sit on one and see if your feet touch the ground
this bike is a geared high torque monster, its a terrible road bike, when your riding at 55 mph the engine is screaming and vibration is severe.
A better alternative would be the Suzuki DRZ400S, this bike has a top road speed of 95 mph, and you can run it like a full motocross bike off road, jump it 30 feet if you want, if you dump it, its light enough you can pick it up yourself, plus has a lower seat height so your feet touch the ground.
