SmartCarb 28mm Unibody (LH choke)

SC3 Smart Carb – Performance Meets Precision

Upgrade your ride with the SC3 Smart Carb, engineered to boost horsepower, improve fuel efficiency, and reduce emissions—all in one sleek, high-performance package.

Featuring a unibody design for maximum durability and consistent fuel delivery, the SC3 is compatible with most 150cc–250cc dirt and street bikes. It’s the perfect replacement for the low-quality or poorly tuned stock carbs that come on many imported Chinese bikes.

Breathe new life into your engine with the best carb upgrade available—easy to install, incredibly responsive, and built for serious performance.

The SC3 is similar in dimensions to the PE28 and PWK28 carbs. 

✅ Fits popular models like:

• Orion

• Hawk 

• Apollo 

• Trailmaster

• Mototech

• Kao

Note: While the SC3 28mm is designed to work with most 150cc–250cc engines, direct bolt-on fitment is not guaranteed for every bike. Some models may require minor adjustments during installation.

Get ready for better throttle response, easier starts, and a smoother ride every time.
