The
Yamaha Phazer RTX is powered by a 2 cylinder, 500 cc engine
which is based on the YZ250F engine. Essentially it is
two of them engineered together, resulting in a compact
engine which generates its maximum power at over 11,000
rpm. The Yamaha Phazer RTX is fitted with an electric
starter system.
The Yamaha Phazer RTX uses a Dual Shock CK rear suspension
with an HPG clicker shock. The FX chassis uses a narrow
track and the skidframe is also narrower. The suspension
of the Yamaha Phazer RTX offers a number of unique features,
in addition to the narrowness. The carrier wheels on the
rear upper cross shaft are oversized to improve their
efficiency and reduce friction. The rear mount is built
with a cantilever system to allow the track tension to
remain consistent through the compression travel. The
rear arm has coupling blocks. The front lower shock mount
is on a cam to increase the shock rate through its travel.
The Yamaha Phazer RTX takes many of its cues from other
off-road motorsports, including its sport rider-forward
positioning. It has a tall, narrow seat and tall, forward
handlebars like the dirtbikes.
