The DeinoChaser is a Snapping Combination between the two Deinonychus Guardian Tribes, the yellow Deinos Tribe and the black Chase Tribe, which when they combine serve as the Kyoryugers' motorcycles. As the DeinoChaser they can reach speeds of 300 km/h and cross any terrain. Separated, they still attack in pairs with their powerful claws.
The D-Racer is Deathryuger's personal motorcycle. Unlike DeinoChaser, it isn't sentient, nor is it summoned with a Zyudenchi.
