The 2004 GAS GAS SM 450 carved its niche in the burgeoning supermoto scene, a segment that saw considerable growth in the early 2000s. Emerging from a brand known primarily for its off-road prowess, the SM 450 represented GAS GAS's focused entry into the street-legal, dirt-bike-derived streetfighter category. This era was characterized by manufacturers translating their enduro and motocross expertise into road-going machines, often with minimal modifications beyond wheels, brakes, and lighting. The SM 450 faced direct competition from established players like the KTM 450 SMR and Husqvarna SM 450 R, all vying for the attention of riders seeking an agile, aggressive street machine.

At its heart, the 2004 GAS GAS SM 450 was powered by a 399.00 ccm (24.35 cubic inches) single-cylinder engine, providing a lively power delivery well-suited for its supermoto application. This engine, combined with a remarkably light dry weight of 105.0 kg (231.5 pounds), contributed to the bike's impressive power-to-weight ratio, a key characteristic for supermoto machines. Fuel capacity stood at 9.50 litres (2.51 gallons), offering a reasonable range for urban antics and short blasts. While specific horsepower figures varied, the focus was always on immediate throttle response and tractable torque, ideal for navigating tight corners and quick accelerations.

Riding the SM 450 was a distinctly supermoto experience. The upright stance, typical of the category, provided excellent visibility and control, while the 900 mm (35.4 inches) seat height (if adjustable, lowest setting) positioned the rider high, offering a commanding view over traffic. Its light weight and agile chassis made for incredibly responsive handling, allowing for rapid changes of direction and aggressive lean angles. The suspension setup, likely derived from GAS GAS's off-road bikes, was firm enough to handle road irregularities while offering sufficient travel for spirited riding. This setup, combined with strong braking, made the SM 450 a joy to flick through corners.

The 2004 GAS GAS SM 450 was aimed squarely at enthusiasts who appreciated the raw, unfiltered experience of a supermoto. It was not a touring machine, nor was it designed for long highway stretches. Instead, its target audience comprised riders seeking an engaging, nimble, and somewhat rebellious motorcycle for urban environments, twisty backroads, and occasional track days. For those who valued agility, immediate power delivery, and a distinctive street presence, the SM 450 offered a compelling, albeit specialized, package within the supermotard category.
