and cornering performance while out the
rear the KYB shock gets revised damping
characteristics to match the updated chassis.
Improved braking performance is achieved
with newly engineered lighter front and rear
brake calipers, larger surface area brake pads,
and redesigned front (270mm) and rear
(240mm) discs.
Wireless tuning again makes an appearance via
onboard wireless connectivity through Yamaha
Power Tuner App. Once settings are dialled-in,
riders can then choose between two userdefined
ECU maps on the fly via the handlebarmounted
dual-mode engine map switch.
“ALSO NEW FOR 2021, THE YZ250F AND
YZ450F WILL BE OFFERED IN SPECIAL
MONSTER ENERGY YAMAHA RACING
EDITIONS BRINGING EVERYDAY RIDERS
ACCESS TO A FACTORY RACE TEAM-INSPIRED
AESTHETIC OFF THE DEALERSHIP FLOOR
YZ450FX
The 2021 YZ450FX features a new 449cc,
liquid-cooled, four-stroke, electric start engine
with an all-new compact cylinder head with
redesigned combustion chamber shape, and
steeper valve angles.
The rearward-slanted cylinder houses a higher
compression piston with low friction rings
attached to a longer connecting rod. The
transmission has been refined to provide
smoother shifting, and a more efficient crank
breather system has been adopted to decrease
pumping losses. In all, the lighter, more compact
engine produces increased power across the
entire RPM range for stronger and more linear
pulling power.
The latest evolution of Yamaha’s lightweight
aluminium bilateral beam frame has been
redesigned with all-new flex characteristics
that provide improved cornering performance,
traction and bump reaction to give the rider
more confidence to push harder in any offroad
condition.
Other chassis components such as engine
mounts, top triple clamp and front axle, as well as
the class-leading KYB suspension with enhanced
compression and rebound characteristics, have
been refined to reduce weight while improving
handling and performance.
To bring the new package to a stop, the 2021
YZ450FX features a newly designed front brake
caliper, brake pads and front and rear disc. The
combined changes to the new 2021 YZ450FX
deliver increased power output with more
controllable, linear acceleration and lightweight
handling characteristics that mimic the YZ250FX.
To further showcase the YZ450FX’s cross
country edge, electric start, a lightweight lithium
battery, and advanced fuel injection are all
standard features. The front-positioned intake
and rear-positioned exhaust layout deliver the
widest spread of reliable power while balancing
the weight for excellent mass centralisation
The 450FX also scores Yamaha’s dual-mode
switchable engine mapping and wireless
connectivity through the Yamaha Power Tuner
App. This is in addition to the Yamaha Launch
Control System.
