Well, not today! Not happening here with KX100!

This one comes with a 99cc two-stroke liquid mini engine. It helps the riders to gain that performance gap from the minis to the full-size bikes. This means the young and adults everyone around 5’3”-5’4” can ride this.

Kawasaki KX100 Top Speed

Well, there’re some comments about KX100 that ‘if you want to go faster in the air, take an airplane, but if you want to win the roads, go for KX100’.

Why do you think this statement came for? Of course, the speed limit of this beast is remarkable, that’s why.

KX100 top speed is 60-70 mph; that’s basically a decent limit for this two-wheeler. Obviously, the limit will vary from different factors like wind, surface, road condition, altitude, and maintenance. Sometimes, the rider’s weight plays a huge role in the speed component.

Hence, some users talked about how they had an experience of 75-80 mph, which explains how it differs from user to user.

The most exciting part about the top speed of KX100 is that it comes with 6-speed gears. You may already know how important it’s to have multiple gears to enhance the pace of your favorite motorbike.

As it has extra 5th and 6th gear, they’re considered the overdrive ones that permit excessive speed while keeping low engine revolutions. A win-win.

How to Increase Kawasaki KX100 Top Speed?

In this part, we’ll be sharing some tips on how to increase the speed limit of KX100 without flowing cash in the mechanic shops. Still, these hacks are for those experienced in this field or at least know the basics of motorbikes. So, if you think you can do this by yourself, go ahead!

Therefore, applying these tricks will surely help your bike to gain 4-5 mph more if the task is done properly. Let’s see!

1. Replace the Gear ratio

Replacing the gear ratio of your bike will change the revolutions of a driveshaft per revolution of your bike’s wheel. It’ll do wonders, especially if you purchase a TLD for the predator.

Also, to make the quad faster, drop 1 tooth from the front 14T and go 3 teeth up from 38T. And yes, if you’re interested in the acceleration vs. top speed, do it in reverse.

All you need to do is go up in the front to 15T. Done!

2. Change the Carburetor

You should definitely change the carburetor part of KX100 to increase the top speed. Look, the carburetor is used to stock more air and fuel for the bike, as we all know.

Upgrading that space will work incredibly; it means you can reserve more fuel and air, and as a result, your vehicle’s horsepower will be upgraded.

And once the horsepower is updated, the top speed limit will be enhanced too!

The bottom line is always to purchase carbs to ensure more fuel delivery, throttle response, and increased power. Plus, never cut the springs of the purchased carbs, as this won’t actually help to expand the speed limit!

There’re also some signs when you definitely need to change the carburetor. Like when,

  • It causes low fuel economy
  • The bike idles too fast
  • It floods when trying to start it
  • The bike stalls at low speeds
  • Hesitates under more load

Observe these issues and change the carb right away!

3. Attach Bog Bore Kits

Actually, a bog bore kit makes a huge difference, you may not feel it before attaching it to your bike, but it does wonder.

The bigger your bore (Oversized cylinder and piston) is, the more your KX100 will be getting power. Not only that, but also it creates big spaces which allow big valve openings that can bring more air and fuel into the cylinder.

A big bore with a short-stroke can also make the engine rev high while creating more horsepower. Thus it’ll expand the speed limit!

4. Examine the Carb Needle

Last but not least, never forget to check the needle of your carb if it’s lifting or not. Try to clean it every day if it’s not elevating. Otherwise, the performance of the quad will be disrupted, and it’ll limit the speed while riding.
