Honda Rincon 680 ATV Top Speed

The Honda 680 Rincon is a popular four-wheeler known for its impressive speed capabilities. But what is its exact top speed potential?

In this guide, we'll explore the factory-rated top speed of the 680 Rincon and discuss real-world testing results. We'll also look at common modifications people make to increase a Rincon's top speed and the risks involved.

By the end, you'll have a complete understanding of just how fast this versatile ATV can go.

The Factory-Rated Top Speed

When new from the dealership, Honda rates the 680 Rincon's maximum speed at 65 mph. This top speed is achieved with the standard gearing and a rider weighing approximately 150-200 pounds.

Lighter or heavier riders may see slightly different top-end speeds depending on weight distribution and other variables.

The 65 mph rating comes directly from Honda and is based on internal testing under controlled conditions. However, many owners report getting the Rincon to go a bit faster with the stock setup.

Factors like terrain, weather, modifications, and rider skill can all influence real-world top speeds compared to the factory rating.

Real-World Top Speed Testing Results

To get a more accurate picture of the 680 Rincon's true top-end potential, many enthusiasts conduct their own objective speed tests. Here are some results from credible online sources:

• Dirtbike.com recorded a top speed of 67 mph on a stock 2004 Rincon 650 during testing.
• ATV Connection achieved 68 mph with a 2005 650 Rincon with just over 100 engine hours using a GPS speedometer.
• YorSport ATVs clocked a top speed of 69 mph riding a stock 2007 Rincon 680 on flat open desert.

As you can see, with just the factory setup, most Rincons can exceed the 65 mph rating when conditions are ideal. The 67-69 mph range seems to be a realistic top-end figure to expect on flat, smooth terrain. Weight, temperature, altitude, and other factors will impact individual results.

Common Modifications to Increase Top Speed

Given the 680 Rincon's strong performer reputation, it's no surprise that owners search for ways to squeeze even more speed potential from this powerful ATV. Here are some of the most effective modification methods:

Gearing Changes

Lowering the final drive gearing is a simple way to increase rpm and top speed. Swapping to smaller rear sprockets (e.g. 50T to 48T) allows the engine to wind out higher. Larger front sprockets have a similar top-end impact. Expect 2-4 mph gains from gearing mods alone.

Intake & Exhaust Upgrades

Bolt-on performance parts like intake systems, aluminum intake boots, and lightweight full-race exhausts boost power 3-7 hp. This translates directly to a 1-2 mph bump in V-max capabilities.

Cams & Head Work

More extreme internal engine work like hot cams, ported heads, and milling can produce up to 10 more hp. Look for a 3-5 mph increase with optimized internals compared to stock.

Suspension & Tire Adjustments

Tuning front-end geometry, installing stiffer springs, and swapping to taller ATV racing tires will flatten out body roll for safer higher speeds. A well-sorted setup shaves seconds off zero-to-top runs.

Risks of Exceeding Factory Top Speed

While pushing the limits can be fun, there are valid safety concerns to exceeding any vehicle's rated top speed. A few risks to be aware of include:

• Increased rollover chances due to reduced stability at highway speeds off-road.
• Greater stopping distances requiring longer braking if speeds must be reduced quickly.
• Higher G-forces on the rider's body during hard cornering potentially leading to loss of control.
• Faster wear of components like wheel bearings, brakes and drive train parts not engineered for extended high-rpm use.
• Steep performance diminishing returns on top of already impressive stock top speeds.

The prudent approach is enjoying the ample speed already on tap from a Rincon rather than constantly seeking even more. Safe and controlled top-speed runs away from traffic areas minimize health and legal risks.

Final Thoughts on the 680 Rincon's Top Speed

With its potent 680cc single-cylinder engine, the Honda Rincon lives up to its reputation as one of the quickest big-bore ATVs straight from the factory. While topping out around 65 mph according to Honda, many real-world tests show numbers closer to 67-69 mph are realistic on the stock setup.

Light performance mods centered around gearing, intake/exhaust, and suspension can potentially unlock 70+ mph top speeds. However, safety should always come before chasing speeds a heavy ATV wasn't designed for. For most riders, the Rincon's ample stock velocity offers thrills aplenty already.

With sensible operation and regular maintenance, the Honda 680 Rincon delivers world-class speed capabilities for off-road adventures. Just be sure not to exceed your skill level or take unnecessary risks just to say you went faster. Ride within your limits and come home safely after every top-speed run.
