Performance:

• The 1987 Yamaha Banshee was designed for sport and recreational riding, and its two-stroke, twin-cylinder engine was one of the standout features. The engine produced roughly 30-35 horsepower, which made it an exhilarating ride with great acceleration and top-end speed.
• The 6-speed transmission provided the rider with precise control over the power delivery, while the manual clutch offered a more engaging riding experience, especially for enthusiasts who enjoyed racing or aggressive trail riding.

Handling:

• The Banshee’s independent front suspension and rear monoshock suspension offered good handling for its time, although it wouldn’t match modern suspension technology. However, the relatively light weight of the Banshee (around 370 lbs) combined with its low seat height made it very nimble and easy to control in various terrains, from dunes to trails.

Notable Features:

• 2-Stroke Power: The 1987 Banshee was a two-stroke ATV, which means it had a high-revving engine that provided a unique sound and instant throttle response, making it extremely popular with racing and performance enthusiasts.
• Distinctive Styling: The original design featured bold bodywork in Yamaha’s signature blue and white colors. While the body style remained somewhat similar throughout the years, the 1987 model stands out as the beginning of the Banshee legacy.

Modifications:

As with many other high-performance vehicles, the 1987 Banshee is a popular platform for modifications. Common upgrades include:

• Exhaust Systems: Aftermarket expansion chambers and exhaust pipes are often installed to improve exhaust flow and boost horsepower.
• Carburetors: Upgrading to larger carburetors (34mm or 36mm) or installing reed valves can increase fuel flow and improve throttle response.
• Suspension: Upgraded shocks and suspension components, such as those from Elka or Works, are often added for better handling and ride quality.
• Engine Kits: Big bore kits and high-compression pistons can increase the engine’s displacement to 350cc or more, resulting in a significant boost in power.

Legacy and Popularity:

The 1987 Yamaha Banshee became an icon in the ATV world due to its combination of powerful performance, reliable design, and unique sound. It remained in production for nearly two decades (until 2006) and developed a loyal following, especially in racing, dunes, and aggressive trail riding.

Although Yamaha discontinued the Banshee in 2006 due to stricter emissions regulations for two-stroke engines, the 1987 model remains one of the most sought-after and beloved by enthusiasts. The Banshee’s popularity has also led to a thriving aftermarket parts and restoration market, which helps owners keep their machines in top shape.

Maintenance:

Given the age of the 1987 Banshee, regular maintenance is key to keeping it running smoothly:

• 2-Stroke Oil: Regularly mix high-quality 2-stroke oil with gasoline if the Autolube system is not used.
• Carburetor Tuning: Keep the carburetors clean and properly tuned to ensure proper fuel delivery and performance.
• Exhaust Maintenance: Check and clean the exhaust system to prevent carbon buildup and ensure the engine breathes efficiently.
• Suspension Care: Inspect and replace suspension components as necessary to maintain handling and ride quality.
• Clutch Maintenance: Since the 1987 Banshee uses a manual 6-speed transmission, keeping the clutch in good working condition is essential for smooth shifting and control.

Value:

As a collector’s item and a performance machine, the 1987 Yamaha Banshee has strong value, particularly if it’s in good condition or has been well-restored. Modified versions with racing or performance parts tend to fetch a higher price due to their enhanced power and handling.
