Upgrading your Honda CRF50 pitbike can transform your riding experience, making it more comfortable, powerful, and fun. Whether you are a beginner or an experienced rider, certain modifications can significantly improve your bike’s performance and handling. This post covers some of the best upgrades you can make, focusing on handlebars, suspension, engine big bore kits, and exhaust systems. These enhancements will help you get the most out of your CRF50 and enjoy every ride.

Upgrading Handlebars for Better Control
The handlebars are your main point of contact with the bike, so upgrading them can improve your control and comfort. Stock handlebars on the CRF50 are often basic and may not suit every rider’s style or size. Here are some benefits of upgrading your handlebars:
Improved ergonomics: Taller or wider handlebars can reduce strain on your wrists and shoulders.
Better control: Stronger materials and reinforced designs help handle rough terrain.
Customization: You can choose handlebars with different bends or grips to match your riding style.
When selecting new handlebars, consider materials like aluminum for a good balance of strength and weight. Also, look for handlebars with crossbars for added durability. Installing new grips with better cushioning can reduce hand fatigue during long rides.
Enhancing Suspension for a Smoother Ride
The suspension system on the CRF50 is designed for light use, so upgrading it can make a big difference, especially if you ride on rough trails or jumps. Upgraded suspension improves handling, stability, and rider comfort.
Front forks: Consider installing aftermarket forks with adjustable preload and damping. This allows you to fine-tune the suspension based on your weight and riding conditions.
Rear shock: Upgrading to a higher-quality rear shock with better spring rates and damping control will absorb bumps more effectively.
Benefits: Enhanced suspension reduces rider fatigue, improves traction, and allows for more aggressive riding.
Suspension upgrades can be a bit technical, so it’s helpful to consult with a mechanic or experienced rider to find the best fit for your needs.

Boosting Power with a Big Bore Kit
One of the most popular upgrades for the Honda CRF50 is installing a big bore kit. This upgrade increases the engine’s displacement, giving you more power and torque. It’s a great way to make your bike faster and more responsive.
What it does: A big bore kit replaces the stock cylinder and piston with larger components, increasing the engine size from 49cc to around 70cc or more.
Performance gains: Riders often see noticeable improvements in acceleration and top speed.
Installation: The kit usually comes with all necessary parts and instructions, but professional installation is recommended for best results.
Keep in mind that with increased power, other components like the clutch and brakes may need upgrades to handle the extra performance safely.
Upgrading the Exhaust for Better Sound and Performance
An upgraded exhaust system complements the big bore kit by improving airflow and reducing weight. This can enhance engine efficiency and give your bike a more aggressive sound.
Types of exhausts: Aftermarket exhausts come in various styles, including full systems and slip-on mufflers.
Benefits: Improved throttle response, slight horsepower gains, and a sportier exhaust note.
Material choices: Look for lightweight materials like aluminum or titanium for better performance and durability.
Installing a high-quality exhaust can also make your bike stand out visually, adding to its overall appeal.
