1987 Suzuki LT500 QuadZilla – The Original Two-Stroke ATV Legend
The 1987 Suzuki LT500 QuadZilla is one of the most iconic and groundbreaking ATVs ever produced. As the first high-performance two-stroke sport quad over 500cc, the LT500 forever changed the off-road world. Known for its massive power, aggressive design, and advanced engineering for its time, the 1987 QuadZilla earned legendary status and remains one of the most sought-after classic sport ATVs today.
At the heart of the 1987 Suzuki LT500 QuadZilla is a massive 498cc liquid-cooled, two-stroke single-cylinder engine. This engine was revolutionary in the ATV market, delivering incredible torque, blistering acceleration, and a top-end rush that shocked riders in the late 1980s. Producing power levels that rivaled small motorcycles, the QuadZilla earned its fearsome nickname through sheer performance alone. The two-stroke design allowed for a high power-to-weight ratio, making the LT500 one of the fastest ATVs of its era.
Fueling the engine is a large carburetor paired with Suzuki’s Automatic Exhaust Control (AEC) system, which helps broaden the powerband by improving low-end and midrange response. Power is sent through a 5-speed manual transmission with a manual clutch, giving riders full control over the engine’s aggressive output. This setup made the QuadZilla a true rider’s machine, best suited for experienced enthusiasts who could handle its raw power.
The chassis of the 1987 LT500 QuadZilla features a strong tubular steel frame designed to handle the engine’s immense output. While heavier than smaller sport ATVs, the QuadZilla’s frame provides stability at high speeds and during hard acceleration. Its wide stance and long wheelbase contribute to straight-line stability, making it especially effective in open terrain and sand dunes.
Suspension on the 1987 Suzuki LT500 consists of dual A-arm front suspension and a rear swingarm with a single shock. For its time, this suspension setup was considered advanced and capable of handling aggressive riding. While modern suspension technology has surpassed it, the QuadZilla’s suspension remains functional and is highly upgradeable, with many aftermarket options available for riders seeking improved handling and comfort.
Stopping power is delivered through hydraulic disc brakes, providing reliable braking performance for such a powerful machine. Combined with its stable chassis and predictable handling, the QuadZilla offers confidence-inspiring control when ridden within its limits.
One of the most distinctive features of the 1987 Suzuki LT500 QuadZilla is its bold and aggressive design. The oversized engine, wide bodywork, and muscular stance give it an unmistakable presence. The LT500 looks as powerful as it performs, and its unique styling has become iconic among vintage ATV enthusiasts. Its large expansion chamber exhaust system further emphasizes its performance-focused nature.
The QuadZilla also benefits from strong aftermarket and enthusiast support, even decades after production ended. Owners can still find performance upgrades, replacement parts, and restoration components, making the LT500 a popular choice for collectors and builders. Many riders customize their QuadZillas with upgraded suspension, exhaust systems, carburetors, and modern braking components to enhance performance while preserving its classic character.
The 1987 Suzuki LT500 QuadZilla represents a brief but unforgettable era in ATV history. Produced only from 1987 to 1990, the LT500 was eventually discontinued due to rising emissions regulations and safety concerns. As a result, surviving examples have become increasingly rare and valuable, especially those in original or well-restored condition.
Whether you’re a collector seeking a milestone machine, a two-stroke enthusiast chasing unmatched torque, or a vintage ATV fan looking for a true legend, the 1987 Suzuki LT500 QuadZilla delivers raw power, historic significance, and timeless appeal. It remains one of the most extreme and influential sport ATVs ever built—and a true icon of off-road performance.
