We knew that we had a really cool opportunity to improve upon the Honda Grom when we first got a hold of it. After removing the fender and discovering the big space left behind, our team immediately started coming up with solutions. We knew that our design needed to look OEM, while being very clear that it's not. That led us to develop a sleek and super bright LED integrated tail light in combination with a precision made undertail closeout panel that's made out of injection molded ABS plastic that perfectly matches the rest of the OEM undertail panels. This kit provides a seamless and unique way of ditching the massive stock fender and extra weight that comes with it. Our exclusive LED integrated tail light comes in either smoked or clear and is completely plug-and-play, so no messing with harness converters or wire splitters during install. And to enable further personalization, we offer three different license plate mounting brackets, enabling you to mount your plate in the high "stock" location or a low "tucked" position.

INSTALLATION NOTE: This kit requires the relocation of the tip sensor and some trimming of the subtray. Even with that though, the install process is pretty straight forward. And of course, we've got your back with a super-thorough installation video where you can watch Bart walk you through the process step-by-step. Even without mechanical experience, the install isn't difficult or overly complicated.

NON U.S. BUYERS: Our fixed bracket is designed for U.S. plates and fits a hole spacing of 5 to 6.1 inches with 5mm hardware, while the adjustable bracket fits a hole spacing of 5.2 to 6.29 inches with 5mm hardware. It is your responsibility to verify fitment before making your purchase.

LICENSE PLATE BRACKET: Have a Toce Exhaust (which includes a Toce specific bracket) or use your Grom on the track and don't want to include a license plate bracket? We have you covered. By selecting "No Thank You" in the License Plate Mounting Option you can opt out of recieving a plate bracket and save a few bucks. We only recommend this if you do not wish to ever change your exhaust setup or you ride exclusively on the track.

FLASH RATE: Want a quick plug-and-play solution to turn signal hyperflash without wiring in the optional Load Balancing Resistors? Check out our TST LED Flasher Relay. If you don't already have one installed on your bike and don't want to mess with wiring, save yourself some time on installation and money at checkout by using the Buy Together option to receive a special bundled discount.

I received this last night and installed it in about 1.5 hours. I thought It would be quicker, but that was only because I figured I could keep pace with the instructional video. I will be honest, if it wasn't for the superior customer service I've experienced with TST i would not have given this 5 stars. It is was a rather frustrating process at times and much of it seems like there could be an easier way. With that said, I am the consumer and the TST staff are the experts. I trust they made this as easy and quick as possible. I have 2 groms. I will be buying another one for my second grom now. Good job to the TST guys.

Advantages: Great fit/look
Instructional video

Disadvantages: If you don't have the tools around you will need to acquire them for the job.

May take longer than you expect.

The plastic is thin which makes it hard to slide on a couple of clips during the process that is required. I was worried I would crack the plastic.

So I ordered this undertail fender eliminator kit for my 17 grom. The quality was as expected. It was fairly easy to install following the detailed installation video. It looks good, works good. My only problem was that they sent the wrong size lock nuts for the bolts that tie down the undertail base. I had to run to the hardware store to buy the right size lock nuts. It's no big deal, it happens. I wasn't going to wait for tst to send me the right size nuts which I'm sure they would've. I had my bike all torn apart and just wanted to get it back together. Over all I am extremely happy with this product. Would recommend.

Preordered the kit and just installed on the evening of the 4th of July. When I rolled it out of my living room and out to the parking lot and instantly it got a lot of attention. By far the best looking tail section at the stunt spot. Install was super easy, did the relay, signals, and undertail with integrated light all in one shot. Maybe took 2 hours tops and that's with my 7 month old trying to eat my bike. Totally worth every penny.

Advantages: Looks amazing, easy install. Smiles per dollars is about 10:1. Cheap price for very good quality. Customer service and support to help with any and all questions. Super fast shipping. And best of all its super bright. Even in day light.

Disadvantages: Some vibrating noises, but may just be my tag.

Honestly makes the bike look so much cleaner than the stock junk they have. Took me roughly a half hour to install. As for the cutting I wouldn’t worry about it. It’s not a huge cut you have to make its pretty easy. I love it.

Advantages: Everything

Disadvantages: None honestly
