Again, whether you’re looking for any specific Kawasaki KLX 110 mods for adults, or if you’re looking for some mods for kids, we’ll cover them. In the end, no dirt bike is perfect for each individual and his riding style.

Here are the top Kawasaki KLX 110 suspension mods, motor, exhaust, tires, and more. Overall, these are the best-of-the-best performance mods for a Kawasaki 110cc dirt bike, but they are definitely not all necessary.

Best KLX 110 Big Bore Kits

Upgrading your engine where you’ll really notice significant power and performance gains when modding your KLX 110. One of the most popular and widely-used methods to making a KLX110 go faster and have more power is to install a big bore kit.

If more power is what you’re after, a big bore kit should be on your list. Naturally, adding a big bore kit to your KLX110 will up the displacement, and with that comes more compression, more power, and a better mid-to-top end. Having said that, this KLX 110 mod does have a few drawbacks as well as advantages.

Advantages of a Big Bore Kit

Overall, adding a KLX110 big bore kit will be quite beneficial. Below are some of the top advantages to boring out your 110cc Kawasaki dirt bike.

  • Increased power and torque – Big bore kits can significantly increase a dirt bike’s engine displacement, helping it to produce more power and more torque. Not only does this make the dirt bike accelerate faster, but it also adds to its top speed.
  • Improved throttle response – With the larger engine displacement, the dirt bike breathes better and responds quicker to throttling up or down. Obviously, this makes the dirt bike more responsive and easier to handle.
  • Better low-end power – A big bore kit can increase the low-end power of the engine, which can be especially beneficial for off-road riding where low-end torque is crucial for climbing hills and navigating tricky terrain.

Disadvantages of a Big Bore Kit

  • Hard on the engine – Adding a big bore kit can put more strain on the engine, but it doesn’t have to. If you don’t get a high-quality kit, the increased power and heat from installing the kit can cause more wear and tear on the motor.
  • More frequent maintenance – With the increased power and heat, it’s important to keep up with your regular maintenance. In some cases, you’ll need to perform more frequent oil changes, valve adjustments, and other miscellaneous maintenance items.
  • Decreased fuel economy – Although not the end of the world, adding a big bore kit can decrease the dirt bike’s fuel efficiency.
  • Expensive – Of course, big bore kits can be expensive, but that’s not necessarily the “big spend” that you can expect. Unless you’re able to install it yourself, you’ll have to take into account the price of the kit as well as the price to pay a dirt bike mechanic to do the job.

Don’t let the negatives scare you off. If you’re in the market and considering a big bore kit, there are a few decent options out there. The following are the most popular and are considered the best KLX 110 big bore kits that I was able to find.

KLX 130 Big Bore Kit (Athena 130)

If you’re looking for an easy-to-install, cheap big bore kit for KLX 110 dirt bikes, Athena makes a solid option for bumping up your engine displacement to 130cc.

While this isn’t the only KLX 130 big bore kit on the market, it is one of my preferred choices simply because it does not require any machine work… it’s easy bolt-on power.

Here’s everything that is included in this Kawasaki 130 big bore kit by Athena:

  • Bolt-on performance
  • Big bore cylinder
  • Big bore piston
  • Piston pin and rings
  • Gasket kit

Note: In order to get the most out of this Athena KLX 110 big bore kit, you’ll want to re-jet the carburetor. The jet kits are not included, however, you can pick them up online for cheap.

KLX 143 Big Bore Kit (BBR 143)

Here is another bolt-on big bore kit for the KLX 110. Unlike the BBR 130 kit, the BBR 143 kit does not require you to bore out your engine.

If you’re going to spend the money and do the work, it makes sense to go with this KLX 110 big bore kit since you get a few more CC’s out of the job, and they’re high-quality parts.

Here’s what you get with this kit:

  • Bolt-on performance
  • Aluminum cylinder with plated aluminum sleeve
  • High-Performance camshaft
  • 60mm lightweight aluminum piston
  • Includes gaskets

Note: Just like the 130 kit above, if you’re looking to get the most out of this KLX 110 BBR big bore kit, you’ll want to re-jet the carburetor. The jets are not included, however, they are cheap to buy.

High-Compression Wiseco Piston

Got torque? If you’re looking for more torque, consider an aftermarket KLX 110 piston for part of your build.

Even though you’re not going to milk out a ton more horsepower, these high-compression pistons do provide a solid improvement to your low and mid-range power. If you’re up to it and you’ve got the room in your budget, adding a better piston is a solid KLX 110 mod to improve its performance.

KLX 110 Exhaust Mods

One of the first upgrades that many of us make to our dirt bikes is adding an aftermarket exhaust. There are quite a few companies that make KLX110 exhausts, but I can’t say that I’d recommend buying from all of them.

Adding a new exhaust system to your dirt bike should improve throttle response, increase horsepower, and make your bike sound better. However, if you go out and buy the cheapest aftermarket exhaust you find… you’re going to get what you pay for. (Yes – sometimes “cheap” is the more appropriate option)

Best Aftermarket Exhaust

When it comes to exhaust systems, the Yoshimura KLX110 exhaust is one of the best options out there. This aftermarket exhaust for KLX110 dirt bikes sounds incredible, yet isn’t too loud.

Here are just a few of the positive reviews and features of these exhaust systems:

  • Improved throttle response
  • Good low-end snap
  • Works with a big-bore kit
  • Top-quality build
  • Looks finished and “professional”
  • Lightweight
  • Easy to install
  • Not too loud

Stock Exhaust Mod

This may or may not be good news, but you can upgrade your stock exhaust with a little work. If you’re willing to do some cutting and welding, you can simply gut your stock KLX110 exhaust and make it perform (and sound) much better.

Here’s a great video showing exactly how some guy did this.

Arrow pointing to video

NOTE: I haven’t run a KLX110 with a gutted exhaust before, but I do hear they sound and work great. A while back, I bought a Husqvarna SMR510 that had the dual stock exhaust gutted. It worked and sounded really good.

KLX 110 Air Filter & Airbox Mods

If improved airflow and increased power is on your list, an aftermarket KLX110 air filter should be on your list. Adding a new dirtbike air filter is a cheap and easy upgrade that’s definitely worth doing.

BBR U-Flow Kit

While adding an air filter is good, you may want to look into adding the BBR U-Flow as well.

Close up of the BBR U-Flow Air Filter Kit on white background

The BBR U-Flow Air Filter System is very smart. In order to keep dirt and mud out of the airbox, the U-Flow makes it so that the air filter is reversed. Not only does this help to prevent debris from getting into the motor, but this unique design also delivers more air and makes for better throttle response.

NOTE: If you do end up buying the U-Flow kit just remember that you will need to re-jet your bike. BBR includes a list of recommended sizes that are quite accurate. Of course, you’ll need to verify.

KLX 110 Suspension Mods

Upgrading your suspension is one of the best mods that you can do to your Kawasaki KLX110. Not only can stiffer springs and shocks make these dirt bikes better for jumping, but they usually handle better all the way around.

If you’re looking to stop bottoming out and over-stressing you’re dirt bike’s suspension and chassis, upgrading the suspension is one of the most important mods you can make. Not only will this make your dirt bike handle better, but it will also allow you to go faster because you can stay in control and position for proper riding technique.

Front Fork Upgrade

Since the stock Kawasaki KLX110 forks are made for an 80-100 pound rider, they’re going to be too soft for just about any adult riding one as a pit bike. Therefore, if you weigh 115+ pounds, upgrading the front forks will give you better control and will prevent your dirt bike from bottoming out as often.

Granted, adding new forks to your dirt bike may sound a little intimidating, however, it isn’t too difficult of a job. In fact, doing some KLX110 suspension upgrades should drastically improve the overall ride of your bike.

If you do decide to mod your KLX110 front forks, the KX65 fork swap is a very popular option, however, it isn’t the easiest to do. An easier project would be to buy some aftermarket forks (like the ones from JCMOTO) and new triple clamps.

Whichever you choose, there’s no doubt that you’ll enjoy the added performance from upgraded front forks.

Swingarm Conversion Kit

If you’re looking for the ultimate setup, it’s going to be hard to beat the KLX 110 BBR Swingarm kit.

Close up of the BBR Swingarm Mod for KLX 110

Not only do these perform better than the stock Kawasaki swingarm, but they also install easily and look great. While they certainly are not one of the cheap KLX 110 mods, adding one of these swingarms will certainly improve the ride and performance of these little pit bikes.

Here are some of the main features that they brag about, not that you can blame them:

  • Forged 6061 aluminum side spars
  • TIG welded and heat treated to T6
  • Bead blasted and Bright Dip anodized finish
  • Ride height adjustable between standard and +1″
  • Chain guide on all models
  • Adds 1.75″ over stock length
  • Includes brake rod extender

ELKA Rear Shock

Okay, let’s say that you have (or are going to) spend the big bucks on an aftermarket swingarm. What next? Now it’s time to upgrade the shock.

ELKA shock for KLX 110 mods

If you want a truly updated rear suspension, an ELKA shock is probably going to be at the top of your list. This aftermarket KLX 110 rear shock is one of the best options on the market. No more bottoming out on every little jump and bump.

With this shock mod, you should find that your bike handles much better and is more pleasant to ride. Here are the main features of this ELKA rear shock:

  • Adjustable spring preload
  • Adjustable rebound damping
  • Light weight hard anodized aluminum body
  • Large 16mm shock shaft
  • Low friction internals
  • Triple sealing seal head design

KLX 110 Tires

Putting some new tires on your KLX110 may not sound like a “mod” but you’ve got to consider this. And what’s even more…. a new front tire makes just as much (in some situations – more) of a difference than a new rear tire.

Either way, putting a set of new tires on your dirt bike is actually a very wise decision… even if they’re a stock replacement. Either way, the following is what I’ve found to be some of the best dirt bike tires that you can get for a KLX110.

Best Tires for Trail

Although I don’t (currently) have a Kawasaki KLX110, I do run Starcross 5 dirtbike tires on my CRF450. They are really nice tires and they hook up great. Are they perfect? Of course not.

Since you’ve got to choose what type of riding you want to do, you’ve got to choose which tire will be best suited for that type of riding. With that said, I feel that a medium terrain tire is ideal for “all” types of riding, although you can choose a tire for hard, soft, or intermediate terrain. Generally, intermediate fits the bill adequately most of the time.

KLX 110 Dirt Bike Armor

Okay, so you’re ready for some serious off-roading? Putting some dirt bike armor like a skid plate, frame cradle, and even some bark busters isn’t the worst idea. With these inexpensive add-ons, you can make your KLX110 much more durable and trail-ready.

Here are the best KLX 110 mods for making your dirt bike more bulletproof.

Skid Plate

If you’re planning on doing a lot of trail riding where there are large rocks, roots, etc., a skid plate isn’t a bad idea. BBR makes a good skid plate for KLX110 dirt bikes. They aren’t the cheapest, but these skid plates are built well out of anodized 6061 aluminum and they’re quick and easy to install.

Something to think about… these do add extra weight. If you’re sticking to groomed terrain then you may not want to bolt one on.

Frame Cradle

Although they may look similar at first, a frame cradle is quite a bit different than a skid plate and should also be considered for adding to your dirt bike. (yes, you can have both)

Kawasaki KLX 110 Cradle

Installing a KLX110 frame cradle will support your motor and foot pegs. This drastically reduces the braking of motor mounts and footpeg mounts. Even if they don’t brake, the foot pegs are still susceptible to sagging and the cradle adds the needed support to prevent that.

Cheap KLX 110 Mods

Not every Kawasaki KLX 110 mod needs to be expensive to be warranted. Yes, it’s true that most suspension and engine mods are not cheap, the following upgrades shouldn’t break the bank.

While you may not be improving your track time with every dirt bike modification, there’s a lot to be said for comfort… as well as just for looks.

Wider Footpegs

Buying aftermarket KLX110 foot pegs may not be the first thing that comes to mind for modding your Kawasaki 110cc dirt bike, but these are a welcome upgrade for most.

Arrows pointing at two aftermarket Kawasaki KLX110 Foot Pegs

The stock Kawasaki foot pegs aren’t the best. They’re fairly narrow and don’t have the best grip. There are a few different companies out there producing good foot pegs for KLX110 dirt bikes. Basically, whichever ones you go with you should be able to tell a noticeable difference.

Here’s a link to view pricing and read reviews of these IMS Super Stock foot pegs on Amazon, and here’s a link to view pricing and read reviews of the Dr. Dry foot pegs on Amazon.

Taller Handlebars

Upgraded handlebars are one of the first KLX 110 mods that we adult riders do. The stock bars are not only a bit short, but they’re also fairly weak and just not “cool.”

Unfortunately, if you install the full kit with triple clamps, you will need a longer brake and throttle cable. Not a big deal, but something to be aware of.

If you’re interested in keeping your stock triple clamps and cables, but you’d still like a set of aftermarket KLX110 handlebars, check out these Pro Taper 7/8 handlebars on Amazon.

If you’re planning on replacing the triple clamps and don’t mind adding the longer cables, check out this Pro Taper kit for the KLX110 on Amazon. This is a nice kit because it includes the handlebars, the triple clamps, and the dirtbike handlebar grips all in this one kit.

Aftermarket Plastics

Okay… buying plastics and graphics is certainly not necessary, but it’s something we all end up doing. Whether you buy a new set of replacement Kawasaki KLX110 plastics for when you ruin yours, or if you buy new plastics purely for an updated and unique look, these are a cheap and easy way to make your dirt bike look newer.

One thing that I (almost) always do is buy different colored plastics for different sections of my bike. Sounds weird but it’s an easy way to make you’re KLX110 look unique. For example, I had a 2001 YZ426F that I put gray plastics on the back and blue on the front. It looked great! I wish I had a picture of it still.

Here’s a similar look (different colors, of course) that I put on my Husky SMR510.

See… black plastics in the back with white plastics up front… looks pretty good (to me).

Anyway, here are some decent plastics you can pick up for cheap from Amazon. There are white plastics, gray plastics, and green plastics to choose from.

Again, I recommend mixing it up a bit but the choice is yours.

Once you’ve figured out your plastics, then you should look into buying graphics. Also, you can (probably should) shop for plastics and graphics at the same time. Look for a graphics kit that you like and then find a combo of plastics that will complement the graphics.
