Polaris 700 ATV: Power & Performance

When considering an ATV for serious off-road adventures, the Polaris 700 engine often comes up in conversation. Known for its robust performance and reliability, Polaris has a long-standing reputation for producing powerful and capable all-terrain vehicles. The question of 'How much horsepower does a Polaris 700 have?' is a common one, and the answer can vary slightly depending on the specific model and year. However, understanding the lineage and development of Polaris engines provides valuable context.

The Evolution of Polaris Sportsman Engines

The Polaris Sportsman line has a rich history, with its debut dating back to 1996 with the Sportsman 500. This pioneering model featured independent front and rear suspension and a single-cylinder engine that delivered a respectable 35 horsepower. This set the stage for Polaris' commitment to innovation and performance.

A significant leap occurred in 2003 with the introduction of the Sportsman 700 EFI. This model marked Polaris' entry into the twin-cylinder market for ATVs. Equipped with a 700cc twin-cylinder engine featuring electronic fuel injection (EFI), it pumped out approximately 45 horsepower. This was a substantial increase from its predecessor and offered riders a noticeable boost in power for tackling more demanding trails.

Following the success of the 700, Polaris continued to push the boundaries of ATV performance. The ProStar engine line emerged, with the ProStar 850 delivering a potent 78 horsepower. The evolution continued with the introduction of the 1000cc models, such as the Sportsman XP 1000 Premium Trail Package, which boasts a staggering 90 horsepower from its 952cc twin-cylinder ProStar engine.

Focus on the Polaris 700 Engine

While the newer, larger displacement engines are impressive, the Polaris 700cc engine holds a special place for many ATV enthusiasts. The 2003 Sportsman 700 EFI, with its 45 horsepower, provided a significant upgrade in performance, making it a capable machine for various off-road activities.

For those looking at specific years, like the 2006 Polaris 700, it's important to note that these engines, often referred to as the 755cc engine due to their actual displacement, are generally considered good running engines, provided they have received all necessary updates. Information available from owner forums, particularly those dedicated to Polaris snowmobiles (as engine technology often crosses over), suggests that these engines benefit greatly from proper maintenance and adherence to manufacturer recommendations.

Key Considerations for 700cc Engines:

• Engine Warm-up: These engines, much like some diesel engines, perform optimally when properly warmed up. A minimum of 80°F (27°C) is recommended, with 100°F (38°C) being ideal for safe and efficient operation. They are described as 'cold-blooded,' meaning they require ambient heat to reach their peak performance and longevity.
• Intake Boots: A common point of attention for these engines is the intake boots. Cracks or dryness in these components can lead to lean conditions, affecting performance and potentially causing damage. Regular inspection, ideally twice a season, is crucial to ensure they are in good condition and not compromised.
• Updates and Maintenance: Staying current with any manufacturer updates or recalls is vital for the longevity and performance of the 700cc engine. Cross-referencing information with larger engine platforms, such as the 900cc or 866cc engines, can also provide insights into potential issues and solutions.

Performance and Features of a Polaris Sportsman XP 1000 (for context)

To provide a benchmark and highlight Polaris' advancements, let's look at the Sportsman XP 1000 Premium Trail Package. This model, while significantly more powerful than the 700, showcases the engineering prowess of Polaris:

The XP 1000's 90 horsepower engine offers exhilarating acceleration and the ability to tackle challenging terrain with ease. Features like the redesigned seat for enhanced comfort, improved LED lighting for visibility, and A-arms with double arches for increased ground clearance demonstrate Polaris' continuous efforts to enhance the rider experience.

Riding Experience and Handling

The Polaris 700, and its successors, are designed with rider comfort and capability in mind. While the 700cc engine provides ample power for most trail riding, understanding its handling characteristics is important. The smooth suspension on models like the Sportsman is excellent for absorbing standard trail bumps, contributing to a comfortable ride over long distances.

For riders who prefer a more aggressive style or tackle very rough terrain, adjustments to the shock absorbers' compression clickers might be beneficial. Some riders have noted that with the vehicle's weight and the suspension's inherent smoothness, a front sway bar can be a worthwhile addition for those pushing the limits in fast cornering.

Areas for Improvement (as noted in related models)

Even with well-regarded engines, manufacturers often identify areas for refinement. In the context of Polaris ATVs, some common points of discussion, even for more recent models, include:

• Speedometer Design: Some riders have expressed a desire for a revised speedometer design for better clarity and functionality.
• Power Steering at High Speeds: While power steering is a welcome feature, especially at low speeds, some users have found that its assistance remains too high at elevated speeds. A more progressive power-assisted steering system would be a desirable enhancement for those who frequently ride at higher velocities.
• Suspension Stability: The plushness of the suspension, while comfortable, can sometimes lead to a slight reduction in stability at higher speeds, especially when combined with full-power steering assistance. Vigilance and awareness of the machine's limits are key for riders who push the performance envelope.

These points highlight that while Polaris engines, including the 700cc variants, offer strong performance, the overall machine refinement is an ongoing process. The immense power available from these engines means that a rider's skill and the machine's handling characteristics must be well-matched.
