2009 Goes 450 X Technical Analysis & Specification Breakdown
Engineered by Goes for the atv motorcycle segment, the 2009 Goes 450 X utilizes a 448.8 cc (27.4 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 51 HP (37.2 kW) at 7,500 rpm while maximum torque reaches 48 Nm (35.4 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and shaft drive (cardan) final drive. With a specific output of 113.6 HP per liter and a 1,000 rpm working window between peak torque (6,500 rpm) and peak power (7,500 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the 450 X measures 199 kg (439 lbs) dry, translating to a power-to-weight ratio of 0.26 HP/kg (3.9 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,265 mm (49.8 in) wheelbase engineered for quick, flickable steering geometry. The 11-liter (2.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
