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

The Details ⚙️

Want 23–25 horsepower out of a GY6? This is how you do it.

The ProBld 232cc Engine Kit is a full, ground-up build designed to create one of the most powerful GY6 setups possible. This is not a refresh, not an upgrade — this is a complete monster build using top-tier components throughout.

Built around a 67mm big bore and 8.2mm stroker crank, this long-case setup delivers massive torque and power across the entire RPM range. Expect the ability to cruise comfortably at 50 mph with throttle left — and push toward extreme top-end speeds when fully dialed.

This kit replaces everything — no need to reuse parts from an existing engine.

If you want the meanest GY6 engine possible — this is it 🔥
