Polini Sport 68cc Big Bore Kit For Honda Dio / Elite AF16 Motor

Your stock Dio was never meant to stay stock.

The Polini Sport Big Bore Kit swaps your Honda Dio, Elite, or AF16 motor up to 68cc — and the result is a throttle response that actually wakes you up in the morning. This isn't a mild tune; it's a proper Italian-engineered upgrade that adds real torque right where you feel it most: low-end pull off the line and mid-range grunt that keeps building.

Polini built this kit for everyday use, which means it's not just fast — it's durable. You can ride it regularly without babying it, which is exactly what a daily commuter or weekend blaster needs.

A few things to know before you bolt it on: to get the most out of this kit, you'll want lightweight vario rollers, a fresh spark plug, and an open exhaust and intake manifold. Bump your main jet up 8–12%, consider a 17.5mm carb, and a racing exhaust will really let it breathe. Set it up right, and this kit transforms your scooter from dependable to genuinely fun.
