Finding the right 2018 honda grom accessories is basically the first thing most people do after getting their hands on this legendary little bike. Let's be honest, the Grom is a blast right out of the box, but Honda definitely left some room for improvement—or at least some room for us to make it our own. It's a blank canvas that's just begging for a few tweaks to make it faster, louder, or just plain cooler.
The 2018 model, which falls right in the middle of that second-generation body style, is arguably one of the best versions to mod. Whether you're looking to turn it into a stunt machine or just want a better commuter, there's a massive world of parts out there.
Fixing the "Diving Board"
If you've looked at your bike from the side, you've probably noticed that massive plastic shelf hanging off the back. Most people call it the "diving board," and it's usually the first thing to go. Swapping that out for a fender eliminator is probably the most popular of all 2018 honda grom accessories.
It's a simple change, but it completely transforms the silhouette of the bike. You go from looking like a utility scooter to a tight, aggressive little streetfighter. Most kits are plug-and-play, meaning you won't have to spend hours hacking away at your wiring harness. Just a few bolts, maybe some new LED turn signals, and you're golden.
Giving it some "Braap"
We have to talk about the exhaust. The stock pipe on the 2018 Grom is well, it's quiet. A bit too quiet for a bike that thrives on personality. Upgrading the exhaust is about more than just noise, though. The stock system is surprisingly heavy because of all the baffles and emissions gear inside.
When you start looking at exhaust systems, you'll see brands like Yoshimura, Akrapovic, and Zoom. A high-mount exhaust keeps that classic look, but a low-mount can really change the vibe. Not only do you get a much deeper, throatier sound, but you also drop a few pounds of dead weight and gain a tiny bit of throttle response. It won't turn your 125cc into a liter bike, but it definitely makes it feel a lot peppier.
Better Bars and Controls
The stock handlebars on the 2018 Grom are okay, but they feel a little "standard." If you want a more aggressive stance or just better ergonomics, a set of ProTaper or Renthal bars is a game changer. Most riders go for the "Honda Mini" bend, which lowers the profile slightly and gives you a much sturdier feel.
While you're at it, you'll probably want to swap out the grips. The stock ones are pretty hard and can get uncomfortable on longer rides. Throwing on some pillow-top grips or something with a bit more cushion makes a huge difference. Also, let's talk about the mirrors. The stock "Mickey Mouse" mirrors are notorious for showing you more of your own elbows than the traffic behind you. A set of sleek bar-end mirrors solves that problem and makes the bike look ten times wider and meaner.
Performance and Intake
Once you've got the look and the sound down, you might start itching for a little more speed. Since the Grom only has so much power to give, every little bit counts. A cold air intake or a "modded airbox" is a common step. By letting the engine breathe better, you're helping that new exhaust do its job.
However, if you change the intake and the exhaust, the bike might run a bit lean. That's where an EFIE or an ECU flasher comes in. It's one of those 2018 honda grom accessories that you don't "see," but you definitely feel. It smoothens out the power delivery and makes sure your engine stays healthy with the new airflow.
Comfort for the Long Haul
Let's be real for a second: the stock seat on the 2018 Grom isn't exactly a sofa. After about 45 minutes of riding, you start to feel every bit of that 125cc vibration. Upgrading to an aftermarket seat like a Corbin or a Bride-style seat is a lifesaver if you plan on doing anything more than a quick trip to the grocery store. These seats often have better foam and a flatter profile, so you aren't constantly sliding forward into the gas tank.
Protecting Your Investment
Since the Grom is such a light, flickable bike, it's prone to "little accidents"—especially if you're learning how to wheelie. Frame sliders and crash bars are essential 2018 honda grom accessories for anyone who plays a bit hard. A good set of sliders can be the difference between a scratched-up plastic fairing and a cracked engine case. Plus, they give the bike a more rugged, industrial look that fits the Grom's personality perfectly.
For those who are really into the stunt scene, a subcage is a must. It reinforces the rear of the bike and gives you a solid place to put your feet or scrape on the pavement (if that's your thing). Even if you aren't a stunter, a beefy skid plate is a great idea if you like hopping curbs or taking your Grom on light trails.
Lighting Up the Night
The 2018 Grom already came with an LED headlight, which was a nice upgrade from the older models, but there's always room for more light. Many riders add integrated tail lights that combine the brake light and turn signals into one unit. It's super clean and eliminates the need for those "stalk" blinkers that always seem to get bumped or broken.
If you do a lot of night riding, adding some small LED pods or even underglow (if you're feeling nostalgic for the 2000s) can help people see you. On a bike this small, being visible is half the battle when you're sharing the road with SUVs.
Making it Yours with Aesthetics
Finally, there's the purely visual stuff. Graphic kits are huge in the Grom community. You can find everything from race-inspired liveries to completely wild, custom designs. It's the easiest way to make sure your 2018 Grom doesn't look like every other one at the local meet.
You can also look into anodized parts—things like engine bolts, oil dipsticks, and chain adjusters. They come in every color imaginable. If you have a red Grom, adding some red CNC-machined bits really ties the whole look together. It's all about the details.
Wrapping it Up
The beauty of looking for 2018 honda grom accessories is that there's no right or wrong way to do it. Some people want a touring bike with racks and bags, while others want a stripped-down street machine. Because the parts are generally more affordable than they are for "full-sized" bikes, you can afford to experiment.
Start with the basics—the fender and the exhaust—and see where it takes you. Half the fun of owning a Grom is the constant tinkering. You'll find that as soon as you finish one mod, you're already looking at the next one. That's just the Grom life. It's a small bike with a massive aftermarket, and it's all about having a good time on two wheels.
