factory Honda’s off-road efforts for years. Burson also runs
Fasst Company Flexx handlebars, which use a patented
design of fiber bushings and elastomers at the pivot points
to reduce energy transfer to the rider.
To complete any off-road race machine, there is a host
of bolt-on aftermarket items that are used, and Burson’s
Purvines/DA8 Training Yamaha YZ450FX is no exception.
IMS’ 3.1-gallon oversized tank provides added fuel capacity and is fitted with a dry-break system for fast pit stops.
The team also uses IMS’ Core pegs that have a wider,
more aggressive platform than stock. The stock seat is
trimmed to accept the new fuel-tank filling system, and
then a Seat Concepts gripper cover is used.
In off-road racing, the machine and rider take a beating,
so protection is key. Burson’s YZ450FX is equipped with
an AXP full-coverage skid plate, Works Connection radi-
ator guards, BRP rear chainguide, FMF carbon fiber heat
shields and Acerbis handguards to protect Nick’s delicate
hands. Protection from those high-speed head-shake
situations is provided via GPR’s Version 4 Pro stabilizer
kit. The Version 4 stabilizer is mounted under the han-
dlebar, and the Pro mounting kit includes the entire top
triple-clamp assembly. The entire team uses Dunlop AT81
off-road tires with foam mousse inserts for flat prevention.
WHAT WE THINK
Testing a rider’s race machine is way different from
testing a project bike that we build. In one instance we are
getting a feel for what that individual likes, and in another
trying to make a bike better for a particular application
than it was stock.
Burson’s bike surprised us in a couple areas: His overall
setup is pretty neutral—no crazy-low or high-hand-control
positioning, weird ergonomics or unrideable power. We
actually liked it and were comfortable on Burson’s race
machine from the start. With that being said, it’s definitely
softer suspension-wise than we were expecting, and it’s a
bit choppered out, but that’s to be expected with the type
of racing Burson does. Power delivery was very manageable and actually not drastically different from stock—just
refined in some areas for the better.
