Why I Believe a CRF50 Big Bore Kit is Necessary

As a long-time rider and owner of a Honda CRF50, I have come to realize the importance of upgrading to a big bore kit. At first, I was hesitant to make the change, thinking it would be an unnecessary expense. However, after doing my research and experiencing the benefits firsthand, I can confidently say that a big bore kit is a necessary upgrade for any serious rider.

The most obvious reason for upgrading to a big bore kit is the increase in power and performance. The stock 50cc engine on the CRF50 is great for beginners or casual riding, but for those looking for more speed and power, it falls short. With a big bore kit, you can increase your engine’s displacement up to 88cc or even 117cc, resulting in a significant boost in horsepower and torque. This means faster acceleration and higher top speeds, making your bike more fun and exciting to ride.

Another reason why I believe a big bore kit is necessary is its ability to handle more aggressive riding styles. As someone who loves to push my bike to its limits on dirt tracks and trails, I quickly realized that the stock engine couldn’t handle the demands of my

My Buying Guide on ‘Crf50 Big Bore Kit’

As a proud owner of a CRF50, I know how important it is to constantly improve and upgrade your bike to enhance its performance. One of the best upgrades you can make for your CRF50 is installing a big bore kit. A big bore kit increases the displacement of your engine, resulting in more power and torque. In this buying guide, I will share my personal experience and knowledge on purchasing the perfect CRF50 big bore kit.

What is a Big Bore Kit?

A big bore kit increases the size of your engine’s cylinder and piston, allowing more fuel and air inside, resulting in increased power and performance. Typically, a stock CRF50 has a 49cc engine, but with a big bore kit, you can increase it up to 88cc. This upgrade is popular among riders who want more power for off-road riding or racing.

Things to Consider

Before purchasing a big bore kit for your CRF50, there are a few things you should consider:

• Budget: Big bore kits can range from $100 to $500 depending on the brand and size. Make sure you have a budget in mind before starting your search.
• Brand: It is essential to choose a reputable brand when it comes to big bore kits as they are responsible for increasing the power and performance of your engine.
• Compatibility: Not all big bore kits are compatible with every CRF50 model. Make sure to check if the kit fits your bike’s year and model before making a purchase.
• Tuning Requirements: Installing a big bore kit may require additional tuning or modifications such as changing the carburetor or exhaust system. Make sure you are prepared for these additional costs.

Selecting the Right Size

The most common sizes for CRF50 big bore kits are 70cc, 88cc, and 108cc. The size you choose depends on your riding style and needs. If you are looking for more power for off-road riding or racing, an 88cc or 108cc may be suitable. However, if you want moderate power improvements for casual riding, then a 70cc may be enough.

• TB Parts Big Bore Kit (88cc): This is one of the most popular choices among CRF50 owners due to its quality build and significant power gains.

In Conclusion

A big bore kit is an excellent upgrade for your CRF50 that can significantly improve its performance without breaking the bank. Before making any purchases, consider all factors mentioned above carefully.
