2006 Suzuki LTR450R – Championship-Bred Four-Stroke Sport ATV
The 2006 Suzuki LTR450R marked a turning point in the sport ATV world, introducing a machine designed from the ground up to compete and win at the highest levels of racing. Developed with direct input from Suzuki’s factory racing program, the LTR450R quickly earned a reputation for its advanced engineering, powerful four-stroke performance, and race-ready handling. As Suzuki’s flagship sport quad, the 2006 LTR450R remains one of the most respected high-performance ATVs ever built.
At the core of the 2006 Suzuki LTR450R is a 450cc liquid-cooled, four-stroke single-cylinder engine with dual overhead cams (DOHC) and four valves. This engine delivers strong, smooth power across a wide RPM range, offering excellent low-end torque, responsive midrange pull, and a strong top end. Unlike older two-stroke machines, the LTR450R provides controllable, tractable power that makes it effective on tracks, trails, and open terrain.
Fuel delivery is handled by a Keihin FCR carburetor, known for its crisp throttle response and reliability. The engine is paired with a 5-speed manual transmission and a manual clutch, giving riders full control over power delivery. This setup makes the 2006 LTR450R suitable for both competitive racing and aggressive recreational riding.
One of the defining features of the 2006 Suzuki LTR450R is its lightweight aluminum frame, a major advancement in sport ATV design at the time. The aluminum chassis reduces overall weight while increasing rigidity, resulting in sharper handling and improved responsiveness. This frame design gives the LTR450R a planted, stable feel in corners and excellent feedback for aggressive riding.
The suspension on the 2006 LTR450R is fully race-ready. It features fully adjustable front and rear shocks, allowing riders to fine-tune compression, rebound, and preload to match their riding style and terrain. This suspension setup provides excellent bump absorption, precise control, and confidence at high speeds, making the LTR450R a strong performer on motocross tracks and rough off-road terrain.
Braking performance is delivered by hydraulic disc brakes front and rear, providing strong, consistent stopping power. The braking system is well-matched to the LTR450R’s performance capabilities, offering excellent control during aggressive riding and race conditions.
Ergonomics were carefully designed on the 2006 Suzuki LTR450R to enhance rider control and comfort. The narrow bodywork, flat seat profile, and well-positioned footpegs allow riders to move freely and maintain proper body positioning during aggressive riding. The overall layout makes the LTR450R feel natural and intuitive, especially for riders with racing experience.
The styling of the 2006 LTR450R is aggressive and unmistakably race-inspired. Sharp body lines, bold graphics, and a low, wide stance give the quad a competition-ready appearance. The exhaust system and intake design not only enhance performance but also contribute to its muscular look.
Another major advantage of the 2006 Suzuki LTR450R is its strong aftermarket support. Owners can easily find performance upgrades such as exhaust systems, engine tuning components, suspension kits, wheels, tires, and protective accessories. This makes the LTR450R a popular platform for motocross racing, cross-country competition, and high-performance trail riding.
The LTR450R also earned success in professional racing, proving its capability on the national stage. Suzuki’s factory race teams achieved multiple championships with the LTR450R, cementing its reputation as a true race-bred machine. This racing heritage adds to the model’s appeal among enthusiasts and collectors.
Today, the 2006 Suzuki LTR450R remains a highly regarded sport ATV for riders seeking a powerful, reliable, and competitive four-stroke quad. Its combination of advanced engineering, race-proven performance, and aggressive styling ensures it continues to stand out in the sport ATV market.
Whether you’re looking for a track-ready racer, a high-performance recreational ATV, or a piece of modern ATV racing history, the 2006 Suzuki LTR450R delivers precision handling, strong four-stroke power, and championship-level performance.
