KTM Throttle Body Kit

KTM throttle body upgrade kit for your Yamaha YFZ450R. Includes everything you need to complete the throttle body swap except a Vortex ECU. A Vortex ECU with KTM throttle body mapping is required to run this kit. If you need a Vortex ECU click here to browse our options!

Here’s why-

• Improved throttle response
• Improved power delivery
• More horsepower
• Simpler than the OEM throttle body
• Easier maintenance
• Cleaner engine bay
• Easier to install and remove

Included in kit-

• Complete throttle body
• Pressure sensor adapter
• Fuel line and 45° quick coupler to reduce pressure on fuel tank spigot
• TPS and Injector electrical adapters
• OEM Yamaha throttle cable
• Modified OEM cylinder head boot for proper fitment
• High idle block plug (can request to keep the original high idle feature if wanted)
• Optional softer throttle spring
• Free 38 Motorsports ECU flash included - normally a $150 service!

VORTEX ECU REFLASH IS REQUIRED and is included in this kit. If you already have a Vortex ECU that you plan to use, you will need to send it in to us for the updated mapping unless you plan to get a dyno tune or have another tuner flash your ECU. If you are purchasing a new Vortex ECU through us in conjunction with this kit, please choose the "Basic Tune" option as all mapping required to run this throttle body is included free of charge in our KTM throttle body kit.
