The Polini 910 carena S bike is available in water cooled or air cooled versions, both producing 6.2hp. Obviously the water cooled is going to have the advantage over the air cooled with slightly better performance however even the air cooled moto is a fantastic bike.
This bike also comes in an air cooled 4.2hp model, which again is a great bike, not as good as the GP3 Junior but still worth a go.
