2006 Highland 450 MX Technical Analysis & Specification Breakdown

Engineered by Highland for the cross - motocross motorcycle segment, the 2006 Highland 450 MX utilizes a 449 cc (27.4 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 55.7 HP (40.6 kW) at 8,500 rpm while maximum torque reaches 51.1 Nm (37.7 lb-ft) at 7,300 rpm. With a specific output of 124.1 HP per liter and a 1,200 rpm working window between peak torque (7,300 rpm) and peak power (8,500 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 MX measures 103 kg (227 lbs) dry, translating to a power-to-weight ratio of 0.54 HP/kg (1.85 kg per horsepower). Rider ergonomics and chassis geometry center around a 998 mm (39.3 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,485 mm (58.5 in) wheelbase engineered for balanced agility and highway composure. The 7-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
