Fixing the Mushy Honda Grom Suspension Setup
If you've invested more than five minutes within the saddle, you already understand how the stock honda grom suspension feels a lot like riding a pogo stick made from marshmallows. It's main things owners make a complaint about, and for valid reason. Honda built this bike in order to be affordable, fun, and accessible, which usually means they had to cut sides somewhere. Unfortunately, that will "somewhere" was the particular damping and spring rates.
Whether you're using your Grom for a daily commute, striking the local go-kart monitor, or just understanding how to wheelie in a parking lot, the manufacturing plant suspension is most likely holding you back. It's far too soft for the typical adult rider, resulting in a front finish that dives like a submarine each time you contact the brakes and also a rear end that will bounces uncontrollably more than the slightest lump. Let's break up exactly why it's such as this plus what you may actually do in order to fix it without having draining your whole bank account.
Exactly why the Stock Setup Fails Most Motorcyclists
The biggest issue with the particular factory setup is the fact that it's designed with regard to a very specific (and light) demographic. In the event that you weigh even more than 130 pounds, you're already pushing the limits of what those internal springs were meant to handle. When you're riding, you would like the bike in order to stay composed. You want it to soak up the impact but then settle back lower immediately.
With all the stock honda grom suspension , that "settling down" component just doesn't happen very well. The top forks have nearly zero rebound damping, meaning once they compress, they spring back up with just about all the grace of a caffeinated squirrel. This makes the particular bike feel nervous in corners. If you hit a mid-corner bump, the particular whole chassis gets upset, and you lose that feeling of planted self-confidence that makes small-bore bicycles so exciting.
The particular rear shock isn't much better. It's a basic device with very little adjustment—usually just pre-load, if you're fortunate. It lacks the internal valving necessary to control the motion of the swingarm. This is the reason, when you hit a velocity bump, the back of the bike often kicks up plus tries to profit you off. It's not just an annoyance; it's a functionality bottleneck.
Starting with front side Forks
A lot of people start their suspension trip at the top because that's where the "brake dive" happens. Whenever you press the front brake pedal lever, the forks compress so quick that the angles of the bike adjustments instantly. This can make the steering experience twitchy and unstable right at any given time to be precise.
The Budget Repair: Fork Oil and Spacers
In case you're on the tight budget, a person can actually make a noticeable difference simply by changing the hand oil. Most Groms come with a very light-weight oil from the manufacturer. Swapping that to a heavier 15w or 20w shell oil can slow down the movement from the forks just enough to make them feel less like toys. Some riders furthermore add small spacers to the top of the springs to increase preload, which helps the bike sit a little higher in the stroke. It's not really a perfect repair, but for the cost of the bottle of oil and an afternoon within the garage, it's an enormous improvement more than stock.
The particular Real Fix: Hand Cartridge Kits
If you're serious about handling, you're going to desire a cartridge kit. Brands like Ohlins, RacingBros, and Koso make drop-in packages that completely change the guts associated with your forks. These kits give you actual valving and, oftentimes, adjustability intended for compression and rebound.
Installing a cartridge package transforms the front side end. Suddenly, the bike stays degree under braking. You can feel what the front tire does. It turns the Grom from the "play bike" directly into a legitimate mini-moto machine. It's arguably the single best modification you can make in order to the bike, much more than an exhaust system or a huge bore kit, since it enables you to in fact use the speed you already have got.
Sorting Out there the Rear Shock
As soon as you fix the front, the back of the bicycle will suddenly experience even worse by comparison. It's a bit of a handling act; if 1 end is firm and controlled and the other will be soft and bouncy, the bike can feel hinged in the particular middle.
Updating the rear honda grom suspension is actually the bit easier than the front because it's usually only one bolt at the particular top and one with the bottom. A person don't have to deal with messy oil or specialized fork tools.
Choosing the Right Shock
There are loads of options here. On the basic side, you possess brands like YSS or DNM. These are miles better than stock and usually offer pre-load and rebound changes. For most street riders, this is all you really need. It stops the "bucking bronco" effect and makes the bike feel significantly more stable at high speeds (or what passes for high speed on a Grom).
When you're racing or just want the best of the best, you look toward Ohlins or Nitron. These shock absorbers often feature remote control reservoirs which help keep the oil cool during intense riding. They also offer a broader range of flexibility, allowing you in order to tune the bicycle specifically for excess fat and riding style. It might seem overkill to place a $600 shock on a $3, 500 bike, however the first time a person lean it directly into a fast sweeper without the back end wobbling, you'll understand why people do it.
The Difference in Real-World Handling
So, exactly what does a better honda grom suspension actually experience like on the road? The first thing you'll notice is the particular "planted" feeling. Rather of feeling such as you're floating on top of the road, a person feel like you're connected to it.
When you approach a corner and downshift, the bike doesn't pogo. If you lean over, the bike keeps its line instead of drifting broad. But honestly, the particular biggest benefit for many people is comfort. It sounds counterintuitive, but a "stiffer" or more handled suspension is usually convenient than the soft one. A soft suspension feet out, sending the particular force of the bump directly in to your spine. The well-tuned setup absorbs the energy and dissipates it with the damping, keeping your vehicle smooth and managed.
For the stunters out right now there, suspension is every thing. Trying to find out circles or even basic wheelies is ten times more difficult when your forks are bouncing each which way. A stiffer front end provides you with a constant platform to put the bike up, and a better rear shock helps you maintain control as soon as you're at the balance point.
Can You Do It Yourself?
Among the best things about functioning on a Grom is that everything is small and relatively easy to access. You don't need a heavy-duty lift or the massive shop. A basic group of sockets, some hex tips, and a way to help the front of the bike (like a front stand or maybe some straps to some garage rafter) is generally enough.
Front side forks are the particular most intimidating part. You'll need to remove the hand legs, which involves removing the front wheel and fender. If you're just changing the oil, it's pretty straightforward. If you're installing cartridges, you might need the special tool to undo the bolt at the underside of the fork leg, but numerous riders find methods to DIY it.
When the concept of opening upward fork legs can make you nervous, any local bike shop can do it for you personally in an hour or two. The rear surprise, however, is the 15-minute job that will almost anyone can do. Just make sure the bike will be properly supported therefore it doesn't collapse when you pull that top bolt out!
Conclusions on the Upgrade
The Grom is a legendary bicycle due to its personality, but its factory "legs" definitely leave something to be desired. Investing in your own honda grom suspension isn't simply about going faster; it's about producing the bike more secure, more predictable, and significantly more fun to ride.
You don't have to buy the nearly all expensive racing components on 1. Start with the basics—maybe some heavier fork oil and the decent budget rear shock—and see exactly how it changes the particular character of your own ride. You'll possibly find that the bicycle feels like it's lastly "grown up, " even when it's nevertheless the smallest thing within the parking lot. Once you feel the difference of a dialed-in suspension, you'll wonder how a person ever managed to ride it stock for so long.
