Here's a fun 'n' zippy radio controlled model of the Yamaha YZ450F motocross motorcycle! Everything you need to run the bike is included here. Bike moves forward, turns left or right, brakes, and even backs up! A two-hour charge of the batteries (charger included) gives you about 15 minutes of running time. Intended for indoor use. The radio control system is good up to 10 meters. Set includes a test-use 9-volt battery for the transmitter. A gyro system in the rear wheel gives this little guy super stability! Set includes the motorcycle, display stand, radio control transmitter unit, battery charger, 9-volt test battery, instruction booklet, and five traffic cone pylons to practice your slalom driving. This bike is yellow and driver is red, and the RC system operates at 31MHz.
