Durable Alloy Body with Tilt-Blade Fins for Directed Airflow

The GY6 125 Tilt-Blade Cylinder Kit uses a high-strength aluminum-alloy cylinder with angled cooling fins designed to pair with stock shrouds, helping guide airflow across the cylinder. Offered in 58.5 / 61 / 63mm bore sizes, it suits both standard rebuilds and displacement upgrades while keeping installation straightforward and sealing consistent.

🔹 Aluminum-Alloy Cylinder Body – Rigid structure with good heat conduction
🔹 Tilt-Blade Fin Layout – Angled fins align with OEM shrouds for directed cooling airflow
🔹 Precision Machining – Consistent ring sealing and smooth piston travel
🔹 OEM-Fit Interfaces – Stock-layout mounting for accurate, hassle-free assembly
🔹 Multiple Bore Options – 58.5 / 61 / 63mm to match your build goals
