire sizes. My stock one is off by ~6%.
- A CLOCK. SO I KNOW WHAT TIME IT IS. Crazy that Honda didn't include a clock on this.

I don't think the gear indicator will work very well for most of the situations where I would want to use it, based on a rough guess of how it works. But that will be kind of nice as well to no longer be guessing if I really did make that 4th gear shift.

I haven't gotten around to installing my OPMID yet, but I bought it for similar reasons. My main complaint with the OE speedometer is that it's hard to see what's on the screen half the time in sunny Colorado. Aside from that I am looking forward to having a clock, being able to dial in the speedometer readout, and having a tachometer.

I too am in Colorado and having the Opmid has been a blessing! Also interesting to see the temps especially with our hills lol!

Sneaky? have you figured out how to get rid of the dual green blinking lights once the CT125 is up to a certain speed? drives me crazy - i glance down and i think i forgot to turn the turn signal off once again. Clue us in if you know? Thanks

Thanks for the reply Sneaky -- got it ordered, and delivered and installed, now just playing with the settings to make all those flashing indicators go away once i hit 47mph.... only one i can't figure out is the twin Green Indicators which in the photos in the install papers says is the Shift Indicator, the center works when its time to shift but when i get up to 47mph, the indicators on each side of the center indicator begin flashing green on and off, on and off, untill the speed drops below 47mph... i have no clue what that means.

Silly question, might be obvious, but:

When watching some YouTube instructional install videos on the OPMID, during setup, you manually enter in the miles for the odometer so the OPMID to match your actual miles.

What happens if I want tor return it to stock and put the old speedo back on (selling the bike or what have you)? Will the old speedo still be at the last reading before it was unplugged, or is there some memory setting in the ECM that actually knows the mileage? What's to stop someone from just resetting the mileage on an OPMID again and manually lowering it if they go to sell the bike?

The odometer reading is stored in the instrument gauge. If you were to install the OPMID, put on some miles, and then swap it back to the OEM instrument gauge then depending on your location you may have a legal obligation to disclose those changes to the buyer and mark it on the bike's certificate of title. This is very common for motorcycles, and not just Honda, other brands store mileage in the instruments as well. It adds to the reasons why it's important to fully inspect the wear on a used bike and ask for any service history if you have concerns around mileage. Many of these bikes are likely going to remain low mileage bikes like so many of the old CTs were, but there will definitely be some ridden into the ground like Posties.

Got it, thanks for the clarifications.

I guess the only real way I'll never have to worry one way or the other, is just keep my Trail forever. Well that was easy.

Mine does the same thing.
Planning on calling Hard Racing to ask about it but haven't done so yet.

a ridge overlooking Lake Guntersville, AL.
Was in Telico Plains Monday riding and my OPMID went bat shit crazy. Started throwing max rpm symbol bars and flashing over rev two greens and red light on bottom. Engine seemed fine at the time .............. but............. Tuesday took off from camp ground with same symptoms and it lost ability to sense what gear it was in ............. then............... engine started to cut out/stumble at high speed, not surge.... then 20 miles later it began to lose power.... then 5 miles after that it started to quit. Would start up and run but as soon as you would take off and accelerate it would quit again. After numerous attempts to keep running it would not start again. Later back in campground it would start and quit. Yes Johnny you can tow a CT125 in the mountains but its a sporty course. Got to use crash bar to retain steering and try to stay off set with NO slack occurring. Front brake gave up after 20 miles? Had to use rear. Front came back a little later. Was 98 degrees. Companion CT125 proved they are indeed a little red donkey as it pulled the broken one with a 220lb rider up and down Hwy 68 from the Ocoee river area. Yes it wasn't happy and over heat was flashing now and then but that was flashing any way all day going up hills due to heat. Now got to take bike to dealer and figure out what happened with broken one? Electronic problem? ECU me thinks and was progressive?

On this bike i certainly do not get it, at all either. Don't get me wrong, i have spent (way) more on high end stepper tachs/speedometers and such for my other bikes, but who really needs a gear indcator on a 4 speed bike and a tach for a motor with a rev limiter thats very, very very conservative. .02

Hey gents. Can anyone recommend a simple add-on tach like this one compatible with the 125? I like this set up think I'll be doing the same thing.

This is the one pictured, though it's discontinued: https://japan.webike.net/products/24577163.html
Any tachometer that can be set for single-cylinder use should work. Expect that it may "lag".

Takegawa sell some add-on sweeping needle analog tach kits for the CT125.
Pay attention to the range on them, you probably don't want to buy a 16k RPM gauge and have the needle barely move on it, that could be hard to read.
