GY6 125 Tilt-Blade Cylinder Kit

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.
