• 34 teeth ensure precise timing and optimal power transfer through the drivetrain.
• 25.7mm intake lobe width is optimized to draw in a potent air-fuel mixture for increased combustion efficiency.
• 25.5mm exhaust lobe width facilitates rapid expulsion of exhaust gases, promoting cooler engine operation and higher RPM potential.
• Engineered to utilize **16002/P6 bearings** for smooth operation and extended durability.
• Includes the **integrated sprocket** for a complete and convenient camshaft replacement solution.

Compared to stock camshafts found in standard GY6 50cc engines, this performance-tuned upgrade offers a noticeable boost in acceleration and top-end speed. It's specifically designed to complement the airflow and combustion characteristics of modified 4-stroke QMB139 platforms, providing a more aggressive power curve without sacrificing reliability.

Key Technical Advantages: Advanced Technology and Enhanced Performance

This camshaft leverages precision engineering to maximize the breathing capabilities of your GY6 50CC engine. The carefully sculpted lobe profiles increase valve lift and duration, allowing more air and fuel into the cylinder and more exhaust gases out, directly translating to greater horsepower and torque. Its robust construction ensures it can withstand the demands of spirited riding and higher engine speeds, making it an essential part for serious scooter tuners.
