You can increase the top speed of TTR 125 by spending a bit of extra money. But how? This portion will give you the answer. Here we’re going to show some effective tips and tricks to increase the top speed. Let’s see how. 

1. Put your bike on a diet

Are you wondering how weight loss is related to speed increment? Let’s explain.

Actually, weight has a deeper connection with speed or performance than we think. Technically, putting more weight on a bike means a lag in performance. Consequently, it affects the mileage and top speed of your bike. 

When a bike pulls the excess weight, it’ll consume more power than a rider with a lighter weight, even though they’re riding the same bike. The bike with a heavy rider will generate less speed. 

However, that doesn’t mean you have to lose your body weight for more speed. The trick in this fact is removing heavier accessories from your bike.

For instance, you can equip a light exhaust system with your bike. You can remove some other parts like the leg guard, metal grab rails, and center stand. Apparently, it will lessen about 5-6 kg easily. 

2. Give your carburetor a makeover

Carburetor tuning can enhance the speed of your bike dramatically. The best part is that tuning the carburetor is more convenient than throttling the full-body fuel injection systems. When you tune the carburetor, it’ll ensure a perfect mixture that will result in smoother performance. 

In case you’re not satisfied even after tuning the carburetor, you can replace it. Thankfully, some pre-tuned performance carburetors like the FYIYI Carb Carburetor are available in the market. You can replace the old one with this type of tuned carburetor. 

3. Make sure the fueling is right

This trick is connected with the carburetor section. It’s a naked truth that fuel is the main energy source in dirt bikes. If you can ensure the correct fueling in your dirt bike. 

Again, you can go for a good carburetor or choose one of the cheap knockoffs. This will ascertain the right fuel supply. By fueling your bike, you can maximize the performance, in other words, the top speed.  

4. Change the tires

If your bike’s tires don’t have proper tread, it is possible to slip while accelerating. Bikes around 125cc or this TTR 125 are not on the heavier side, so it’s a common factor in the absence of proper tread depth.

As you’re going to accelerate your bike with bald tires, it’s likely to get less grip, reducing top speed.  So, check the tread of both tires and replace them if it’s necessary. 

5. Sprocket Mod

Using the right combination of front and rear sprockets can bring considerable changes in the top speed and acceleration of your TTR 125. To do so, you have to replace the stock sprockets with aftermarket models. 

What’s the right combination? You must purchase a front sprocket with fewer teeth, whereas the rear sprocket should have more teeth than the existing pair. Updating the sprocket means you’re making changes in your bike’s gearing. 

Every gear of a dirt bike is fixed with a powerband controlling. Making changes in the sprocket will affect the power band of a particular gear. However, upgrading the sprockets of your bike won’t increase horsepower.
