Maximize the power potential of your GY6 big-bore build with the TFC Special S-1 High Angle Camshaft. Designed specifically for engines running 58.5mm to 63mm cylinder bores, the S-1 delivers 6mm of valve lift — significantly more than a stock cam — keeping the valves open longer and pushing them further to pull in more air and fuel on every stroke. The result is stronger mid-range and top-end power that a big bore cylinder alone can't fully unlock without a matching cam upgrade.
This is the cam to run when you've already installed a big bore kit and want to extract the full power it's capable of. Pairs well with a high-flow head, performance exhaust, and upjetted carburetor.
- Cam Profile: TFC Special S-1 high angle
- Valve Lift: 6mm
- Intake Lobe Diameter: 26.75mm
- Exhaust Lobe Diameter: 26.35mm
- Cam Gear Teeth: 34
- Cam Bearing: 6002C3
- Model Fitment: 58.5mm–63mm cylinder bores
- Made in Taiwan by TFC
Designed for GY6 QMI/QMJ 152/157 (125cc/150cc) 4-stroke engines running big bore cylinders from 58.5mm to 63mm. Not recommended for stock 57mm bore engines — the aggressive lift profile is optimized for larger displacement builds.
Build Tip: The S-1 cam works best paired with a big bore cylinder (61mm–63mm), a high-flow or big valve head, performance exhaust, and an upjetted carburetor. Running a high-lift cam on a stock head with stock jetting will limit gains and may cause a lean condition at high RPM.
