What Factors Affect the Top Speed of Suzuki DRZ400?

In order to reach the top speed of the Suzuki DRZ 400, you have to do a lot of modifications which are given below.

  • Installing Pamper-type carb
  • 3X3 modification
  • Big Bore Kits
  • Lightweight Aftermarket Exhaust

Installing Pamper-type Carb and Rejetting

The first thing you can do is replace the stock carburetor with the after-market pamper-type carb. This will improve your bike’s performance, but you can do rejetting first and then replace the carburetor for even more improvement.  

3X3 modification

The 3×3 modification increases the size of the air box by 3×3 square inches. In this way, air will be able to flow more freely into the carburetor, allowing the engine to breathe more easily. This one-of-a-kind modification will increase your bike’s throttle response, leading to better performance.

Big Bore Kits

You can install big Bore kits for better performance. You can also use other Bores along with the big one to increase the overall displacement even further. There are no complicated steps involved in the installation of this kit. Furthermore, you can pair it with the set of camshafts, resulting in a 50-hp boost.

Lightweight Aftermarket Exhaust

You can use aftermarket exhaust which has a chance of getting some increased performance. The stock exhaust is heavier than the aftermarket one and does not even have an edgy sound (Preferred by most people). Therefore, replacing the stock one with the aftermarket will reduce the bike’s weight, which may increase its speed. Although if you don’t want your bike to be noisy, you can go with the stock exhaust.
