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.

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.

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

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

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
