Why 2 valve?

I am still hoping for a bigger cc from Yamaha. At least 150cc with 4 valve DOHC.

But the EGO 125 is using a 2 valve engine. I hope it will produce enough power to accelerate nicely after the traffic light. I hope it will also have enough power to run nonstop for 2-3 hours for long haulage.

With the EGO and two other equivalent model....... the Modenas and the Suzuki .......the competition is getting tougher...
