Allan Brown is in charge of Nicoletti’s powerplant. He
worked with Crower to regrind the cams and installed a
13.5:1, high-compression Wiseco piston. Crank Works
weighted and balanced the cranks for more rpm. The team
uses TiFuel T4-U fuel, and many of the parts in Phil’s engine
are available to the consumer.
There are no factory Yamaha parts on the N-Fab/TiLube
bike, but Nicoletti and his teammates do use works Kayaba
suspension. Phil used the KYB Pneumatic Spring Fork in
Supercross, and the team intends to run PSF air technology
outdoors. Kayaba and Enzo handle valving changes and
rebuilding the suspension.
The team relies on Akrapovic exhausts to boost power. Not
surprisingly, Nicoletti’s YZ450F boasts a full-blown titanium
system. Race teams are always in search of increased
performance and reduced weight. The Akrapovic exhaust,
which has been a favorite of the MXA wrecking crew, does
both. A large resonance chamber is located very close to the
exhaust port on the head pipe. This system passes the FIM
two-meter-max sound test with flying colors.
Phil Nicoletti’s suspension settings are fairly similar to his
teammates’. An eagle-eyed reader will notice the words
“Blose Test” written on top of the shock. Phil likes the
combination of a stiff fork and a soft shock—a common
setup among fast Pros. Nicoletti is most picky about ride
height and his subframe. The team offers two different-length, cut subframes—4mm or 8mm—to give their riders
a bit more clearance.
