Factory Performance Without the Factory Price Tag: Build a Factory-Competitive Kawasaki KX112

The Kawasaki KX112 has generated significant buzz in the motocross community since its release. Positioned as a bridge between mini bikes and full-size motocross machines, it promises to provide the performance and handling young riders require to elevate their skills. But does it truly live up to the hype? Let's delve into it and find out.

What makes the KX112 Special?

When it comes to SuperMini motorcycles, only two brands offer a powerful 112cc machine straight out of the box: TM Racing and Kawasaki. The KX112 distinguishes itself from the competition with an impressive array of standard features and exceptional performance. Here are a few key aspects that make the KX112 stand out:

Potent 112cc Engine

The KX112's 112cc two-stroke engine is a powerhouse, renowned for its robust performance across the powerband. Its finely tuned power delivery provides strong acceleration and excellent throttle response, making it ideal for intermediate to advanced riders seeking race-ready performance. Additionally, its lightweight design enhances agility and maneuverability on the track, ensuring riders can confidently navigate corners and tackle challenging terrain with precision.

Standard Big Wheel Configuration

Unlike many SuperMini bikes that feature smaller wheels, the KX112 comes standard with a big wheel configuration. This includes a 19-inch front wheel and a 16-inch rear wheel, resulting in a taller seat height. This setup accommodates taller riders comfortably and gives the bike a feel similar to a full-size motocross machine.

Want to Keep Up with the KTM, Husqvarna, and Gas Gas Bikes Without Breaking the Bank?

The world of SuperMini motocross is fiercely competitive, with brands such as KTM, Husqvarna, and Gas Gas offering high-performance machines that often come with a hefty price tag. However, if you're looking to stay competitive without breaking the bank, consider the Kawasaki KX112. Instead of investing in expensive big bore kits that can exceed $1000, start with a bike that's already equipped with a powerful 112cc engine – the Kawasaki KX112.

Let's talk about upgrading the KX112:

While the KX112 is an excellent bike in its stock form, there are several key upgrades we can make to enhance its performance. Here are a few modifications to consider:

Increase Horsepower: The KX112 falls slightly behind the KTM group bikes by about 1.5 horsepower.

Improve Ergonomics: Address the cramped top triple clamp area by adjusting the rider's triangle. Upgrade to larger foot pegs, adjust handlebars to reduce sweep, and install a gripper seat to enhance stability.

Enhance Clutch Performance: Strengthen the clutch to handle the additional power effectively.

Adjust Gearing: Consider increasing the gearing by going up 1 tooth for small, tight tracks. The stock configuration is 14T front and 51T rear.

These upgrades can significantly elevate the KX112's performance and suitability for competitive motocross.

    What about the soft stock suspension?:  When it comes to suspension, we highly recommend entrusting this crucial component to a reputable company like Pro Circuit or Factory Connection. At our motocross blog, we always strive to focus on bolt-on parts to keep projects DIY-friendly. However, suspension is one area where seeking professional expertise truly make the difference.

          Through the blog, we've suggested many parts for your Kawasaki KX112. Keep in mind that with younger riders, you can build the bike slowly as their skills improve. So, you don't need to purchase everything at once. Sometimes the fun is to add a part, then ride, and then keep adding more performance parts so you can see the improvement as the rider gets better.

          Also, remember that the parts listed are what we found worked best, but nothing is written in stone. You may prefer different brands, and that's all good since racing is all about trying different parts to find what works best for you.
