The Machine Kivaa (マシンキバー, Mashin Kibā) is Kiva's personal motorcycle, also known as "Crimson Iron Horse (真紅の鉄馬, Shinku no Tetsu Uma)" given by Kivat and is said to have been made by Motobat the 16th (モトバット16世, Motobatto Jūrokusei), master craftsman of the Kivat Race. The Kivaa is a living motorcycle, possessing the brain of a horse creature in its upper cowl. When running at high speed, it generates the Shadow Veil (シャドーベール, Shadō Bēru) to hide itself from plain sight. The Kivaa can be powered up through the use of the Buroon Fuestle.[1]
Design[]
The Machine Kivaa has the following parts:
- Sonic Wing (ソニックウイング, Sonikku Uingu) - A sensory organ that communicates with Kiva by emitting ultrasonic waves. Even if the triangle eye is destroyed, it can still propel itself if this part remains.
- Triangle Eye (トライアングル・アイ, Toraianguru Ai) - A visual organ that is embedded with three magic stones called White Gemstone (白輝石 (はっきせき), Hakki Seki), which illuminates the darkness as if it's midday to ensure the passenger's view, and also becomes the eye of the Machine Kivaa during automatic driving.
- Bloody Face (ブラッディフェイス, Buraddi Feisu) - An upper cowl with a control center for Machine Kivaa. It contains the brain of a Horse Fangire which follows Kiva's intention. It is possible to drive with Kiva's willpower.
- Spirit Steer (スピリット・ステア, Supiritto Sutea) - A device that communicates Kiva's intentions to the machine via his hands. The machine will run semi-automatically, even if Kiva is not actively controlling.
- Kiva Stamp (キバの刻印, Kiba no Kokuin) - An emblem indicating it is an ally of Kiva. Among monsters, it is known as the emblem of those with power, and just like the choker on Kiva's neck, some monsters freeze in fear when they see this emblem.
- Bloody Converter (ブラッディコンバーター, Buraddi Konbātā) - An energy storage and conversion device that stores the natural energy collected from the Claw Feeler and converts it into Demonic Power and sends the energy to Bloody Heart.
- Bloody Ladder (ブラッディラダー, Buraddi Radā) - This is a device to improve the stability of the vehicle when the Machine Kicker shifts to ultra-high speed mode. Two White Gemstones are embedded inside, which also function as the rear eye.
- Doran Ring (ドランリング, Doran Ringu) - Ultra-high grip tires made from GaoraDoran's belly leather similar to Kiva's suit. With a fully solid construction and supple GaoraDoran leather, this tire can firmly grip the ground, absorbs shock and doesn't puncture.
- Sylvania Absorber (rear) (シルバニア・アブソーバ (リア), Shirubania Abusōba (Ria)) - Like the Front Fork, the rear shock of the Machine Kivaa is processed with silver Trysylvania, which improves road following ability and suppresses the destructive runaway of the Demonic Power.
- Bloody Heart (ブラッディハート, Buraddi Hāto) - A supernatural power unit that amplifies the power of the Demon Emperor sent from the Bloody Converter and creates power for the Machine Kivaa. Two red Demon Emperor Stones are built into the front and rear cylinders, and resonate with each other to create power. The surface is coated with silver Trysylvania to suppress the runaway of the Demonic Power.
- Claw Feeler (クローフィーラー, Kurō Fīrā) - A device that catches energy in the atmosphere and sends it to the Bloody Tank. At the same time, a Shadow Veil is generated.
- Sylvania Absorber (front) (シルバニア・アブソーバ (フロント), Shirubania Abusōba (furonto)) - The machine forkbar's front fork is made of Trisylvania silver to improve road following ability and at the same time suppress the destructive runaway of the Demonic Power.
- Sylvania Exap (シルバニア・エクザップ, Shirubania Ekuzappu) - A device that discharges the surplus power of the Demon Emperor amplified by the Bloody Heart and prevents self destruction. It has the role of stabilizing the power of the Machine Kivaa by efficiently exhausting power.

The Buroon Booster (ブロンブースター, Buron Būsutā) combines the creature Buroon with the Machine Kivaa, increasing its abilities by adding Buroon's armor to it. Buroon gives the Machine Kivaa extra armor and exhaust ports, increasing its speed and power significantly and providing Kiva with a powerful vehicle and combat machine. When running at high speed, it generates the Air Break Field (エアブレイクフィールド, Ea Bureiku Fīrudo) with the Shadow Veil and reduces air resistance to almost 0.[2]
