Features & Benefits
Unique FourTrax Rincon Features
Honda's largest liquid-cooled four-stroke ATV
features a single-cylinder 649cc OHV engine
that provides tremendous torque and dependable
Honda's first automotive-style automatic ATV
transmission draws power through a hydraulic
torque converter to drive three forward gears
TraxLok(tm) enables the rider to shift between
2WD and 4WD with a simple thumb-operated switch.
A torque-sensing front differential reduces
torque steer for low steering effort in 4WD
* The FourTrax Rincon(tm) features Honda's first
fully independent ATV rear suspension for comfortable
cruising over the
Extensive weight-saving measures include the
use of aluminum for the following components:
forged front upper control arms, rear upper
and lower control arms, rear knuckles, front
and rear wheels.
Exciting SUV styling features flowing fenders
with integrated headlights and taillights.
Liquid-cooled overhead-valve single-cylinder
649cc 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 semi-dry sump, engine height is further
reduced for a low center of gravity and excellent
Four-valve cylinder head with two short pushrods
provides a broad powerband for optimum performance
and engine efficiency.
Nickel silicon carbide (Nikasil(r)) plated cylinder
lining is lightweight and more durable than
conventional steel-sleeve cylinders.
Snorkel-type air intake system is specially
designed for water crossings.
* 37mm constant velocity (CV) carburetor features
a unique ribbed float that minimizes fuel sloshing
when riding over rough terrain, minimizing the
evaporation of unburned hydrocarbons.
Integral electric carburetor-heater system improves
driveability and ensures smooth operation in
CD ignition with electronic advance for excellent
performance and reliability.
Engine design produces low emissions and meets
California Air Resources Board (CARB) off-road
Stainless steel exhaust system provides superior
Unique semi-dry-sump oiling system locates the
oil tank inside 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 20.2
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 system and gear-driven
counterbalancer reduce engine vibration.
Closed crankcase vent system safeguards against
engine oil contamination.
TraxLok is easily engaged with a simple thumb-switch
on the right handlebar. An electromagnetic mechanical
clutch unit (EMCU) located on the center of
the propeller shaft engages 4WD with a quiet
two-way roller clutch. Unlike mechanical designs,
TraxLok ensures smooth operation by employing
a magnetic switching mechanism that engages
when front and rear wheel speeds vary by less
than 6 mph.
A unique torque-sensing torque-sensing front
differential provides superior traction compared
to conventional limited-slip designs and reduces
torque steer substantially for less steering
The rear drive-shaft joins the rear final-drive
gearcase at a 77¡ angle, eliminating the weight
and complexity of an additional shaft and joints.
The design also contributes to the Rincon's
considerable 8.0 inches of rear wheel travel.
Honda Automatic Transmission
The automotive-style Honda automatic transmission
features a hydraulic torque converter, three
hydraulic clutches and an electronic control
unit (ECU) to automatically select one of three
forward gears and one reverse gear. The ECU
monitors throttle opening, vehicle speed, engine
rpm, gear selector position, brake application
and engine oil temperature.
The Honda automatic transmission shifts electronically--eliminating
unsightly and trouble-prone vacuum lines--and
features engine braking, unlike conventional
The Honda automatic transmission features a
filtration system to protect against external
contamination. The compact and maintenance-free
design means there are no belts to wear out
and replace. Using multi-filtered engine oil
as hydraulic fluid, the design also simplifies
maintenance and ensures an adequate oil supply
in all operating conditions.
An Electric Shift Program(r) (ESP(r)) allows
the rider to manually select gears by simply
pressing two push-buttons mounted on the left
A handlebar-mounted control switches the automatic
transmission between ESP mode and automatic
A convenient column-style shift lever permits
the rider to easily select Drive, Neutral or
A rugged steel perimeter frame and four-wheel
independent suspension provide an exceptional
10.0 inches of ground clearance.
A separate rear frame utilizes the final-drive
gear case as a stressed member, reducing overall
The Rincon's steering mechanism design allows
a light steering effort and a tight turning
radius of 10.8 feet.
Independent double-wishbone front suspension
uses premium shock absorbers to provide 6.9
inches of suspension travel for a plush, comfortable
Honda's all-new independent rear suspension
uses a double-wishbone design and features forged
aluminum knuckles and upper/lower A-arms to
substantially reduce unsprung weight. The rear
knuckle pivots use lightweight metal bushings
in place of conventional ball joints and radius
arms, eliminating toe-in as the rear suspension
travels through its stroke. This simple design
maintains rear wheel alignment and further reduces
unsprung weight, contributing to responsive
Lightweight single-tube gas-charged rear shocks
and an anti-sway bar provide plush, well-controlled
damping throughout the Rincon's exceptional
8.0 inches of wheel travel.
Triple-sealed front hydraulic drum brakes are
virtually impervious to dirt and water.
A new rear center hydraulic disc brake and self-adjusting
mechanical rear parking brake are mounted on
the rear propeller shaft, further reducing unsprung
weight and contributing to the Rincon's considerable
SUV-type radial tires provide a smooth ride
and exceptional handling.
25 x 8-12 front tires and 25 x 10-12 rear tires
provide added ground clearance.
Attractive SUV-style large-diameter 12-inch
aluminum wheels further reduce unsprung weight
and contribute to superb handling.
Multi-function LCD digital instrumentation is
tough and waterproof,
featuring large readouts for gear selector position,
speedometer, odometer, resettable tripmeter
and hourmeter/clock. Instrument housing includes
LED lights for Drive, Neutral, Reverse and temperature
warning indicator. A fuel gauge located within
the instrument housing comes as standard equipment.
Durable, comfortable, easy-to-use controls include
a keyed ignition switch for added security,
parking brake and a handlebar-mounted choke
Convenient electric starter, with a lightweight
auxiliary recoil starter and an automatic internal
tough rubber cover
protects the gearshift button from dirt, water
