What is the wheel size of Kawasaki Vulcan S?

I am bit dissapointed for the ground clearnce. Its very low and usually crashes on steep speed breakers and even on road damages. You need to slow down to about 10km/h for many of the speed vreakers. Aditionally as compated to sports bikes this bike is not good in shock absorption. The bike may feel heavy in traffic when bike will be running at nearly 10kmph. But after few months it gets really easy to ride it in traffic.Aditionally as to turning circumference of bike is really high (as always in chopper-cruiser bikes) it may give you difficulties in turning more than 90 degrees in the traffic.I will add one more thing here as the seat height is low, the control and balancing never gives any issue. But at the low speeds, rider's legs can feel heat from the engine.
