The 2003 FourTrax Foreman Rubicon features a powerful
500cc engine and the revolutionary Hondamatic transmission.
It is a continuously variable automatic transmission
that provides quiet, maintenance-free operation
in a compact, rugged design. Riders seeking a reliable
automatic transmission with the power and durability
of a Honda will find the FourTrax Foreman Rubicon
to be the most versatile ATV available anywhere.
Features & Benefits
Honda's first liquid-cooled four-stroke ATV
engine is a single-cylinder 499cc overhead-valve
design that provides tremendous torque and dependable
Hondamatic(tm) transmission is a continuously
variable, hydro-mechanical design that eliminates
belts altogether. It is compact, quiet, maintenance-free
and very rugged. The Hondamatic features true
engine braking, unlike conventional belt-drive
Full-time four-wheel drive and a unique torque-sensing,
front differential provide superior traction
compared to conventional limited-slip designs,
and reduces torque steer substantially for less
Extensive weight-saving measures keep the FourTrax
Foreman Rubicon's dry weight at 600 pounds.
Liquid-cooled overhead-valve single-cylinder
499cc four-stroke engine is mounted longitudinally
in the frame, allowing direct drive-shaft alignment
to front and rear wheels for improved drivetrain
Liquid-cooling provides consistent engine operating
temperature in extreme conditions for maximum
power output and long engine life.
Camshaft is located adjacent to the cylinder
head, reducing engine height. Together with
the external engine-oil tank, engine height
is further reduced for a low center of gravity
and excellent handling.
Four-valve cylinder head utilizes two short
pushrods to provide a broad powerband for optimum
performance and engine efficiency.
Unique dry-sump oiling system attaches the oil
tank to the front of the engine cases, lowering
engine height and allowing optimum engine placement
for excellent ground clearance and superb handling.
Standard high-flow oil cooler assures optimal
engine lubrication under difficult operating
The multiple scavenging oil system utilizes
an oil pump with three sintered steel rotors
(one for feed, two for scavenge) to provide
a stable oil supply in diverse riding conditions.
Unique temperature indicator uses two sensors
to monitor both oil and coolant temperature.
High-capacity coolant radiator is rated at 17.2
kW for efficient engine cooling in extreme operating
Compact, flat-shaped radiator fan motor is lightweight
and contributes to optimum engine placement.
Rubber-cushion engine mounting and gear- driven
counterbalancer reduce vibration.
Integral electric carburetor heater system improves
driveability and ensures smooth operation in
Convenient electric starter, with auxiliary
recoil starter and an automatic internal decompression
Solid-state CD ignition with electronic advance
for excellent performance and reliability.
Stainless steel exhaust system provides superior
Closed crankcase vent system safeguards against
engine oil contamination.
Hondamatic transmission utilizes variable hydraulic
pressure and mechanical torque amplification
to provide seamless job-handling power and excellent
acceleration. Engine power drives a hydraulic
pump. The pump, in turn, drives a hydraulic
motor with variable fluid capacity. Utilizing
pump and motor pistons and a variable-pitch
motor-side swash plate, hydraulic capacity and
pressure are varied, producing continuously
variable output speed. In addition, torque is
increased as output-shaft speed is reduced.
Dash-mounted knob switches to one of three electronic
shifting programs: D1 for maximum performance,
D2 for maximum torque, and ESP(tm), Honda's
exclusive Electric Shift Program(tm). D1 and
D2 modes provide continuously variable transmission
output; ESP allows the rider to "shift" the
Hondamatic with the touch of a thumb using two
push-buttons mounted on the left handlebar.
The Hondamatic is extremely efficient, with
operating efficiencies ranging from 75-81 percent
in full-reduction mode and from 87-92 percent
when input and output speeds are the same (1:1
The Hondamatic transmission is compact and maintenance-free,
with no belts to wear out and replace.
The Hondamatic is fully sealed and impervious
to external contamination.
The Hondamatic features true engine braking,
unlike conventional belt-drive designs.
Versatile rider controls provide a shift lever
to select Drive, Low, Neutral, and Reverse.
The Hondamatic uses multi-filtered (one large-capacity
filter and three strainers) engine oil as hydraulic
fluid, simplifying maintenance and ensuring
an adequate oil supply in all operating conditions.
Rugged frame and suspension provide an exceptional
10 inches of ground clearance.
Steering mechanism design features light effort
and a tight turning radius of 10.8 feet.
Independent double-wishbone front suspension
uses premium shock absorbers to provide 6.7
inches of suspension travel for a plush, comfortable
Steel swingarm and dual rear shock absorbers
provide 6.7 inches of suspension travel for
superb comfort and compliance.
Attractive, large-diameter 12-inch aluminum
wheels reduce unsprung weight for excellent
ride and handling.
25 x 8-12 front, 25 x 10-12 rear tires provide
added ground clearance while maintaining precise
Triple-sealed front hydraulic drum brakes and
sealed rear mechanical drum.
Engine design produces low emissions and meets
California Air Resources Board (CARB) off-road
