Yamaha Rhino 660: Specs, Features, Towing & Used Buying Guide

The Yamaha Rhino 660 is a two-seat side-by-side that helped define the early sport-utility UTV category. Introduced in North America in 2003, it combined a 660cc liquid-cooled single-cylinder engine, automatic CVT, selectable 2WD/4WD, independent suspension, a 400-lb cargo bed, and up to 1,212 lbs of towing capacity. It is no longer produced, so buyers today are mainly shopping the used market. The Rhino 660 still makes sense for light property work, hunting, and recreational trails, but its age means condition, maintenance history, and replacement-part availability matter as much as the original specifications.

Why the Yamaha Rhino 660 Mattered

In the early 2000s, ATVs were already popular for outdoor recreation, farming, and property work. But they had obvious limitations: limited passenger space, little cargo capacity, and less protection for riders.

The Yamaha Rhino 660 helped bridge the gap between a traditional ATV and the modern side-by-side.

Yamaha introduced the 660cc Rhino in North America in 2003. It combined ATV-like trail capability with:

• Side-by-side seating
• Steering wheel controls
• Roll-cage structure
• Cargo bed
• Automatic transmission
• Selectable four-wheel drive

That combination helped establish the sport-utility side-by-side format that later became a major part of the UTV market.

Yamaha later replaced the 660cc version with the larger Rhino 700 platform, so the Rhino 660 should now be viewed as a historical used UTV rather than a current Yamaha model.

Yamaha Rhino 660 Specs at a Glance

Exact dimensions and weight can vary slightly by model year and configuration, so owners should use the service or Owner’s Manual for their specific Rhino 660 when confirming maintenance, tire pressure, towing, or replacement-part specifications.

Yamaha Rhino 660 Features

1. 660cc Single-Cylinder Engine

The Rhino 660 uses a liquid-cooled 660cc four-stroke single-cylinder engine.

Its purpose was never to compete with modern high-horsepower sport UTVs. Instead, the engine delivered useful low- and mid-range power for:

• Property roads
• Hunting trails
• Steep terrain
• Light hauling
• Recreational riding

For a machine from this generation, the engine and driveline were designed around usable utility performance rather than outright speed.

Because every Rhino 660 is now an older used vehicle, engine condition matters more than the original performance numbers. Compression, oil consumption, cooling-system condition, carburetor tuning, and previous maintenance should all be checked before purchase.

2. Automatic CVT and Selectable 4WD

One of the Rhino 660’s strongest practical features is its automatic V-belt transmission.

Drivers do not need to operate a manual clutch, making the vehicle easier to use around property, trails, and work areas.

The drivetrain also provides selectable 2WD and 4WD with differential-lock capability.

That gives the driver flexibility:

• Use 2WD on easier terrain
• Engage 4WD when traction decreases
• Use differential lock when additional traction is needed

On an older Rhino, check that the 4WD and differential-lock functions engage correctly before buying.

3. Two-Seat Cabin

The Rhino 660 uses side-by-side seating for a driver and one passenger.

Compared with an ATV, this provides a more automotive-style experience with:

• Steering wheel
• Bucket-style seating
• Seat belts
• Passenger grab handle
• Protective cage structure

The cabin is compact compared with many modern UTVs, which can be useful on narrower trails and in smaller storage spaces.

However, owners should remember that the Rhino 660 was engineered to safety standards and design expectations from more than two decades ago. Always keep factory restraint systems in good condition and follow the Owner’s Manual.

4. Cargo and Towing Capability

Utility was a major part of the Rhino 660’s appeal.

Yamaha specifies a maximum cargo-bed load of 400 lbs and a maximum rolling towing weight of 1,212 lbs, with a maximum tongue weight of 110 lbs.

That makes the Rhino useful for:

• Carrying tools
• Moving hunting gear
• Transporting small loads around property
• Pulling a light utility trailer

These numbers should not be treated as targets to exceed.

When towing, Yamaha instructs operators to use low range, allow for increased braking distance, and use extra caution on inclines.

5. Independent Suspension

The Rhino 660 uses independent suspension at both the front and rear.

That helped distinguish it from simpler utility vehicles of its era and contributed to its ability to handle uneven trails while still carrying cargo.

Independent suspension allows each wheel to move more independently over:

• Rocks
• Ruts
• Washouts
• Uneven property roads

Today, suspension condition should be inspected closely on any used Rhino 660.

Check:

• Bushings
• Ball joints
• Wheel bearings
• Shock leakage
• CV boots
• Control-arm damage

Age and wear can change how the machine handles much more than the original suspension specification suggests.

6. Compact Trail-Friendly Design

One reason owners still keep older Rhino models running is their relatively compact footprint.

The Rhino 660 is much smaller than many modern four-seat and high-performance side-by-sides.

That can make it useful for:

• Wooded property
• Hunting trails
• Barn access
• Tight storage areas
• Moderate recreational riding

Compact dimensions can also make trailering easier.

However, exact width and overall dimensions changed slightly by model year, so measure the actual vehicle if trailer or garage clearance is tight.

What Is the Yamaha Rhino 660 Best Used For?

The Rhino 660 works best when expectations match what the machine was originally designed to do.

Property and Light Work

The cargo bed and towing capability make it useful for:

• Fence inspection
• Moving tools
• Yard work
• Small farms
• Light hauling

For heavy towing or large payloads, modern full-size utility UTVs offer significantly more capacity.

Hunting

The compact chassis, four-wheel-drive system, cargo bed, and relatively simple drivetrain make the Rhino 660 a practical older hunting machine.

Useful upgrades can include:

• Windshield
• Rear windshield
• Roof
• Storage
• Mirrors
• Secure equipment mounts

Recreational Trails

The Rhino 660 can still be enjoyable on moderate trails, particularly for riders who prefer a smaller, simpler machine.

It is not directly comparable with modern sport UTVs in power, suspension travel, or high-speed capability.

Is the Yamaha Rhino 660 Still Worth Buying?

It can be, but the answer depends heavily on condition and price.

A Rhino 660 may still make sense if you want:

• A compact two-seat side-by-side
• Basic property utility
• Hunting transportation
• Moderate trail capability
• A relatively simple older platform

It makes less sense if you need:

• Modern high-output performance
• Heavy towing
• Large payloads
• Four or more seats
• Current factory technology
• New-vehicle warranty coverage

The machine’s age is the biggest consideration.

At this point, a well-maintained Rhino 660 with documented service history is usually more attractive than one with more accessories but unknown mechanical condition.

Conclusion

The Yamaha Rhino 660 remains an important early sport-utility side-by-side because it combined trail capability with practical work features in a compact two-seat platform.

Its 660cc engine, automatic CVT, selectable 4WD, independent suspension, 400-lb cargo bed, and 1,212-lb towing capacity made it useful for property work, hunting, and recreational riding.

Today, however, the buying decision is less about its original specifications and more about condition.

At StarknightMT, we recommend checking the engine, CVT, 4WD system, suspension, brakes, frame, and maintenance history before investing in accessories or restoring an older Rhino.

If the machine is mechanically sound and your needs are moderate, the Rhino 660 can still be a practical and enjoyable side-by-side more than two decades after its introduction.
