Adding Harley TPMS to Tri-Glide

[Phrogg]

So I know that it’s been possible to add TPMS to the 2 wheel bikes by adding sensors and doing a flash. Has anyone done that for a trike? I’m being told that there isn’t a setting for 3 wheels in the digital tech.

Thinking I can just put in the sensors and flash it.

TG TPMS

The CVO TG comes stock with TPMS. From what I have gathered to get it on a "Regular" TG you need to get new Wheels that can hold the HD TPMS Sensors. "Regular" TG's Wheels are not equipt to adapt the wheel sensors. This is what I was to understand from the HD dealer. The Instrument cluster would then pick up the TPMS. Not sure it it would have to be flashed but you are probably right.

Lots of guys are opting for after market TPMS valve stem caps. There are a few out there on the market.

I'm not sure how to add it but it was supposed to be included in the RDRS system except on trikes. I was disappointed it was not on my 2021 Tri. Just another example of Harley cutting corners to save a buck. Good luck on getting it to work.

I am not sure if the stock front wheel is even capable of taking the tpms sensor. H-D sells a retrofit kit for 2020 and up two wheelers but the stock front wheel on the TGs is not listed as compatible. Ditto on the rear wheels. The CVO TG does have tpms but the wheels are totally different.

I have it on my cvo and would not miss it. I like to run the back tires lower than spec so I constantly get a low tire pressure message.

Agree. Had a 2017 Freewheeler and a 2021 Triglide Ultra. Ran both rear tires at 22. Now have a 21 CVO and those tires at 22 lbs will trip the alarm. Have been okay at 23. Wonder if anyone put regular size tires on a CVO?

I'm also interested on adding TPMS on my 2017 trike, any suggestions on after market? thanks

Like Yogi once said that he didn’t say: You can observe a lot just by looking…

Like manually checking tire pressures it gives you a chance to look at everything going on with your tires and undercarriage which sometimes is a good thing to observe …

If I have a low tire on the rear of my trike, it will pull to the low side. Maybe cause it's heavier than a triglide.:Shrug:

What happened's when both are low......:laugh:.....

IMO, TPMS is just 1 more gadget I do not need

Most of these systems are calibrated to warn @ 25% below manufacturer recommendations

Most all that I have talked with already are running below these settings, so my question is how low are we willing to go before this system becomes an aggravation?

Hypothetically speaking…Let’s just say The warning light triggers at 28 pounds but you wanna ride at 25 pounds so do you ignore the light ..And what if the psi should drop below 25 how would you know unless you periodically bend down and check the pressure with an air gauge yourself ??

That is what an experienced rider IMO should already know, check the PSI with a good gauge regularly , we are becoming too nanny IMO depending on things to do for us what we should do out of common sense

I can most times tell by kicking my tires if they are low This comes from training @ a young age by my teacher, my dad a self taught diesel mechanic( he held certifications from Detroit diesel a s well as Perkins and Mack )

Similar to how I check our 100 pound Propane tanks at camp’ I take a hammer and tap from top to bottom and I can tell how low they are… The truckers use to check Tractor trailer tires with A heavy piece of wood by banging on the side of the tire ..

Exactly, there is no doubt what that sounds like:clapping:

Very interesting thread - I found this because I had a similar question. In my case, I have a 2021 Harly Ultra. This came with TMPS - and worked fine.

I have since converted the bike to a trike, CSC conversion. Now, the front TMPS still works however, since there is no TMPS in the rear, whenever I start the bike, it says, low rear pressure. Plus, when I clear that, the light stays on.

My bike goes in for service on Monday. I asked the dealer is they could deactivate the TMPS - will find out later.

Having said all of this, I am not mechanically inclined. So, it sounds like - if my wheels are TMPS compatible, they can add the sensors and all might work again.

The other thing I read here is some guys went to alternate sensors. So, are those the ones that are added to the valve stem - and how did they work. Were you able to tie those into the Harley system?

Thanks

Better to invest in a quality tire gauge. Milton makes a very good tire gauge. Made in USA. Under 20.00 bucks I think.If access is a problem HD sells an extension and it isnt a $100.00

For me. the tire gauge is not the issue - I have that light on - this is why I want it disabled.

Was at the dealership today - talked to the service manager. He told me he didn't think we could put TMPS on the converted unit - the bike is set for 2 wheels. I asked about the TMPS on the TriGlide CVO - said he would check on this.

Then asked him to disable it. Said he added TMPS to his person bike and it worked. So, given this, he doesn't see a reason as to why he can't disable the TMPOS.

Will psot what we discover once my bike is done

I had one that I did I took the rear sensor out of the original rear wheel and put it on one of the rear wheels of the trike, it shut the light off , still had two wheel TPMS . It shut the light off .

Road Dog - thanks so much. If this works, I would be happy to try this process. I still have my original wheel and tire - all mounted and in my garage.

So, do I have to have the exact TMPS that is in that old wheel or, can I simply buy a new one any mount it in one of the trike wheels?

Some others here say that I would need a special wheel that is equipped to handle TMPS.

Since my dealer services trikes, I am pretty certain that they can dismount the tire on my trike. Naturally, they can dismount my old bike tire.

Hopefully I can just buy a new TMPS sensor and take it to some place like Discount tire and have it installed. So, once you had it put in your trike tire, did you have to do anything else and, did the system find it automatically?

Thanks

You need to use your old one, out of your two wheel rear wheel you will have to buy a valve stem discount tire should have the valve stem . should be no problem

Sounds pretty simple - then I wondered, if this is so simply, they why don't the conversion companies like CSC RoadSmith, MotorTrike install TMPS in the wheels they put on. Better still, why don't they tell you to install the one from your front wheel into the rear wheel of the trike.

So, I called my discount tire. Asked them is I needed an exact match for TMPS, he said no. Then I asked if he would put a TMPS sensor in my trike rear - he said, we don't work on motorcycles. I followed to say that its a car tire - still he said, they don't work on motorcycles. However, if I just brought him the tire and wheel, he could look at it and take the tire off and mount the TMPS sensor.

Well, I am at a loss - but, want to be able to ride so will get the work done I need and ride this season. Perhaps when the season is over and the dealer is not busy, I can take the bike to him with the old tire. See if he will make the exchange and put the old sensor in the rear trike tire.

I don't mind purchasing a new sensor from the Harley dealer if this would work. Do you know if it would? Seems to me it would work. Why would that be any different than replacing the rear tire and sensor if something happened to it.

 

[cycle7447]

OK, for giggles, I decided to try something.

When I start my bike, the tire system comes up saying I need air - OK, I get that - no TPMS on the trike tire. When I press the button, it says the pressure is 36 and low. If I remember, when I was at the dealership, it read as if there was no TMPS there.

Then I realized - when I am at home I have the old tire in my garage. So, I went over to that, checked the pressure and it read 36. My tire calls for 40 so, I took my little pump and added up to 45PSI in that tire.

Started the bike - and guess what - there was no indication that I had a low tire pressure. So, I went to the info, pushed the button and it read 45 - just like I had filled the tire.

Now the tire light is still on but, as I recall, that does not go off until you start to ride. All of this is interesting - lets see where we can go from here

You can buy a new one from Harley for a Tri Glide have it installed in your rear wheel then it will have to be programed to your bike, any new tpms for any car truck bus what ever has to be programed to that vehicle

Ok the wheel is in the garage next to the trike you put air in the tire your trike reads that, Put that sensor in your trike tire the trike will read it , Your done .

Thanks - the trike is going in for a few things today. Adding XM radio, having a front fender light and trim installed - plus the big one, I have no clutch on a bike with 821 miles.

Back to the TMPS - I will share what I learned here with my dealer - see if they have a TriGlide TMPS and, "IF" they will install it in my tire.

Reading a little more about TMPS, sounds like they are also tire size dependent. My trike tire is a 17. So, will have tons of questions for the dealer.

Again, if this is so easy, why haven't the trike manufacturers simply put TMPS in these wheels

Whats up with the clutch ? When they trike it they must have pulled the outer primary & inner primary and clutch to change the swing arm ? On the TPMS I checked on a chevy pickup They come with 17',18",20" & 22" wheels it says they all take the same sensor , I checked Ronnies HD on line it said a harley tri glide rear tire sensor was over $200. Man you can buy car sensors for $25.00 . I would take your rear wheel to the harley shop have them remove your sensor go to a independent automotive shop that has a tire machine and have them install it in your trike rear tire if it dont work so you wasted another $ 75.00 . Thats just my Deranged Thinking :xzqxz:

Thanks for your response about the clutch. I talked to the installer and they said they did not make any clutch adjustments. i know they pulled the primary - had to do that to put the new belts on.

Installer said he has never had this kind of as problem with the clutch not working after an install - been doing trikes since 2003. So, my dealer has it now and installer says they will pay the price to fix whatever it is.

Am liking the idea about taking my wheel to the dealership and removing the sensor.

Thanks guys - you have been a big help. Will let you know more about the clutch when I get the bike back - hopefully tomorrow

For me - I just want it done right. Have a new bike, like I said 821 miles on it. Couldn't ride last year because of surgery. So, am hopeful that this can be fixed and I will be comfortable with the bike on long trips.

Your 21 model has 2 clutch adjustments, the clutch basket ( same as in the past with cable pull clutch) and the new spring assist ( POS IMO) cable adjuster

They are cheaply made and are going to break, it is just a matter of time

Here is a link to a very good looking fix

Hopefully it is just an adjustment problem

Im pretty sure HD dosnt mfg those sensors. If theres a part# or mfg code on it take down to NAPA and see if they can cross reference it.
