The Mach Driver Honoh (マッハドライバー炎) is Kamen Rider Mach and Kamen Rider Chaser's belt, which they use to transform into their rider forms via the Signal Bikes. It was invented by Harley Hendrickson.

Origin
The Mach Driver Honoh was designed to someday be a successor to the Drive System. It is programmed with an A.I. to handle the tasks Krim does to the Drive System, and as such, boosts the effectiveness of Mach, though this deals a heavier toll on the user's body compared to Drive's as a result. Professor Hendrickson would have had more time to tone this issue down, had Go not run off mid-training with the Mach Driver Honoh and Signal Bikes back to Japan.

Functionality
To transform, the user raises the Signal Landing Panel (シグナルランディングパネル) and inserts a Form Signal Bike into it, causing the Mach Driver Honoh to announce "Signal Bike" (シグナルバイク). Once the Signal Bike is set, the user must push the Signal Landing Panel back down to finish the transformation sequence into either Kamen Rider Mach or Kamen Rider Chaser, right after the Mach Driver Honoh announces "Rider" (ライダー) and the corresponding form used. The Signal Bikes that assume Mach and Chaser's default forms can only be used until transformed.

After transforming with a Form Signal Bike, the user has the option to switch between different other Signal Bikes. To do so, the user must raise Signal Landing Panel, pull the used Signal Bike out, insert the selected Signal Bike back into the Signal Landing Panel, and push it back down. This would change the base Kourin Signal from either Rider, or any previous Kourin Signal used before, and cause the Mach Driver Honoh to announce "Signal Koukan" (シグナル交換) and then the corresponding Signal Bike used.

Much like the Shift Brace, the user is able to use any special abilities tied to the Signal Bikes currently in the Mach Driver Honoh by hitting the Boost Igniter (ブーストイグナイター) button on the belt up to four times. Mach can also summon the Zenrin Shooter by hitting the Boost Igniter four times.

The Mach Driver Honoh also works with the Shift Cars, activating special Kourin Signals tied to that Shift Car. When a Shift Car is inserted into the Signal Landing Panel, it causes the Mach Driver Honoh to announce "Shift Car" (シフトカー). Afterwards, once the Singal Landing Panel is pushed back down, it announces "Tire Koukan" (タイヤ交換) and then a Japanese word related to the ability of the corresponding Shift Car used. Like with Drive, if the Shift Car that is being used happens to possess a Tire Specific Item, Mach or Chaser can wield it.

When activating a Shift Car-related Kourin Signal, the sound effects played would be a mix of the Mach Driver Honoh's sounds and the Drive Driver's sounds for that Shift Car. If the Shift Dead Heat Car is inserted into the Signal Landing Panel, it causes the Mach Driver Honoh to announce "Signal Bike, Shift Car" (シグナルバイク, シフトカー) as an indication of Shift Dead Heat being a hybrid form of the two miniature vehicles.

To initiate a finishing attack, Mach or Chaser must raise the Signal Landing Panel and press the Boost Igniter, which makes the Mach Driver Honoh announce "Hissatsu" (必殺). Pushing the Signal Landing Panel back down afterwards would then give Mach or Chaser an exceeding amount of power, as well as cause the Mach Driver Honoh to announce "Full Throttle" (フルスロットル) and then the corresponding Signal Bike used. Mach or Chaser may now release the power gained in any way they wish.

In order to have the Mach Driver Honoh cancel the transformation, Mach or Chaser must raise the Signal Landing Panel, remove the Signal Bike currently placed in the Mach Driver Honoh, and push the Signal Landing Panel back down. This causes the Mach Driver Honoh to announce "Otsukare" (オツカーレ).
