Superbikes might seem fun but their a great way to leave your brain on the asphalt.  If you want to ride on two wheels but are looking for something a little more tame, the Suzuki TU250X Motorcycle ($4,000) is a good start. The TU250X sports a stylish retro design, a 249cc four-stroke SOHC engine, a five-speed transmission, a diamond-shaped steel tube frame, front disc and rear drum brakes, and a low 30.3-inch seat height.  An all around great bike for beginners or those looking for a classic ride.
