What Problems Does the 2019 Polaris 800 Switchback&174 PRO-S 137 Have?

While the 2019 Polaris 800 Switchback® PRO-S 137 is generally considered a robust machine, like any complex mechanical product, it has had some reported issues and areas to monitor for long-term reliability. One commonly discussed area across Polaris 800 Cleanfire® engines, including those in the 2019 models, can be clutch performance and belt durability. Owners sometimes report premature belt wear or slippage, especially under aggressive riding conditions or if the clutching is not properly set up for the specific rider's needs. Ensuring the clutches are clean, aligned, and that the correct belt is used is crucial. Some users have also noted the potential for heat management issues in extreme conditions, which can be mitigated by ensuring proper airflow and checking for any obstructions in the cooling system. Regarding recalls, it's essential to check the official Polaris website or NHTSA database for any specific campaigns related to the 2019 model year. For instance, there may have been recalls related to specific component failures or safety enhancements. Owners should always ensure their machine is up-to-date with any issued recalls. In terms of long-term reliability, the 800cc engine is known for its power, but like most high-performance two-stroke engines, it demands diligent maintenance. Regular oil changes, spark plug replacements, and proper storage during the off-season are paramount. Some owners have reported concerns with the fuel pump, though this is not exclusive to the 2019 model year. Overall, with consistent and thorough maintenance, the 2019 Polaris 800 Switchback® PRO-S 137 can offer many years of enjoyable riding. Proactive inspection of suspension components, especially the shocks and bushings, is also recommended as wear and tear can affect handling and comfort over time.

How long will the 2019 Polaris 800 Switchback&174 PRO-S 137 last?

Estimating average mileage for a 2019 Polaris 800 Switchback® PRO-S 137 is challenging without extensive owner data, but typically, well-maintained snowmobiles can accumulate 5,000 to 10,000 miles or more over their lifespan. For those who ride extensively, reaching 8,000-12,000 miles is certainly achievable within 5-10 years. Long-term durability is heavily influenced by maintenance habits. Regular servicing of the engine, clutch, and suspension is critical. Weaknesses that might emerge over time include wear on the track, potential issues with the drive system, and suspension component fatigue. However, the core engine and chassis are generally robust. Owners who perform pre-ride inspections, post-ride cleanings, and adhere to the recommended maintenance schedule will find this snowmobile to be a durable companion.

What Technology & Safety Features are Included?

The 2019 Polaris 800 Switchback® PRO-S 137 focuses primarily on performance and rider control rather than extensive infotainment or driver-assistance systems, as is typical for snowmobiles.

Built-in Tech: The primary technological feature is the digital gauge cluster. This display provides essential information such as speedometer, tachometer (RPM), fuel level, coolant temperature, and diagnostic codes. Some models might include features like a clock and trip odometer.

Entertainment: Dedicated entertainment systems like audio units or advanced navigation are generally not standard on this model. Riders seeking music would typically install aftermarket systems.

Driver-Assistance Features: Snowmobiles do not have traditional driver-assistance systems like those found in cars (e.g., adaptive cruise control, lane keeping assist). The rider is entirely in control. However, features like the PRO-RIDE® front suspension and the PRO-XC™ rear suspension contribute to a more controlled and less fatiguing ride, indirectly assisting the driver by improving handling and absorbing impacts.

Safety Features: Standard safety features include powerful hydraulic disc brakes for reliable stopping, a bright headlight system (often halogen with LED accents) for visibility, and a kill switch tether that can shut off the engine if the rider is ejected. The design of the chassis and suspension also contributes to overall stability and control.

Optional Features: While not standard, Polaris offers a range of optional accessories that can enhance the snowmobile. These might include:
  • Heated grips and thumb warmer controls (often standard but sometimes upgraded)
  • Mirrors
  • Windshields of varying heights for better wind protection
  • Storage solutions (e.g., tunnel bags, rack bags)
  • Aftermarket audio systems
  • Handguards for added protection from wind and debris
  • Powder coated skis or upgraded track for specific conditions
Crash-Test Ratings: Snowmobiles are not subjected to crash-test ratings in the same way as automobiles. Safety is primarily determined by the machine's design, handling characteristics, and the rider's skill and adherence to safety practices. Polaris designs its vehicles with rider safety and stability in mind, but it's up to the operator to ride responsibly and within their capabilities.

Reliability: Historically, Polaris has had some reliability concerns, particularly with certain engine components or clutches, though the 800cc Cleanfire® engine is generally robust when properly maintained. Ski-Doo's E-TEC engines have a strong reputation for reliability and efficiency. Arctic Cat's reliability can be more variable depending on the specific engine and model year.

Price: The 2019 Polaris 800 Switchback® PRO-S 137 was competitively priced against its rivals when new. Currently, used prices are also fairly comparable across brands for models of similar age and condition.

Recommendations:
  • Similar Alternatives: Ski-Doo Renegade Backcountry X, Arctic Cat M8000 Mountain Cat (though often more trail-biased than a pure mountain sled, it offers crossover capability). These offer comparable performance and features within the crossover segment.
  • Potentially Better Alternatives (depending on priorities): If ultimate on-trail comfort and refinement are paramount, a Ski-Doo Renegade with its advanced suspension might be preferred. If a more pure off-trail experience is desired, a dedicated mountain sled from any manufacturer might be considered, though at the expense of on-trail manners. For those prioritizing fuel efficiency, a Ski-Doo E-TEC model could be a strong contender.
Ultimately, the best choice depends on individual riding preferences and the specific conditions encountered.

Final Verdict: Is the 2019 Polaris 800 Switchback&174 PRO-S 137 a Good Vehicle?

The 2019 Polaris 800 Switchback® PRO-S 137 is ideal for adventurous riders seeking a versatile crossover snowmobile that excels on groomed trails but can also venture off into ungroomed or lightly powdered snow. It's a great choice for those who enjoy spirited riding and appreciate responsive handling.

This snowmobile is definitely worth buying, especially on the used market where it offers considerable value. Its combination of a powerful 800cc engine and premium PRO-S suspension makes it a capable performer.

Buying used is highly recommended, given its age and the depreciation already experienced. Look for models with a strong maintenance history, relatively low mileage, and in good mechanical and cosmetic condition. While new models are rare, if found, they would carry a premium price. The PRO-S trim is particularly attractive for its enhanced suspension, making it a superior choice for performance-oriented riders over base models.
