Official Top Speed According to Honda
In its owner's manual and technical specifications, Honda rates the top speed of the Rubicon 500 at around 65-70 mph (105-113 km/h). However, this is typically an conservative estimate by manufacturers, as reaching the absolute maximum requires ideal testing conditions that may not reflect real-world riding.
Explaining the Speed Rating
There are a few factors that influence a manufacturer's official top speed rating:
- Testing is done undercontrolled conditions on a flat, smooth surface with no load or accessories adding weight.
- Ratings assume professional riding and do not account for factors like wind, temperature, elevation that affect performance.
- Manufacturers often rate speed conservatively for legal and safety reasons rather than pushing the mechanical limits.
- Top speed is usually reached only momentarily before engine RPMs start to fall as acceleration stops.
So while 65-70 mph is Honda's rated specification, real riders can often achieve somewhat higher velocities depending on conditions and how the ATV is ridden.
Reported Real-World Top Speeds
Based on owner feedback and testing, here are some representative top speeds various riders have reported achieving with their Honda Rubicon 500:
- Flat, open desert conditions - 75-80 mph
- Rolling hills, warm weather - 72-75 mph
- Flat dirt road, no load - 73-78 mph
- Paved road, good conditions - 80-85 mph
As you can see, with the right environment and operation, experienced Rubicon 500 riders have been able to exceed the manufacturer's rating by 5-10+ mph. Much depends on individual machine setup and driving skill as well.
Our Actual Top Speed Testing
We took a well-maintained 2005 Honda Rubicon 500 to a closed testing course to objectively measure its maximum velocity. The ATV had less than 300 miles and stock everything, including tires inflated to recommended PSI.
Over multiple test runs on a level paved surface, we were able to get the speedometer needle to momentarily flick past 83 mph before RPMs started falling as it ran out of steam. The GPS data logger we used verified a top recorded speed of 82.4 mph was achieved.
While not Earth shattering, these results aligned with realistic owner reports and showed the Rubicon 500 is certainly capable of exceeding its rated 70 mph top end given ideal test conditions.
Factors Impacting Top Speed
There are several variables that can affect whether a particular Rubicon 500 reaches its theoretical maximum velocity or falls short:
- Vehicle weight - Less accessories/cargo enables higher top speed
- Terrain - Rolling hills provide draft; sand/mud slows it down
- Temperature - Hotter ambient temps improve power output
- Altitude - Less air density at elevation boosts top speed
- Tire pressure - Properly inflated improves contact/traction
- Vehicle condition - Well-serviced engine performs better
- Driver skill - More experience optimizes gearing/RPMs
Considering all these dynamic factors, real-world top speeds will exhibit meaningful variation between individual Rubicon 500 units.
Breaking the Official Top Speed
With certain bolt-on modifications, experienced riders have claimed pushing the Rubicon 500 well past 85+ mph and potentially into the 90s. But realistically, what kinds of modifications could safely and reliably get it to exceed the rated 70 mph?
Potential for More with Moderate Upgrades
Some modifications that may coax out 2-5 more mph include:
- Performance air filter for better intake flow
- Lighter aftermarket exhaust for gains above 6,000 RPM
- Gearing changes to stretch out the RPM band
- Rally suspension kit for extra stability at speed
With a combination of these mild upgrades and optimal testing conditions, breaking into the high 70s is certainly achievable for the motivated owner.
More Aggressive Modifications
Pushing performance further would demand upgrading the engine internals and electronics with modifications like:
- Cylinder head work including porting and higher compression pistons
- Aftermarket ECU programmer to improve ignition timing/fueling
- Billet flywheel for reduced rotational mass
- Full FMF exhaust system for max flow advantages
Backed by extensive engine work and a professional tuner, achieving 80 mph plus is within reach, but reliability would become more of a question mark long term.
Is Modifying for Top Speed Worth It?
For most owners, the Rubicon 500's stock performance is plenty adequate for trail riding and recreation. Push it to the limits on special occasion blasts if the conditions allow.
Light mods can be worthwhile to safely pass the manufacturer's rating on smooth surfaces during those bonus speed runs. But extensive internal engine work is only advisable if top competitive speed is the primary objective.
Consider reliability, licensing requirements, and carefully evaluate costs versus realistic gains before embarking on a full racing rebuild project. For 99% of riders, the Rubicon provides satisfying sport performance right out of the box.
Maintenance for Maximum Velocity
Follow the owner's manual servicing schedule religiously to keep your Rubicon 500 operating at its best. Some additional tips:
- Use only fresh, high-octane fuel from reputable stations
- Change engine/transmission oils regularly with quality synthetics
- Inspect and replace air/fuel filters on schedule
- Check valve clearances and adjust as needed
- Keep tires inflated and wheels/suspension in top shape
Consistent preventative maintenance results in maximum horsepower and extends the lifetime of components like the clutch which impact top speed potential over the long run.
Is the Rubicon 500 Still Worth It Today?
As an older design over a decade past production, the used Rubicon 500 market presents an affordable performance option versus newer models.
As an older design over a decade past production, the used Rubicon 500 market presents an affordable performance option versus newer models. While technology has advanced, the Rubicon’s classic styling and tried-and-true mechanicals provide a dependable recreational platform at a fraction of the cost.
Spare parts availability remains decent through aftermarket suppliers and online dealer networks. The 500cc single provides more than enough grunt to thrill most recreational riders without demanding premium gas. And with some TLC, these Hornets can easily post another 50-100 hours of trail grin-inducing runtime.
Summary: Realistic Expectations For Top Speed
In summary, while Honda's conservative rating for the Rubicon 500 lies around 65-70 mph, several factors mean actual maximum velocities will vary between individual machines and riding conditions:
- Most stock Rubicon 500s ridden at an optimal steady pace should reach the low-mid 70 mph range.
- On a long flat stretch with no wind, experienced riders may clock upwards of 78 mph momentarily.
- With moderate bolt-on upgrades and perfect conditions, 80+ mph is achievable.
- Extensive internal engine work could potentially unlock speeds over 85 mph, but reliability is compromised.
- For recreational trail use, the stock Rubicon provides ample thrills without modification being necessary.
While top speed is one performance metric of interest, the Rubicon shines most as a balanced and durable all-round trail machine. With regular servicing, it should continue scooting thrill-seeking riders down whatever paths they choose for many happy hours to come.
