The Honda Rincon is one of a newer style of All-terrain vehicle (ATV) known as Sport/Utility models.

Previously ATV's came in either the more common utility variety that is very popular for use on farms or the sports/racing models. The utility models are larger, have racks for carrying equipment, and full coverage fenders to keep the rider dry. They are usually slower than their sports counterparts but many models offer 4x4 and are capable of covering very rough terrain. Sports models often have no fenders, sit much lower, and are designed for all out speed most commonly associated with tracks and smoother terrains where their top speeds can be utilized. However in the past years ATV'ing has become one of the fastest growing sports in the world. Outdoor Adventures Magazine stated in 2003 that with the increase in fuel prices that ATV's are on the verge of overtaking boating as one of the most popular summer powersports-type outdoor activities sighting that many ATV's can run all day on only a few gallons of fuel.

In recent years with the boom in popularity many have been drawn to ATV's yet wanted faster speeds and more sporty handling than offered by the utility type ATV's, yet at the same time found the lack of storage space, less comfortable riding characteristics, and increased danger of the sports models to be a negative. Manufactures began to realize an untapped market by combining the size, comfort, storage, power, ease of riding, and safety of the utility models with the more agile handling, speed, and some of the sportiness of the sports models and the hybrid Sport/Utility models were born. They usually have many available options and accessories and are well designed for all-day riding comfort.

Rincon Generation 1 (2003-2005)

Honda introduced the Rincon as their new top-of-the-line ATV. The Rincon is the head of their FourTrax lineup and utilizes Honda's largest ATV liquid-cooled four-stroke engine, A first for any ATV is the use of an automotive-style automatic 3 speed transmission which shifts either automatically or can be switched on the fly to sport-shift manual mode that Honda calls ESP. Also utilized were Radial Tires based on popular SUV styles. A center hydraulic disc brake system mounted on the rear output shaft, and the first fully independent rear suspension system ever used by Honda. Also included was Traxlok, enabling riders to switch between 2WD and 4WD modes with a simple thumb-operated switch, the Electric Shift Program (ESP) that allows shifting by simply pushing large up/down buttons using the left thumb, and a torque-sensing front differential that reduces torque steer for lighter steering effort in 4WD.

The 2003 Rincon officially known as the TRX650 quickly became very popular and was dubbed the "Cadillac of ATV's" by ATV Enthusiast Magazine, a nickname that stuck. Part of the Rincon's popularity is due to the all-day comfort provided by the ergonomically designed dual density foam used in the seat, the very light and easy steering requiring less effort to turn and control than virtually any other ATV on the market at the time, the intuitive controls that even first-time operators find simple and easy to understand, and reliability. One magazine noted that the new automotive style automatic transmission eliminated the belts used by every other manufacture allowing the Rincon to negotiate deeper water where the belts on most ATVs would become wet and begin slipping. This particular feature has made it very popular with the 20-Something's who use them for driving through sometimes surprisingly deep mud and water with only very minor modifications, though not endorsed by Honda themselves.

Available beginning in 2004 Honda added the GPScape model officially known as the TRX650GPS as an option which adds a built-in GPS unit contained within the instrument cluster assembly. The GPS featured storage for up to 100 waypoints, digital compass function indicating travel direction and an automatic compensating clock.

Rincon Generation 2 (2006-Current)

The Rincon continues as Hondas top-of-the line ATV but starting in 2006 Honda gave the FourTrax Rincon an update in response to customer request. The Rincon 650 became known as the Rincon 680i when the engine size enlarged from 649cc to 675cc. Officially known as the TRX680F and TRX680GPS. Along with the larger engine Electronic Programmed Fuel Injection (PGM-FI) was introduced. New colors including NaturalGear Camouflage was added, developed by a firm in Arkansas many enthusiast consider the patterns one of the most realistic available blending easily into backgrounds, particularly found in many parts of the southern United States.

This increased engine size came via a larger bore in the single-cylinder power plant, growing from 100mm to 102mm. Also, the cylinder is now of cast-sleeve design, which permits cylinder boring to an oversize of plus 0.25mm should the need ever occur. An all-new camshaft profile was utilized for increased power, a new exhaust system ensures a quiet ride, a rollover sensor now kills the engine in the event the Rincon is partially or fully overturned. The a PGM-FI system uses a 40mm throttle body replacing the carburetor used in previous Rincons. The changes resulted in an eight percent increase in torque and at a higher RPM peak, from 4500 rpm to 5000 rpm. Peak horsepower remained 6000 RPM. The overall peak power jumped approximately seven percent compared to the 2005 Rincon. A change that yielded a higher top speed than before, though electronically limited on US models to approximately 65 MPH many owners choose to have this safely feature disabled. Honda added more durable crankshaft bearings and beefed-up the transmissions gears to ensure durability and longer life while better utilizing the new engines additional power. According to Honda the PGM-FI system boasts a high-tech 12-hole split-pattern fuel injector to maximize fuel distribution to both intake valves. This is reputed to be the same injector used in Honda's popular SUV making a replacement readily available at many auto parts stores. A new high pressure fuel pump with a built-in reservoir feeds the system. Fuel injection allows the ECU to provide many benefits over previous, carbureted models that were gravity feed from the tank. The ECU can now adjust to variables and changing riding conditions in a seamless and fully automatic fashion. In addition to increased power output, some other benefits included improved fuel mileage, elimination of the manual choke and much-easier cold starting, automatic compensation at different altitudes, automatic temperature compensation, a shorter engine warm-up period, and smoother idle. An idle air control valve (IACV) establishes a basic idle setting of 1400 rpm, plus or minus 50 rpm. The automotive style automatic transmission was also updated to improve overall drivability and the torque converter was tweaked to reduce warm-up to accommodate start-and-go during extreme cold-weather riding. The manual fuel shut-off petcock was removed, with the PGM-FI an automotive style fuel gauge was added. When the fuel level reaches the E symbol a low-fuel warning light begins to flash letting the rider know that they have about 1.1 gallons of fuel remaining, or enough for approximately 28 miles of reserve range. Battery capacity was increased from 14AH to 18AH. The Rincon still has a manual recoil (rope) starter with the pull handle hidden behind a snap-off panel on the right side and incorporates an automatic internal decompression system for easier starting. Also added was a newer style reusable urethane air filter that can be washed and re-used. Mechanical features for 2006 were dual front disc brakes. Something many owners had asked for in comparison to the original Rincon's single drum brake on the front output shaft. New valving in the rear suspension makes the Rincon more even more nimble than the original. Other changes made the shock action smoother in operation than in the previous unit as well.
