This is our new power kit for the 2023+ YZ450F and 2024+ YZ250F.

The kit consists of:

-RP Race Dual Injector throttle body with custom setup

-Vortex ecu with Custom TD mapping

This is the setup designed and tested with ClubMX RaceTeam. This kit adds power everywhere from the crack of the throttle all the way to overrev, but allows for a very smooth tunable powerband allowing the rider to use the power in these engines to their fullest potential. 

This kit does require you to remove some parts from your oem Yamaha throttle body (throttle spring and throttle cam as well as the tps) we will install all the parts here at Twisted development if you send in your stock throttle body.  If you are capable of setting the tps voltage yourself the installation is a breeze
