Back in August of 2024 we tested Phil Nicoletti’s full ClubMX Yamaha race machine that was too much for my vet hands to handle. However, within that test there was a secret to Phil’s bike that we uncovered that he wasn’t too willing to talk about. When we wanted to ask him about this secret throttle body that he was running on his race bike, he brushed over it and wanted us to keep moving on, so we knew we had to deep dive this specific part more. Sorry, Phil! Even though Phil’s bike was a full race engine done by Twisted Development we wanted to grab Jamie Ellis (owner of TD Racing), give him our completely stock 2025 YZ450F, and have him bolt on just the RP throttle body to see if this dual injected system can smooth out the blue beast that is the YZ450F.
