WHAT IS IT? This Yamaha YZ250 pipe was developed
by Bud Racing and made by the Netherlands-based
company HGS. As for the carbon silencer, Bud Racing
made and developed this work of art in France.
WHAT’S IT COST? $249.00 (pipe), $119.00 (carbon fiber

WHAT STANDS OUT? Here’s a list of things that stand
out with the Bud Racing pipe and silencer.
(1) Installation. With the Bud Racing YZ250 pipe and
silencer, all the OEM hardware is transferred over. Before
installing the pipe, make sure to take the O-ring out of the
OEM pipe and inserted it into the Bud Racing pipe. Do
not race without the O-ring—it is important. Installing the
pipe was a breeze. We didn’t even have to move the
two adjustable brackets to line up the Bud Racing pipe
brackets. It was a five-star fit. As for the sleek carbon
fiber silencer, it has one variable bracket that lines up
with a simple adjustment. Keep in mind that the stock
silencer has two mounting brackets, whereas the Bud
Racing silencer has one, so don’t forget to put the bolt
back into the top mounting area. At first we thought we
could trim a few grams by not using the bolt, but that
bolt holds the right side of the rear fender in place. We
think the long bolt is an eyesore, so we replaced it with
one half the length.
( 2) Stock trim. The Yamaha YZ250 is one of the most
loved bikes in MXA’s arsenal. It won our 250cc two-stroke
shootout, but the powerplant has been growing long in
the tooth for almost a decade. Why change something
that is loved by so many, right? We love the smooth
powerband of the YZ250, but it lacks horsepower
compared to its competition. In a straight line, the YZ250
would be the caboose on the 250 two-stroke freight train.
Why does a drag race matter? Because starts matter. If
you are a racer, the YZ250 powerplant will struggle to
get you to the front in the first corner. We want more
( 3) Performance. We want to give Bud Racing a
round of applause. The Bud Racing exhaust system
silenced the wrecking crew’s complaints about the
YZ250’s powerplant. No more abusing the clutch out of
corners to get up to speed. There was increased power
from low to mid, and the top end got some extra over-rev. Throttle response was also improved. Off the very
bottom, the power was a bit sluggish, but it livened up
quickly (and what are you doing lugging a two-stroke?).
Yamaha, if you want to make us happy, copy the Bud
Racing pipe and silencer for 2016.
( 4) Tuning. Race gas? No need! Jetting? If it runs well
with the stock exhaust, you should be free and clear of
changing those pesky jets. The only thing we played with
was the air screw.
( 5) Options. Bud Racing also offers an aluminum
silencer with a carbon tip at the same price. We
suggest this silencer if you are looking for increased longevity. We have not had any issues with the Bud Racing
full-carbon silencer, but our past experiences have taught
us that aluminum lasts much longer than carbon fiber.
WHAT’S THE SQUAWK? We have three quibbles. (1)
With the silencer mounted to one of two mounts, it is
not a super-secure fit. ( 2) The top bolt that used to hold
the silencer and fender now sticks out like an eyesore.
( 3) Bud Racing does not include an O-ring with the pipe.
This is not an issue unless your OEM O-ring is damaged.
We wish that the Bud Racing pipe
BUD RACING 2015 YZ250 PIPE & SILENCER
came stock on the YZ250.
