Finding the right 2020 honda grom parts can turn a fun little bike into an absolute beast on the street. Let's be honest, half the reason anyone buys a Grom is because they want to mess with it. Whether you're looking to squeeze out a tiny bit more top-end speed or you just want to make sure it doesn't look like every other bike in the parking lot, the aftermarket scene for the 2020 model is massive. It's one of those rare bikes where you can actually spend more on mods than you did on the bike itself if you aren't careful.
The 2020 Grom is a bit of a sweet spot. It sits right at the end of the second generation (the SF model), meaning almost every company on the planet has perfected their parts for it by now. You don't have to worry about "first-year" bugs or parts that don't quite fit. Everything is pretty much bolt-on and go.
Starting with the Basics: The "Tail Tidy"
If you've just picked up a stock bike, the first thing you probably noticed is that massive plastic appendage hanging off the back. Why Honda decided to give the Grom a tail that looks like a diving board, I'll never know. One of the most essential 2020 honda grom parts is a fender eliminator kit.
It's a simple mod, usually taking about 30 minutes with basic tools, but it completely changes the silhouette of the bike. It tucks the license plate up under the rear seat and usually comes with some sleeker LED turn signals. It's cheap, it's easy, and it's basically a rite of passage for every Grom owner. Once that's gone, the bike actually starts to look like the aggressive little streetfighter it was meant to be.
Making Some Noise: Exhaust Systems
Let's face it: the stock exhaust on a 2020 Grom sounds a bit like a sewing machine. It's quiet, it's heavy, and it's tucked away behind a bunch of heat shields. Upgrading the exhaust is usually the second thing people do.
When looking for 2020 honda grom parts in the exhaust category, you've got two main routes. You can go for a low-mount exhaust, which keeps the weight down low and gives it a modern look, or a high-mount that mimics the classic style. Brands like Yoshimura, Akrapovič, and Zoom Exhaust are the big players here.
Besides the sound—which becomes a much deeper, throatier "thump"—you're also dropping about 5 to 10 pounds of dead weight. On a bike that only weighs about 230 pounds, losing 10 pounds is actually a huge deal. You'll feel it in the flick-ability of the bike immediately. Just keep in mind that if you go for a full system, you might want to look into an intake and a fuel controller to keep everything running smoothly.
Better Handling with Suspension Upgrades
One thing most owners agree on is that the stock suspension is well, it's built for a certain price point. It's a bit "pogo-stick" like. If you weigh more than 150 pounds or you like to take corners with any kind of speed, you'll notice the front end dives like crazy under braking.
Swapping out the fork internals or getting a new rear shock are some of the best 2020 honda grom parts you can invest in for actual ride quality. An Ohlins rear shock is the gold standard, but even a YSS or Koso shock will make a world of difference. It stops the bike from bouncing over every little pebble and makes the whole ride feel way more planted. If you're planning on doing any "stunt" riding (we won't tell), a beefier suspension is practically mandatory.
Ergonomics and Comfort
The Grom is small—obviously. But it shouldn't feel cramped. If you're taller than 5'8", you've probably felt your knees hitting the handlebars once or twice. This is where bars and pegs come in.
Handlebars and Grips
A lot of people swap the stock chrome bars for something like ProTaper Seven Eighths or Carmichael bends. These lower the profile of the bike and give you a more aggressive riding position. Plus, they look a million times better. While you're at it, some decent grips can save your hands from the vibration of that single-cylinder engine on longer rides.
The Seat Situation
Honda's stock seat on the 2020 model is notorious for being about as soft as a wooden plank. After 45 minutes of riding, you'll start to feel it. Looking into 2020 honda grom parts specifically for comfort often leads people to Corbin seats or those "flat" seats from Thailand. They give you a bit more room to slide back and provide much better cushioning for your backside.
Boosting Performance: Intakes and Sprockets
If you're looking for more "get up and go," you have to realize a Grom is never going to be a liter bike. However, you can make it feel much peppier.
An aftermarket intake (like the Chimera) lets the engine breathe better. When you pair that with an exhaust and a simple ECU flash or a fuel tuner, the bike really wakes up. It won't suddenly do 100 mph, but it'll get to 55 mph a lot faster, and it won't struggle as much against a headwind.
Another "secret" mod involves the sprockets. Swapping the front sprocket to a 14-tooth (one tooth down from stock) is one of the cheapest 2020 honda grom parts swaps you can do. It gives you way better acceleration off the line. You'll lose a tiny bit of top-end speed, but let's be real—the Grom is about the journey, not the land speed record.
Aesthetics and Small Details
Sometimes it's the little things that matter most. Bar-end mirrors are a popular choice because the stock "Mickey Mouse" mirrors are wide and vibrate so much you can't see what's behind you anyway. Bar-ends clean up the lines of the bike and actually stay still at higher RPMs.
Then there are the levers. Stock levers are often non-adjustable and feel a bit flimsy. A pair of shorty adjustable levers allows you to customize the "reach" to your fingers, making clutch work and braking much more precise. You can find these in almost any color to match your bike's paint job.
Where to Buy and What to Look For
When you're hunting for 2020 honda grom parts, it's easy to get overwhelmed by the sheer volume of stuff on the internet. You'll see things ranging from five-dollar bolts on eBay to five-hundred-dollar carbon fiber fairings.
My advice? Don't go for the cheapest thing possible when it comes to mechanical parts. If it's a cosmetic cover or a sticker, sure, go cheap. But if it's a brake line, a chain, or an engine component, stick with brands that have a reputation in the Grom community. There are tons of forums and YouTube channels dedicated specifically to the 2020 model year, so do a little digging before you pull the trigger.
Final Thoughts on Customizing
The beauty of the 2020 Honda Grom is its simplicity. It's basically a LEGO set for adults. You can spend a Saturday morning in the garage with a couple of wrenches and a cold drink, and by the afternoon, you have a bike that feels and looks completely different.
Whether you're building a show bike, a stunt machine, or just a fun commuter, the right 2020 honda grom parts are out there to make it happen. Just remember to take it one step at a time. It's easy to get carried away and end up with a pile of parts in the garage and no time to ride. Start with the stuff that bothers you most—usually that tail or the quiet exhaust—and go from there. The Grom community is huge, and half the fun is seeing what everyone else has done with theirs. So, get out there, start wrenching, and make that bike yours.
