[@gustavinho86]

Just installed it on my new 2020 grom! Easier than it looks. Had no problem or troubles ! Excellent product. TST is the real deal ...

[@ismailbergum7204]

Can you tell me how you moved the tip sensor? Because mine has some sort og seat lock thingnin the way

[@NawiboJ]

Questions three years ago ,,,to late to answer...but using open end 10mm wrench helps unbolt the tip sensor...then move it to the middle area near the battery with the plate...had to drill two holes for the screws..and run the wire to it..

[@847concepts5]

Thank you, and great job to the guys at TST! Enjoying my under tail system that they installed for me in this video. Clean install and looks great!

[@TSTindustries]

Thanks T.

[@jordanwillie6726]

@Isaiah Musa thanks so much for your reply. I got to the site thru google and Im trying it out now. I see it takes quite some time so I will reply here later with my results.

[@NawiboJ]

Just finished installing your tst integrated taillight...also got you license plate bracket and light....I watched your video a few times and was nervous about the wiring ..tip sendir plate and razor hacksaw parts.....I'm a machinist which helps, but not much of a mechanic.. Anyway..took around three hours...but it all works ,, brake light .blinkers and license plate light,, 👍 and it looks better then stock 👍 I have a 2019 Grom I bought a few weeks ago...if I can install it then anyone reading this can..😂 Main tools needed...beer...10 mm socket with extension...4,mm Allen wrench..razor to cut plastic..hacksaw...although could use just razor...Phillips screwdriver...1/8 inch drill for tip sensor bracket...and patience with the razor...follow the same cuts and it eventually cuts thru good.... I installed the license plate bracket backwards but it was easy to flip it when I noticed... For a little less then 200 dollars it's amazing compared to stock ...I bought the integrated lights...license holder and lights at the same time...and a relay ... Wish I could add pictures...

[@KelleyKAM]

The moment y'all have a sale, I'm gonna get this! Looks great!

[@Adventuresouthlife]

Just finished installing the light. Everything worked perfect. The only thing I would recommend is go ahead and install the license plate bracket when you install the plate. It's one less step of unscrewing and screwing again.

[@TSTindustries]

This is true but we had to split up the video so that our audience wouldn't have to sift through an hour of footage.

[@michaelmcghee1789]

Great video I really enjoyed it. Good job guys.

[@amyclick6214]

Really appreciate the detailed video, made install super easy. Love how sleek my lil’ G looks! It’s so sweet that now I want to mod out the R3 😁

[@TSTindustries]

Do it!

[@nannychips]

Thank you. And when will the video be available TSTindustries, about how to do it?

[@mattc420]

How are you getting the brake lights to get brighter when you press the brake lever? I done this install perfect and double checked everything several times. It says nothing about how to install anything that makes the brake light up under press load??! This is kind of aajor safety concern. Can seomeone help me quick?

[@redlinethin]

I love ur Grom mod tutorials, more please!

[@TSTindustries]

We will have more at some point...I promise.

[@Adventuresouthlife]

Great video. My daughters taillight shipped yesterday. Looking forward to the project.

[@TSTindustries]

We can't wait to hear your feedback. Cheers!

[@TSTindustries]

How did you guys make out with the kit?

[@Adventuresouthlife]

TSTindustries super easy to install. Had it done in an hour taking my time. The light looks sweet. We even got a sweet swag bag from TST. Thank you thank you.

[@TSTindustries]

Right on...I'm so glad you guys are enjoying our parts.

[@monarch29balisongs]

Ordered my kit yesterday, thanks TST!

[@TSTindustries]

You're welcome. I hope you enjoy it as much as we enjoyed designing and manufacturing it.

[@Nelluch390]

Could you please add a link to the oem undertail plastic that you cut? I made a mistake. Need a stock replacement.

[@TSTindustries]

We may still have some in stock. For a while we were stocking them to help customers out. Our customer service guys would be the ones to talk to. Otherwise MrCycles.com or Partzilla is a good source. You just punch in your year, model info and look at the fiche to select the part you need.

[@rylanlara5416]

followed every step and get to the part where you test your lights, didn’t turn on, does that have anything to do with the relay? i bought a different one from NAPA not the one from TST, would that make a difference?

[@TSTindustries]

Nah, the relay is on the signaling circuit nothing your brake and running light.

[@AidanDoesGaming]

Does the entire package come with the plastic part for the led light to fit in?

[@TSTindustries]

Do you mean the undertail? Yes, of course then...that is the main part of the package. If you take a look at the product page on our website you can see the "What's In the Box" photos to get a visual understanding of what the kit comes with. Here is the link: tstindustries.com/TST-Undertail-Integrated-Tail-Light-System-Honda-Grom-2017.html?KZbin&YT_PRODUCTS&INT_install_video_part1

[@dcweber1]

When I step on the brake I don’t have a brake light. Is this normal for this install?

[@caliboyrider2152]

DeeCee Dubya I’m wondering the same thing

[@warrenpeas]

is the signal bright enough? hard to tell

[@TSTindustries]

Most people who buy this kit say that it is, but you can always add external pod signals

[@treyhorak]

Why don't I have a giant cavity under the front of my seat for the tip-over sensor? I don't know what to do now. Do I have to connect it?

[@TSTindustries]

It sounds like you may have an ABS model. If so, the link below should clear up any confusion. kzbin.info/www/bejne/gWW7YZ2Hm9dnfrc

[@treyhorak]

@@TSTindustries Thank you! I found that video after searching the comments. I bought the kit for the front and back. The tip-over sensor mount installation video for the ABS Groms wasn't included in the playlist for the kit. Again, thank you! Onto the front signals and the relay!

[@bretebaugh4912]

On the 2020 there is some serious hardware blocking the suggested tip sensor location. Any update? Is the tip sensor required?

[@TSTindustries]

Yes, the tip sensor is required. You cannot operate your bike without it unless you bypass it but we recommend against that because that is a safety device. I think the main thing you are seeing is the ABS pump there. This means that you have an ABS version of the bike. That rolled out in 2018 and we quickly reacted with an alternate relocation kit specific to that model variant. Please see this video and see if this will get you going: kzbin.info/www/bejne/gWW7YZ2Hm9dnfrc

[@bretebaugh4912]

TSTindustries got it, and the part included was for the 18+, great work!

[@sebastianbark9563]

TST still active? Are you able to wire it so that the tail light only works as a brake light and install external indicators? I know many people would be interested in this if you were to make a vid. integrated turn signals are illegal In some country's.

[@TSTindustries]

Simply do not plug in the signal plug from the tail light harness and you then retain only running and brake functions.

[@xlCHAPAlx]

Hello, I can’t find this fender eliminator kit for my 2018 on the Toce Website. Did you guys discontinue this kit?

[@TSTindustries]

Toce and TST are two separate companies. We are TST Industries and we still have the undertail / fender eliminator available. Please go to TSTindustries.com

[@MegaDante5]

What happens when you already have a fender eliminator? Put, it in the tst one?

[@TSTindustries]

I don't know what you have to be able to answer this question.

[@AveryRucker-to3el]

What do I do if my blinkers don’t flash at all? They just stay solid Amber.

[@TSTindustries]

You need our LED Flasher Relay.

[@TheOffroadn20]

Seems flimsy but really my only concern is water and couldn't really tell from the video but are there any seals around the light and under tail components to keep water out

[@TSTindustries]

Our system is designed to be more rigid and as weather resistant as the OEM components. There are plenty of gaps in the OE setup that will seep water in if you take your Grom on a scuba excursion.

[@mikemooch7719]

I just followed the video & installed the full kit. The tail light isn’t lighting up. The two connections are good. What could the issue be?

[@TSTindustries]

[@imadethislongcuz2]

[@Cameramanrob_]

What’s the “modifications” needed to be done to fit a subcage and a 12 bar?

[@TSTindustries]

Oh man....we have done a custom install like that once for Photogromer. Every different setup will require different custom steps and hardware. I unfortunately can't really be any more specific.

[@Knif3L03r]

impacktech has a 12 bar and subcage that should bolt straight on

[@mattc420]

I installed my smoked tails with the turn signals in them and now my brake pedal when it's pressed in, does not make my light come on anymore. Everything is plugged in as it should be. There's no extra wires or anything. Really bummed.

[@TSTindustries]

Please watch this video and follow the steps within it. kzbin.info/www/bejne/aXm6lYmLrqmJjrM

[@nannychips]

TSTindustries is there anyway y'all could make a video of how to install a subcage with this as well or at least describe how much more needs to be done to do it? Really want to purchase this but want to make sure the subcage fits. Thanks.

[@TSTindustries]

Absolutely. We will make a quick video on how you are able to do it. We recently just installed this set up on a good friend of ours bike, Photogromer. I'll attach the video he made as well, so you are able to see what it looks like: kzbin.info/www/bejne/q5K4op59jpyFitk

[@nannychips]

Ok thanks. I saw that video yesterday it looks sick. The tail light looks amazing period but just want to see how much more has to be done to fit the subcage. And the kevtek subcage was on his bike correct? And when will you guys be posting a video?

[@BRIDGECITYRIDER]

I just purchased this to fit with a Kev TeK subcage as well. Is there any modification needed to fit the subcage. It looks like the 4 holes are still exposed for the cage?

[@AlassaneLeno]

Does this work with the new 2022 grom?

No, the new Grom has vastly different tail parts. We already made a different undertail and taillight for the 22+ model. You can see our parts catalog at TSTindustries.com

No two sub cages are the same. We did a custom setup for Photogromer. He had some sort of a subcake and we were able to make appropriate spacers and modify the system to make it all work together.

@@TSTindustries (SAD FACE) You guys should make a sub-cage that works with it. I would defiantly buy it.

@@TSTindustries what did you use to make the spacers? Something I can buy from home Depot or something? Just ordered this undertail from you guys and have a 12 bar coming. I really want to make it work. Thanks

[@TSTindustries]

@@multicamchannel we drilled larger holes through the undertail to insert spacers made of aluminum round stock. The spacers were made to allow metal to metal connection between subcage and subframe. I think you may be able to get round stock or tube that will work for you at HD or Lowes. If you don't find what you need try McMaster.com . They will definitely have what you need.

[@drewhil23]

aww man I was told by photogromer that there was no cutting involved, kinda of disappointed. And definitely nervous to do this now!

[@Photogromer]

I must have been peeing when they cut, my bad. From what I saw it was pretty quickly installed. We spent more time welding on a tip on my stock exhaust than putting on the undertail lol. The end result is super clean, I've been ripping sketchy wheelies all week, it's solid. I had to cut for my KevTek subcage to fit when I first got that, I was kinda hesitant at first but it's pretty simple and hard to mess up if you take your time.

[@drewhil23]

Photogromer it's cool no prob think I'm going to purchase it anyway

[@TSTindustries]

You will be cutting a part that costs $15 brand new. If you somehow mess up it's not a lot of money to restore it. If you follow our video you should have good results.

The motodynamics one just seems safer especially because it automatically blinks the breaks for you

[@TSTindustries]

We actually design quite a few of our tail lights that have that feature already built-in. Unfortunately this particular light did not have enough room in the capsule for the programming functions to be installed. However, we are hoping to release a stand-alone unit next year that will enable the "strobe brake" function on virtually any tail light on the market. Stay tuned!
