The LEGO Racers Vicious Viper (8231-1) prepares for high-speed off-road action, featuring a compact monster truck designed for immediate launch. This 96-piece model showcases an uncovered race engine at its rear, hinting at the power within, complemented by aggressive snake decor along its bodywork. Mounted on massive off-road tires, the Vicious Viper is ready to tackle any terrain. The set’s primary function involves an included air stomper mechanism: load the monster truck onto the stomper, activate the pump, and watch the Vicious Viper blast off the line for real racing action. The finished vehicle measures 14 cm long, 6 cm high, and 7 cm wide, making it a dynamic addition to any Racers collection.
