FX350 MY23
With the agility of a 250 and a 450-rivalling power-to-weight ratio, the FX 350 strikes a competitive balance between power and handling. This appeals to both professional and amateur riders alike, as a user-friendly riding experience is guaranteed in all conditions. With considered revisions to the engine and chassis for 2023, together with advanced electronics to further enhance performance, the FX 350 is a highly capable off-road machine. Complete with a new, Swedish-inspired white, yellow, and grey colour scheme, which is applied to redesigned bodywork, the striking aesthetics, improved ergonomics, and flatter seat profile clearly indicates the continued development of the FX 350.
Engine
The new FX 350 engine is designed to deliver maximum
performance. For 2023, the repositioning of all major
engine components and shaft arrangements enhances
overall handling with the design improving anti-squat
behaviour from the whole chassis. The engine is tilted
two degrees backwards and is 8 mm shorter in height to
further centralise mass. Weighing just 59.9 lb, the new
350cc 4-stroke engine produces a higher and more
usable power output.
Gearbox
Produced by PANKL RACING SYSTEMS, the 6-speed
gearbox is designed to be extremely light and durable
with optimised gear ratios.
Lightweight Frame
The proven chromium molybdenum steel frame is refined
for 2023 to reposition rotational masses inside the
engine which together with a new shock mounting
position, significantly improves anti-squat behaviour of
the chassis. With optimised wall thickness in high-stress
areas improving reliability, the frame continues to offer
advanced geometries and flex characteristics aimed at
providing unparalleled rider feedback, energy absorption,
and exceptional straight-line stability. The frame is
finished off in a premium metallic blue powder coating
with redesigned standard frame protectors offering
superior protection, durability, and grip in any condition.
Additionally, the inclusion of forged brackets on the
lower frame rails allows for easy installation of the
standard skid plate.
WP XACT Front Suspension
The 48 mm split air WP XACT forks now offer improved
bottoming resistance thanks to a new hydrostop, which
applies a progressive damping force in the last 40 mm of
travel for even greater comfort. The WP forks are
designed with a capsulated, adjustable air spring and
pressurized oil chamber for smooth action and
consistent damping. Oil and air bypasses reduce
pressure peaks and in combination with a midvalve
damping system, the forks provide precise feedback to
the rider. The settings are easily adjusted via the single
air pressure pre-load valve, as well as through easy
access click adjusters for compression and rebound. For
improved durability, new fork protection rings prevent dirt
intrusion. Additionally, the air pump needed to adjust the
fork’s air pressure is provided as standard
Brembo Hydraulic Clutch and Braking Systems
The high-performance Brembo hydraulic clutch system
guarantees even wear, near maintenance-free operation
and perfect modulation in every condition. Meaning that
play is constantly compensated so that the pressure
point, and function of the clutch remain identical in cold
or hot conditions, as well as over time. Countless hours
of race-focused testing have proven the high-quality,
Italian-made Brembo hydraulic systems exceptional
reliability.
he highest level of quality is guaranteed with class-
eading Brembo callipers made from single pieces of
aluminum for strength at the lowest possible weight.
Together with a 260 mm front and a 220 mm rear disc
removing dirt efficiently, superior stopping power and
braking confidence is guaranteed in all conditions.
Technologically Advanced
A redesigned and intuitive handlebar-mounted map
select switch allows riders to activate launch and traction
control, and allows riders to toggle between two engine
maps. The easy-to-operate map select switch allows
racers to quickly alter and set up the engine
characteristics on a race by race basis dependent on
track conditions and rider preference.
Traction control on the FX 350 is engaged by a button
marked ‘TC’ on the Map Select Switch and functions by
analysing throttle input from the rider and the rate at
which engine RPM increases. If the RPM increases too
quickly, the engine management system (EMS) registers
a loss of grip and reduces the amount of power to the
rear wheel to ensure maximum traction. This is a distinct
advantage in wet or muddy conditions.
