Finding a capable big-bore utility quad on a budget often leads buyers straight to the mid-2000s market. The 2006 Polaris Sportsman 700 delivers massive twin-cylinder power and a famously plush independent rear suspension for a fraction of the cost of a new machine. If you're shopping for a used utility quad that punches well above its price tag, this model demands a close look. However, two decades of wear mean you'll need to separate well-maintained workhorses from neglected money pits.
Navigating the used market for this specific machine requires understanding its real-world mechanical quirks, exact factory specifications, and common failure points. While the carburetor and electronic fuel injection variants offer rugged capability, they also carry specific maintenance realities that sellers rarely advertise. Let's break down what you actually need to know before handing over cash.
Core Specifications and Performance
Polaris built the 2006 lineup around a 683cc liquid-cooled, four-stroke twin-cylinder engine. Buyers during this era could choose between a traditional carburetor setup or the updated Electronic Fuel Injection system. The EFI versions generally command a higher used price because they eliminate cold-weather starting headaches and adjust automatically to elevation changes.
The machine puts power down through a Continuously Variable Transmission featuring high, low, neutral, reverse, and park. Power delivery is immediate, offering plenty of low-end grunt for crawling over rocks or pulling heavy loads.
- Engine Type: Liquid-cooled 4-stroke twin cylinder
- Displacement: 683 cc
- Dry Weight: Approximately 756 to 770 lbs depending on configuration
- Towing Capacity: 1,200 to 1,500 lbs
- Front Suspension: MacPherson strut with 8.2 inches of travel
- Rear Suspension: Progressive rate independent double A-arm with anti-roll bar
The standout feature of this chassis remains its ride quality. The independent rear suspension absorbs ruts, roots, and choppy trails far better than rigid-axle competitors from the same era, making long days in the saddle much less fatiguing on your back.
Common Mechanical Issues to Inspect
Every used ATV has weak spots, and the Sportsman 700 is no exception. Inspecting these specific areas during a pre-purchase walkthrough can save you hundreds of dollars in unexpected garage bills.
Cooling System and Water Pump Integrity
Factory water pump housings on many mid-2000s Polaris models used composite materials that were prone to warping under high heat cycles. When the housing warps, coolant leaks past the seal. Because the temperature sensor location doesn't always trigger an immediate warning if coolant levels drop critically low, overheating can quickly lead to warped heads or blown head gaskets. Check the weep hole underneath the engine block for any crusty residue or active leaks.
Electrical Harness and Charging Gremlins
Older Polaris quads are sensitive to battery voltage drops and moisture intrusion in the wiring harness. Look under the front pod and around the battery tray for corroded terminals, spliced wires, or exposed copper. If the instrument cluster flickers or the machine struggles to maintain a charge while running, you're likely looking at a failing stator or a tired voltage regulator rectifier.
CVT Belt and Clutch Wear
The Polaris PVT system relies on a rubber drive belt that wears down over thousands of miles. Pop the CVT cover off if the seller allows it, or test-drive the machine to check for smooth engagement. If the quad jerks violently or hesitates when you touch the throttle, flat spots on the clutch weights or a grooved clutch sheaves need replacement.
Used Pricing and Market Value
Pricing for a 2006 Polaris Sportsman 700 varies heavily based on mechanical condition, cosmetic wear, and regional demand. Because these machines double as utility vehicles and recreational trail quads, hours of operation matter far more than the model year alone.
- Project Condition: Under $1,500. Usually requires electrical work, new tires, or top-end rebuilds. Best left for experienced DIY mechanics.
- Fair Rider Condition: $1,800 to $2,800. Starts reliably, shifts into gear, and runs through all ranges, but shows cosmetic scratches, torn seat vinyl, or worn suspension bushings.
- Collector or Immaculate Condition: $3,000 to $4,200. Garage-kept, low miles, clean plastics, and a documented maintenance history with upgraded aftermarket bushings or sealed water pumps.
Before buying, verify registration laws in your state or province. Many jurisdictions require off-highway vehicle decals or titles, and missing paperwork can complicate your purchase. You can check official regulatory requirements through resources like the California Department of Parks and Recreation or equivalent local agencies to ensure the machine transfers cleanly.
Maintenance Checklist for Long-Term Reliability
Keeping a big-bore utility ATV running for another decade requires proactive upkeep. Skipping routine service intervals is the primary reason these engines fail prematurely.
- Change Engine Oil Regularly: Use factory-spec 0W-40 synthetic oil every 50 hours or once per riding season to protect the twin-cylinder internals.
- Grease Suspension Zerks: The A-arm bushings feature grease fittings that need fresh marine grease periodically to prevent premature slop and squeaks.
- Inspect the Air Box: Ensure the air filter seal is tight. Dust ingestion is a fast track to scored cylinder walls in dusty trail conditions.
- Monitor Gearcase Fluids: Change front demand drive fluid and rear gearcase oil annually to protect the all-wheel-drive engagement mechanism.
For additional technical diagrams, part numbers, and official service intervals, consult the resources provided by Polaris Industries. Having the factory service manual on hand makes troubleshooting electrical and mechanical issues significantly easier.
Frequently Asked Questions
Does the 2006 Polaris Sportsman 700 have power steering?
No. Electric power steering was not offered on this model year. Steering effort is manageable at speed, but low-speed maneuvering in heavy mud or tight technical turns requires some upper body strength.
Can this ATV be pull-started if the battery dies?
Unlike smaller displacement models like the Sportsman 500, the high compression ratio of the 700 twin-cylinder engine means it does not feature an emergency manual pull-starter. If the battery is completely dead, you must jump-start it or replace the battery.
What kind of fuel does it require?
The machine runs fine on standard 87-octane pump gasoline. However, if you store the quad for winter, use a quality fuel stabilizer to prevent varnish from clogging the carburetor jets or fuel injectors.
How does the all-wheel-drive system work?
Polaris uses an On-Demand true all-wheel-drive system. When the rear wheels slip, the front hub system engages automatically, returning to two-wheel drive once traction is restored without requiring manual differential levers.
