GY6 232cc 2V Water Cooled Complete Engine Kit - PROBLD

The Details ⚙️

Want 23–25HP out of a GY6 — and keep it cool doing it? This ProBld 232cc Liquid & Oil-Cooled Engine Kit makes it possible.

This is a 232cc long-case stroker build featuring a 67mm big bore, 8.2mm crank, and a full cooling system designed to handle serious power. Compared to air-cooled setups, this configuration allows for more consistent performance, better heat control, and higher sustained speeds.

Expect the ability to push toward ~95 mph when fully dialed, while still cruising comfortably at 50 mph with throttle left.

This is a complete ground-up build — you will not reuse parts from an existing engine.

If you want maximum performance without heat holding you back — this is it 🔥
