Rincon RedFourTrax Rincon

Meet the SUV of ATVs--the ground-breaking 2003 FourTrax Rincon. The world's most comfortable full-size ATV is feature-laden with a powerful liquid-cooled 650 engine, an all-new fully automatic transmission, TraxLok selectable 2WD/4WD, a torque-sensing front differential and fully independent front and rear suspension.

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 power.
  • Honda's first automotive-style automatic ATV transmission draws power through a hydraulic torque converter to drive three forward gears and reverse.
  • 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 mode.
  • * The FourTrax Rincon(tm) features Honda's first fully independent ATV rear suspension for comfortable cruising over the toughest terrain.
  • 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 efficiency.
  • 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 handling.
  • 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 cold conditions.
  • CD ignition with electronic advance for excellent performance and reliability.
  • Engine design produces low emissions and meets California Air Resources Board (CARB) off-road emissions standards.
  • Stainless steel exhaust system provides superior corrosion resistance.
  • 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 conditions.
  • 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 conditions.
  • 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 effort.
  • 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 belt-drive designs.
  • 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 handlebar.
  • A handlebar-mounted control switches the automatic transmission between ESP mode and automatic operation.
  • A convenient column-style shift lever permits the rider to easily select Drive, Neutral or Reverse.


  • 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 vehicle weight.
  • 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 ride.
  • 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 overall handling.
  • 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 ground clearance.
  • SUV-type radial tires provide a smooth ride and exceptional handling. Tough, large-diameter 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.

Additional Features

  • Multi-function LCD digital instrumentation is compact, 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 lever.
  • Convenient electric starter, with a lightweight auxiliary recoil starter and an automatic internal decompression system.
  • A tough rubber cover protects the gearshift button from dirt, water and mud.
